Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Implement sharing of vnode_t::v_interlock amongst vnodes:
- Lock is shared amongst UVM objects using uvm_obj_setlock() or getnewvnode().
- Adjust vnode cache to handle unsharing, add VI_LOCKSHARE flag for that.
- Use sharing in tmpfs and layerfs for underlying object.
- Simplify locking in ubc_fault().
- Sprinkle some asserts.

Discussed with ad@.

can be retrieved from struct vm_page_md *.

Start changing this to be ready for device page (XIP).  The basic rule is
device pages don't have struct vm_page * objects.  Instead per-page data

Apply some band-aid to pmap_activate() for PR kern/41058:

There's a corner case here which can leave turds in the cache as
reported in kern/41058. They're probably left over during tear-down and
switching away from an exiting process. Until the root cause is identified
and fixed, zap the cache when switching pmaps. This will result in a few
unnecessary cache flushes, but that's better than silently corrupting data.

Also remove an extraneous return statement in pmap_page_protect() which
crept in during the matt-armv6 merge.

Remove uarea swap-out functionality:

- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Change pv_entries to use SLIST.

For VIPT caches, keep track of when pages are dirty so that their content
can be flushed back to main memory.  This is done when the page is
read-only mapped by more than 1 color.  Pages become when either their
modified bit gets set or an unmanaged writeable page is mapped.  When
a page in unmapped or changed to read-only, run pmap_vac_me_harder in
case the page can be mapped read-only.

Thanks are given to Imre Deak for giving me the idea to assert for PVF_DIRTY.

There's really no need to switch VM contexts within cpu_switchto() as
MI code always calls pmap_deactivate/pmap_activate on context switch.

Instead, just record the last active lwp (or NULL if it exited) and
defer switching VM context to pmap_activate(). This saves an additional
function call overhead in cpu_switchto().

While here, g/c unused cpuswitch.S local .Lblock_userspace_access.

Add support for kcore headers to arm32 kernel core dumps.

The kcore code is based on i386's kcore header handling.

Having an asm stub for dumpsys, to dump the registers onto the stack, and
then call the C code to do the memory dump is based on amd64's core dump
code.

This allows a successful core dump on cats.

Part of fixing PR cats/18026.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

ARM cpu_switchto() has been partially broken since yamt-idlelwp was merged
as its cache/tlb management smarts relied too heavily on pre-merge context-
switch behaviour. See PR kern/36548 for one manifestation of the breakage.

To address this:
 - Ditch the shadow pmap variables in the PCB (pagedir, l1vec, dacr, cstate)
   as it was too easy for them to get out of sync with the pmap.
 - Re-write (and fix) the convoluted cpuswitch.S cache/tlb ASM code in C.
   It's only slightly less efficient, but is much more readable/maintainable.
 - Document cpufuncs.cf_context_switch() as being C-callable.
 - pmap_activate() becomes a no-op if the lwp's vmspace is already active.
   (Good performance win, since pmap_activate() is now invoked on every
   context-switch, even though ARM's cpu_switchto() already does all the
   grunt work)

XXX: Some CPU-specific armXX_context_switch() implementations (arm67,
arm7tdmi, arm8) always flush the I+D caches. This should not be necessary.
Someone with access to hardware (acorn32?) needs to deal with this.

In pmap_activate restore interrupts to their previous state rather than
always enabling them.

It's not clear if this actually caused any problems, but it seems safer
to restore to the previous state in case pmap_activate is ever called
with interrupts disabled.

	sys/arch/arm/arm32/pmap.c: revision 1.158
From Scott Allan in http://mail-index.netbsd.org/port-arm/2006/07/26/0000.html
I ran into a problem when I tried to set up a mapping that started at
virtual address 0xFFF00000 and was 0x00100000 long.  In other words, the
mapping should have gone to the end of the 32 bit address space.  The
mapping was made with no problem, but pmap_devmap_find_va() wouldn't
find an address within the mapping.  For example, if I told it to find a
mapping for 0x1000 bytes at 0xFFF01000, it would try to make sure that
0xFFF01000 was greater than 0xFFF00000 and that (0xFFF01000+0x1000) was
less than (0xFFF00000 +0x00100000).  However, that last expression
(0xFFF00000+0x00100000) wrapped around to be simply 0x00000000 so it
wasn't found.  This patch fixes this problem in pmap_devmap_find_va()
and pmap_devmap_find_pa() by subtracting one off of the

Since pmap_page_remove() is called from pmap_page_protect(), don't modify
the current pmap's pm_cstate if we have to flush the TLB, as callers of
pmap_page_protect() are not required to invoke pmap_update() afterwards.

