Sync with HEAD. Follow the merge of pmap.c on i386 and amd64 and move pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup code to restore CR4 before jumping back into kernel space as the large page option might cover that.

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.

x86 changes for pcc and LKMs. - Replace most inline assembly with proper functions. As a side effect this reduces the size of amd64 GENERIC by about 120kB, and i386 by a smaller amount. Nearly all of the inlines did something slow, or something that does not need to be fast. - Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL. In that case make them inlines. Makes curlwp LKM and preemption safe. - Make bus_space and bus_dma more LKM friendly. - Share a few more files between the ports. - Other minor changes.

- When zeroing/copying pages, use SSE2 movtni to avoid polluting the cache. - By default, align assembly routines on 32-byte starting boundaries. - There are now 8 interrupt priority levels, half of which are softints. Update intrdefs.h to match. - Always clear/set spinlock words - removes lots of ifdefs. - Remove the horrible ci_self150 hack that I introduced. - Overhaul how TLB shootdown is performed. Inspired by a similar change in OpenBSD but implemented quite differently. This should be a lot faster but I have not benchmarked it yet.

Pull up following revision(s) (requested by pavel in ticket #397): sys/arch/i386/i386/machdep.c: revision 1.589 sys/arch/i386/i386/pmap.c: revision 1.195 PR port-i386/34186 by Wolfgang Stukenbrock: mapping of msgbuf during startup may map invalid physical adresses "If the last available physical memory segment on a system is less 16k, than the startup code that will map the kernel message buffer, will fail and map physical pages behind the last segment. This may either only lead to a message buffer without physical memory behind it, or to an overlapping message buffer with something else." Fix by allowing multiple physical memory segments to be used for msgbuf. Also remove some leftover msgbuf manipulation from pmap.c. Fix supplied by Wolfgang Stukenbrock in the PR, with some modifications from me, mainly to use the already existing constant VM_PHYSSEG_MAX as the static limit of number of msgbuf segments.

Just checking a global marker (pm_hiexec) for the highest executable address currently in effect does not always work: There might be more instances of the code segment selector in other threads, on other CPUs and in *jmp_bufs. So always check whether the CS needs updating, if it is not already set to the "BIG" value. This code needs more cleanup, this is considered a stopgap fix only.

add support for non-executable mappings (where the hardware allows this) and make the stack and heap non-executable by default. the changes fall into two basic catagories: - pmap and trap-handler changes. these are all MD: = alpha: we already track per-page execute permission with the (software) PG_EXEC bit, so just have the trap handler pay attention to it. = i386: use a new GDT segment for %cs for processes that have no executable mappings above a certain threshold (currently the bottom of the stack). track per-page execute permission with the last unused PTE bit. = powerpc/ibm4xx: just use the hardware exec bit. = powerpc/oea: we already track per-page exec bits, but the hardware only implements non-exec mappings at the segment level. so track the number of executable mappings in each segment and turn on the no-exec segment bit iff the count is 0. adjust the trap handler to deal. = sparc (sun4m): fix our use of the hardware protection bits. fix the trap handler to recognize text faults. = sparc64: split the existing unified TSB into data and instruction TSBs, and only load TTEs into the appropriate TSB(s) for the permissions. fix the trap handler to check for execute permission. = not yet implemented: amd64, hppa, sh5 - changes in all the emulations that put a signal trampoline on the stack. instead, we now put the trampoline into a uvm_aobj and map that into the process separately. originally from openbsd, adapted for netbsd by me.

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).

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. From art@openbsd.org.

Fix from Frank van der Linden to TLB shootdown: "... both a 'flushu' (do a normal TLB flush, but not the PG_G entries) and one or more PG_G entries could have been in the shootdown queue. pmap_tlb_shootnow() would then only have done a plain tlb flush, meaning that the PG_G address(es) on the shootdown queue weren't handled. "For this to happen you'd have to have 2 conditions: 1) the max. number of items on the queue was exceeded, with only plain (user) entries on the queue, and 2) after this event happened, a few PG_G entries were added. "This could triggered by an exec, which unmaps the whole process' map, usually causing > 16 'plain' entries, and pmap_remove_ptes wanting to free a pv page, causing a PG_G entry. The latter would then not be flushed from the TLB." Fix is to make we don't miss PG_G entries after a flushu.

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.

Update pmap_update to now take the updated pmap as an argument. This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment. Currently this is a no-op on most platforms, so they should see no difference. Reviewed by Jason.

Work around the problem that causes kern/12554. Basically, there are some pathological cases that cause pmap_page_protect() to be called on a wired page to revoke all mappings. We need to skip mappings that are actually wired to prevent Bad things from happening later. THIS IS JUST A WORK-AROUND. We need to prevent the pathological behavior from happening in UVM to begin with. But it's unclear what the right solution is there, right now.

