Forward some UVM from matt-nb5-mips64. Add UVM_KMF_COLORMATCH flag. When uvm_map gets passed UVM_FLAG_COLORMATCH, the align argument contains the color of the starting address to be allocated (0..colormask). When uvm_km_alloc is passed UVM_KMF_COLORMATCH (which can only be used with UVM_KMF_VAONLY), the align argument contain the color of the starting address to be allocated. Change uvm_pagermapin to use this. When mapping user pages in the kernel, if colormatch is used with the color of the starting user page then the kernel mapping will be congruent with the existing user mappings.

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.

Make uvm_map recognize UVM_FLAG_COLORMATCH which tells uvm_map that the 'align' argument specifies the starting color of the KVA range to be returned. When calling uvm_km_alloc with UVM_KMF_VAONLY, also specify the starting color of the kva range returned (UMV_KMF_COLORMATCH) and pass those to uvm_map. In uvm_pglistalloc, make sure the pages being returned have sequentially advancing colors (so they can be mapped in a contiguous address range). Add a few missing UVM_FLAG_COLORMATCH flags to uvm_pagealloc calls. Make the socket and pipe loan color-safe. Make the mips pmap enforce strict page color (color(VA) == color(PA)).

Add better color matching selecting free pages. KM pages will now allocated so that VA and PA have the same color. On a page fault, choose a physical page that has the same color as the virtual address. When allocating kernel memory pages, allow the MD to specify a preferred VM_FREELIST from which to choose pages. For machines with large amounts of memory (> 4GB), all kernel memory to come from <4GB to reduce the amount of bounce buffering needed with 32bit DMA devices.

Remove separate mb_map. The nmbclusters is computed at boot time based on the amount of physical memory and limited by NMBCLUSTERS if present. Architectures without direct mapping also limit it based on the kmem_map size, which is used as backing store. On i386 and ARM, the maximum KVA used for mbuf clusters is limited to 64MB by default. The old default limits and limits based on GATEWAY have been removed. key_registered_sb_max is hard-wired to a value derived from 2048 clusters.

When retiring a swap device with marked bad blocks on it we should update the `# swap page in use' and `# swap page only' counters. However, at the time of swap device removal we can no longer figure out how many of the bad swap pages are actually also `swap only' pages. So, on swap I/O errors arrange things to not include the bad swap pages in the `swpgonly' counter as follows: uvm_swap_markbad() decrements `swpgonly' by the number of bad pages, and the various VM object deallocation routines do not decrement `swpgonly' for swap slots marked as SWSLOT_BAD.

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

Change uvm_km_kmemalloc() to accept flag UVM_KMF_NOWAIT and pass it to uvm_map(). Change uvm_map() to honnor UVM_KMF_NOWAIT. For this, change amap_extend() to take a flags parameter instead of just boolean for direction, and introduce AMAP_EXTEND_FORWARDS and AMAP_EXTEND_NOWAIT flags (AMAP_EXTEND_BACKWARDS is still defined as 0x0, to keep the code easier to read). Add a flag parameter to uvm_mapent_alloc(). This solves a problem a pool_get(PR_NOWAIT) could trigger a pool_get(PR_WAITOK) in uvm_mapent_alloc(). Thanks to Chuck Silvers, enami tsugutomo, Andrew Brown and Jason R Thorpe for feedback.

add a new km flag UVM_KMF_CANFAIL, which causes uvm_km_kmemalloc() to return failure if swap is full and there are no free physical pages. have malloc() use this flag if M_CANFAIL is passed to it. use M_CANFAIL to allow amap_extend() to fail when memory is scarce. this should prevent most of the remaining hangs in low-memory situations.

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.

Reduce some complexity in the fault path -- Rather than maintaining an spl-protected "interrupt safe map" list, simply require that callers of uvm_fault() never call us in interrupt context (MD code must make the assertion), and check for interrupt-safe maps in uvmfault_lookup() before we lock the map.

Change the pmap_enter() API slightly; pmap_enter() now returns an error value (KERN_SUCCESS or KERN_RESOURCE_SHORTAGE) indicating if it succeeded or failed. Change the `wired' and `access_type' arguments to a single `flags' argument, which includes the access type, and flags: PMAP_WIRED the old `wired' boolean PMAP_CANFAIL pmap_enter() is allowed to fail If PMAP_CANFAIL is not specified, the pmap should behave as it always has in the face of a drastic resource shortage: fall over dead. Change the fault handler to deal with failure (which indicates resource shortage) by unlocking everything, waiting for the pagedaemon to free more memory, then retrying the fault.

Keep interrupt-safe maps on an additional queue. In uvm_fault(), if we're looking up a kernel address, check to see if the address is on this "interrupt-safe" list. If so, return failure immediately. This prevents a locking screw if a page fault is taken on an interrupt-safe map in or out of interrupt context.

Change the vm_map's "entries_pageable" member to a r/o flags member, which has PAGEABLE and INTRSAFE flags. PAGEABLE now really means "pageable", not "allocate vm_map_entry's from non-static pool", so update all map creations to reflect that. INTRSAFE maps are maps that are used in interrupt context (e.g. kmem_map, mb_map), and thus use the static map entry pool (XXX as does kernel_map, for now). This will eventually change now these maps are locked, as well.

Add a new `access type' argument to pmap_enter(). This indicates what type of memory access a mapping was caused by. This is passed through from uvm_fault() and udv_fault(), and in most other cases is 0. The pmap module may use this to preset R/M information. On MMUs which require R/M emulation, the implementation may preset the bits and avoid taking another fault. On MMUs which keep R/M information in hardware, the implementation may preset its cached bits to speed up the next call to pmap_is_modified() or pmap_is_referenced().