Otherwise we can end up with a pm_cstate which is inconsistent with reality
in the TLB, which can lead to future TLB flushes being erroneously skipped.

Simplify the way the bounds of the managed kernel virtual address
space is advertised to UVM by making virtual_avail and virtual_end
first-class exported variables by UVM.  Machine-dependent code is
responsible for initializing them before main() is called.  Anything
that steals KVA must adjust these variables accordingly.

This reduces the number of instances of this info from 3 to 1, and
simplifies the pmap(9) interface by removing the pmap_virtual_space()
function call, and removing two arguments from pmap_steal_memory().

This also eliminates some kludges such as having to burn kernel_map
entries on space used by the kernel and stolen KVA.

This also eliminates use of VM_{MIN,MAX}_KERNEL_ADDRESS from MI code,
this giving MD code greater flexibility over the bounds of the managed
kernel virtual address space if a given port's specific platforms can
vary in this regard (this is especially true of the evb* ports).

Some ARM32_PMAP_NEW-related cleanup:
* Define a new "MMU type", ARM_MMU_SA1.  While the SA-1's MMU is basically
  compatible with the generic, the SA-1 cache does not have a write-through
  mode, and it is useful to know have an indication of this.
* Add a new PMAP_NEEDS_PTE_SYNC indicator, and try to evaluate it at
  compile time.  We evaluate it like so:
  - If SA-1-style MMU is the only type configured -> 1
  - If SA-1-style MMU is not configured -> 0
  - Otherwise, defer to a run-time variable.
  If PMAP_NEEDS_PTE_SYNC might evaluate to true (SA-1 only or run-time
  check), then we also define PMAP_INCLUDE_PTE_SYNC so that e.g. assembly
  code can include the necessary run-time support.  PMAP_INCLUDE_PTE_SYNC
  largely replaces the ARM32_PMAP_NEEDS_PTE_SYNC manual setting Steve
  included with the original new pmap.
* In the new pmap, make pmap_pte_init_generic() check to see if the CPU
  has a write-back cache.  If so, init the PT cache mode to C=1,B=0 to get
  write-through mode.  Otherwise, init the PT cache mode to C=1,B=1.
* Add a new pmap_pte_init_arm8().  Old pmap, same as generic.  New pmap,
  sets page table cacheability to 0 (ARM8 has a write-back cache, but
  flushing it is quite expensive).
* In the new pmap, make pmap_pte_init_arm9() reset the PT cache mode to
  C=1,B=0, since the write-back check in generic gets it wrong for ARM9,
  since we use write-through mode all the time on ARM9 right now.  (What
  this really tells me is that the test for write-through cache is less
  than perfect, but we can fix that later.)
* Add a new pmap_pte_init_sa1().  Old pmap, same as generic.  New pmap,
  does generic initialization, then resets page table cache mode to
  C=1,B=1, since C=1,B=0 does not produce write-through on the SA-1.

A few minor tweaks.

Use pmap_free_pvs in pmap_remove, should save on the overhead of freeing
each pv on it's own.

Correctly set ptp when calling pmap_enter_pv, this adds more overhead, but
the effect is minimal.  Timings show that it increases gmake's make configure
step from 2:07.90 to 2:08.90.  I've more optimisations planned that should
negate this increase.

Enable caching on kernel and user page tables.  This saves having
to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).

We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).

From trunk:

Add the brutal hack that allows us to limp along using the read/write
cache line allocation policy on XScale CPUs: in pmap_enter(), if the
pmap is the kernel pmap, clear the X-bit in the PTE, thus disabling
read/write-allocate for managed kernel mappings.

Yes, this is ugly.  But it makes userland code run with r/w-allocate,
which is a huge improvement on systems with low core memory performance.

Overhaul how DMA ranges work in the ARM bus_dma implementation.

A new "arm32_dma_range" structure now describes a DMA window, with
a system address base, bus address base, and length.  In addition to
providing info about which memory regions are legal for DMA, the new
structure provides address translation support, as well.

As before, if a tag does not list any ranges, then all addresses are
considered valid, and no DMA address translation is performed.

This allows us to remove a large chunk of code which was duplicated and
tweaked slightly (to do the address translation) from the stock ARM
bus_dma in the XScale IOP and ARM Integrator ports.

Test compiled on all ARM platforms, test booted on Intel IQ80321 and Shark.

Move the calls to uvm_page_physload() out of pmap_bootstrap() and
into platform-specific initialization code, giving platform-specific
code control over which free list a given chunk of memory gets put
onto.