Clean up the TLB invalidation logic. Remove the last vestiges of the old "remove record" stuff, and just use the shootdown path, even for uniprocessor kernels. Change the shootdown path to defer actually peforming work (or sending the IPI to signal other processors to begin work) until explicitly triggered by a call to pmap_tlb_shootnow(). Also remove all of the PTP and PV entry stealing code -- it's complicated, not often called, and not really useful anymore now that UVM itself can handle pmap_enter() failures.

Mirror a change made on the trunk: Don't equate pmap_update() with tlbflush(), but instead call tlbflush() when that's what we mean (currently everywhere, except in the one place in MI code where it is called).

Don't equate pmap_update() with tlbflush(), but instead call tlbflush() when that's what we mean (currently everywhere, except in the one place in MI code where it is called). The whole pmap_update() thing needs to be reexamined, but this helps to clarify things a little with the currently-defined semantics of that function.

Miscellaneous TLB invalidation/shootdown fixes. - when deleting PTP's, make sure to invalidate and shoot down the PTP mapping. (code from Jason Thorpe) - when we run out of shootdown queue jobs, don't lose the deferred shootdowns for the current cpu (<homer>Doh!</homer>) All this needs to be rewritten again.

Update from trunk: Move the TSS selector out of the PCB and put it into mdproc. We need to access this when we have the proclist locked for reading, and thus cannot store it in the PCB (which may be swapped out). As part of this, call pmap_activate() from cpu_switch() to switch to the new address space, and refresh the PCB's copy of the LDT selector from the pmap structure (see above paragraph). We need to do this for MP support anyhow. Fixes a "panic: spinlock_switchcheck: CPU 0 has 1 spin locks" via gdt_compact() reported by Nathan Williams.

Instead of checking vm_physmem[<physseg>].pgs to determine if uvm_page_init() has completed, add a boolean uvm.page_init_done, and test against that. Use this same boolean (rather than pmap_initialized) in pmap_growkernel() to determine if we are being called via uvm_page_init() to grow the kernel address space. This fixes a problem on some i386 configurations where pmap_init() itself was needing to have the kernel page table grown, and since pmap_initialized was not yet set to TRUE, pmap_growkernel() was choosing the wrong code path. Fix tested by Havard Eidnes.

several fixes:
1. in pmap_steal_ptp(), don't trylock the pmap that wants a ptp,
the caller already has it locked.
2. do not panic in pmap_enter() due to memory allocation failures when
the PMAP_CANFAIL flag is given. to this end, move all such panics
from the lower-level routines to pmap_enter() and pmap_growkernel()
where we can check for this flag.
3. add #ifdef DIAGNOSTIC around all panics which are only reachable
if there's a bug or a hardware error.

Preliminary TLB shootdown support. In liu of previous deferred invalidation support, use TLB shootdown queues even on uniprocessor. Defer enabling global page support in CR4 until processor class has been identified. On a GENERIC kernel which includes 386 support, turning on global page support before identifycpu has set cpu_class results in stale global TLB entries which confuse the MP BIOS probe code.

two changes to prevent the kernel's pmap from being locked recursively
via interrupts:
(1) pmap_map_ptes() and pmap_unmap_ptes() don't need to do anything to
map the kernel's pmap, since all pmaps contain the kernel's PTPs.
this fixes interrupt-context calls to pmap_extract().
(2) pmap_kenter_*() and pmap_kremove() no longer adjust the kernel pmap's
resident and wired counters.

Fix another locking error: if freeing a PV entry, don't attempt to free a PV page if the PV entry was associated with the kernel pmap, since the kernel pmap is locked, and freeing the page will execute a code path which will attempt to lock it again, resulting in deadlock. No real loss, since the next time a PV entry is freed, the page will be freed, too.

Set the p-v list head to NULL if there are no valid mappings. This should be not necessary because the pv_pmap member is already set to NULL in this case which should keep the pv_next pointer from being followed. However, PR port-i386/5291 reports that this measure helps in at least one case (VINO). Reviewed by Chuck Cranor, final fix is functionally identical to the PR's proposal.

When preset this way, they won't be filled in / calculated. - Readable by sysctl using machdep.nkpde, machdep.biosbasemem and machdep.biosextmem. - nkpde is calculated as: min(NKPDE_MAX, NKPDE_BASE + (biosextmem >> 10) * NKPDE_SCALE) Where NKPDE_MAX is 31, NKPDE_BASE is 4, NKPDE_SCALE = 1.

(Most if it is unnecessary.) * Allocate pv_entry's in pages, and keep a list of free entries in each page, and a list of pages with free entries. (Trying to reduce malloc() overhead, and improve locality of reference.) * Remove a couple of macros that aren't really useful. * Remove pmap_kernel() completely.