Changes are essentially mechanical.  Test compiled for all ARM
platforms, test booted on Intel IQ80321 and Shark.

Discussed some time ago on port-arm.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

In pmap_copy_page_xscale(), put the source page in the mini-data
cache, as well.  The mini-data cache is 2-way, so src and dst won't
clobber each other, and the smallness of the cache doesn't matter,
since we access each page once sequentially.

While we still have to do the initial clean of the source page, this
saves another 4K of main D$ pollution, and also means we don't have
to do 2 cache passes after the copy is complete (i.e. we can skip the
invalidation of the source page in the main cache, since it's no longer
there).

Define 2 classes of ARM MMUs:

1. XScale (can be used as generic, but also has certainly nifty extensions).

Define abstract PTE bit defintions for each MMU class.  If only one MMU
class is configured into the kernel (based on CPU_* options), then we
get the constants for that MMU class.  Otherwise we indirect through
varaibles set up via set_cpufuncs().

XXX The XScale bits are currently the same as the generic bits.  Baby steps.

* Add a new function, arm32_vector_init(), which takes the virtual

  over, and performs all vector page initialization, including setting

The target page of pmap_zero_page(), pmap_pageidlezero(), and

Add assertions in #ifdef DEBUG that assert this invariant.

This shaves some cycles off the frequently-called pmap_zero_page()

structure, and one less function call to clean the page).

Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

Implement pmap_growkernel for arm32 based ports.
Note that this has been compiled on some systems, cats, IQ80310, IPAQ, netwinder and shark (note that shark's build is currently broken due to other reasons), but only actually run on cats.
Shark doesn't make use of the functionality as I believe there has to be a correlation between OFW and the kernel tables so that calls into OFW work.

Change pmap_map_entry() to work like pmap_map_chunk(): take a pointer
to the L1 table and a virtual address, and no pointer to the L2 table.
The L2 table will be looked up by pmap_map_entry(), which will panic
if the there is no L2 table for the requested VA.

NOTE: IT IS EXTREMELY IMPORTANT THAT THE CORRECT VIRTUAL ADDRESS
BE PROVIDED TO pmap_map_entry()!  Notably, the code that mapped
the kernel L2 tables into the kernel PT mapping L2 table were not
passing actual virtual addresses, but rather offsets into the range
mapped by the L2 table.  I have fixed up all of these call sites,
and tested the resulting kernel on both an IQ80310 and a Shark.
Other portmasters should examine their pmap_map_entry() calls if
their new kernels fail.

Overhaul of the ARM cache code.  This is mostly a simplification
pass.  Rather than providing a whole slew of cache operations that
aren't ever used, distill them down to some useful primitives:

	icache_sync_all         Synchronize I-cache
	icache_sync_range       Synchronize I-cache range

	dcache_wbinv_all        Write-back and Invalidate D-cache
	dcache_wbinv_range      Write-back and Invalidate D-cache range
	dcache_inv_range        Invalidate D-cache range
	dcache_wb_range         Write-back D-cache range

	idcache_wbinv_all       Write-back and Invalidate D-cache,
				Invalidate I-cache
	idcache_wbinv_range     Write-back and Invalidate D-cache,
				Invalidate I-cache range

Note: This does not yet include an overhaul of the actual asm files
that implement the primitives.  Instead, we've provided a safe default
for each CPU type, and the individual CPU types can now be optimized
one at a time.

When clearing the modified bit for modified emulation, don't turn
caching on for a page just because we are clearing the writable bit in
the PTE: this is incompatible with the way pmap_vac_me_harder works,
and the code in the modified emulation handler doesn't know about
recalculating the cachable attributes (nor should it, IMO).

Also, if we are invalidating a page, flush its TLB entry; for some
reason we were only doing this when clearing the Write or modified
bits.

These patches together seem to solve the random seg-faults that were
still occuring occasionally under heavy paging.

On processors that support both write-through and write-back cacheing
(eg ARM920), the mode in which the processor operates is governed by
the use of both the PT_C and PT_B bits:

	PT_C=1,PT_B=1 -> Write-back
	PT_C=1,PT_B=0 -> Write-through

To support this define pte_cache_mode (initialized to PT_C|PT_B) and
use that when enabling cacheing for a page.

With a diagnostic kernel, printing out a message each time we fail
to allocate a L1 pt is often enough to bring the system to its knees:
so make the messages PDEBUG(0,...).

However, even with this step having more than a small number of
processes searching for a L1 pt can still be enough to bring the system
down, since they all run at high priority and sleep for very little time,
thus blocking out user code from completing.  So implement an exponential
backoff when waiting for a page table, so that we don't hog the CPU when
memory is scarce.

Tested by running a make of the C compiler with "gnumake -j30" (and plenty
of swap space).

a whole bunch of changes to improve performance and robustness under load:

 - remove special treatment of pager_map mappings in pmaps.  this is
   required now, since I've removed the globals that expose the address range.
   pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
   no longer any need to special-case it.
 - eliminate struct uvm_vnode by moving its fields into struct vnode.
 - rewrite the pageout path.  the pager is now responsible for handling the
   high-level requests instead of only getting control after a bunch of work
   has already been done on its behalf.  this will allow us to UBCify LFS,
   which needs tighter control over its pages than other filesystems do.
   writing a page to disk no longer requires making it read-only, which
   allows us to write wired pages without causing all kinds of havoc.
 - use a new PG_PAGEOUT flag to indicate that a page should be freed
   on behalf of the pagedaemon when it's unlocked.  this flag is very similar
   to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
   pageout fails due to eg. an indirect-block buffer being locked.
   this allows us to remove the "version" field from struct vm_page,
   and together with shrinking "loan_count" from 32 bits to 16,
   struct vm_page is now 4 bytes smaller.
 - no longer use PG_RELEASED for swap-backed pages.  if the page is busy
   because it's being paged out, we can't release the swap slot to be
   reallocated until that write is complete, but unlike with vnodes we
   don't keep a count of in-progress writes so there's no good way to
   know when the write is done.  instead, when we need to free a busy
   swap-backed page, just sleep until we can get it busy ourselves.
 - implement a fast-path for extending writes which allows us to avoid
   zeroing new pages.  this substantially reduces cpu usage.
 - encapsulate the data used by the genfs code in a struct genfs_node,
   which must be the first element of the filesystem-specific vnode data
   for filesystems which use genfs_{get,put}pages().
 - eliminate many of the UVM pagerops, since they aren't needed anymore
   now that the pager "put" operation is a higher-level operation.
 - enhance the genfs code to allow NFS to use the genfs_{get,put}pages
   instead of a modified copy.
 - clean up struct vnode by removing all the fields that used to be used by
   the vfs_cluster.c code (which we don't use anymore with UBC).
 - remove kmem_object and mb_object since they were useless.
   instead of allocating pages to these objects, we now just allocate
   pages with no object.  such pages are mapped in the kernel until they
   are freed, so we can use the mapping to find the page to free it.
   this allows us to remove splvm() protection in several places.

The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Checking a whole host of pmap changes:
Improved locking (not that we actually use it on a uniprocessor, but one day :)
Removed unneeded splvm's
tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap  (based on diff from richard E)
Adopted pv entry allocation mechanism from i386.
Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits.
ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove.

Also implemented a page zeroing function when the processor is idling.  Note that hpcarm may wish to disable this.

I believe this code to be stable, if anyone has any problems please shout up.

Rework the pmap_release code to not have to walk the ptpt, it now uses a uvm_object to track the allocated vm_pages, this means it can free off the entries in the uvm_object.

Testing shows that it's about 5% faster on the make configure step for gmake.

A couple of tidy ups to pmap:
pmap_t -> struct pmap * in pmap.c and pmap.h
kernel_pmap -> pmap_kernel() everywhere.

Compiled and booted on riscpc and cats.

clean up pmap_k{enter_pa,remove}():
a page is allowed to be mapped normally when k-mapped.
use UVM_PGA_ZERO to get zeroed pages rather than zeroing here.

Improve the vac_me_harder function, it is now slightly faster, however pmap_enter_pv is also now slightly slower, so they appear to balance out.

Note that I've some ideas in the works on how to improve the pv handling, so the slow down is short term only.

Also added non-advertising licence and copyright to myself and richard.

Add a pmap_map_ptes function to map another process page table entries into the current pmap (similair to pmap_pte) but this allows multiple use of it, rather than repeated calls of pmap_pte for pte, map_ptes returns a pointer to the va where the entries were mapped so it can be reused ptes can be found by indexing into it.

Update some of the functions that use pmap_pte to pmap_map_ptes.

Note that there's a dummy macro for pmap_unmap_ptes, this is because at some point locking will be needed, so we need to be able to unlock them.

Performance gain seems to be minimal, however long term it should help improve things.

This is similair to the i386 pmap_map_ptes, however it's based on a version from Richard Earnshaw.

Sprinkle pmap_update() calls after calls to:
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

anything, and the interface itself wasn't as flexible as
callers would have probably liked.
