  -> 2.5.50-mm2.gz        Full patch
  -> 2.5.50-mm2-shpte.gz  Up to `shpte-always-on', for Dave to work against

Lots of fixes. Some things dropped for various reasons.  A decent
amount of rework against the high-level writeback code.


Since 2.5.50-mm1:

-fbcon-timer-fix.patch
-hugepage-fixes.patch
-ext3-oldalloc.patch
-simplified-vm-throttling.patch
-page-reclaim-motion.patch
-handle-fail-writepage.patch
-activate-unreleaseable-pages.patch
-ipc_barriers.patch
-signal-speedup.patch
-pf_memdie.patch
-suppress-write-error-warnings.patch
-truncate-speedup.patch
-spill-lru-lists.patch
-readdir-speedup.patch       (Linus fixed all the bugs in it)

 Merged

-epoll-bits-0.57.patch
+epoll.patch

 Davide's latest

-aio-dio-really-submit.patch
-aio-dio-deferred-dirtying.patch
-dio-counting.patch

 Folded into other patches.

-reiserfs-readpages.patch

 Dropped - it was causing fsx-linux failures.

+cputimes_stat.patch

 Put the per-cpu times back into /proc/pid/stat, CONFIGurably

-poll-1-wqalloc.patch
-poll-2-selectalloc.patch
-poll-3-alloc.patch
-poll-4-fast-select.patch
-poll-5-fast-poll.patch
-poll-6-merge.patch

 Dropped.  Increased stack utilisation was a concern, and the performance
 benefits are patchy.  Manfred is taking another look at it.

+deadsched-fix.patch

 Deadline scheduler fix

+shpte-nonlinear.patch

 Fix shared pagetables for nonlinear mappings

+pmd-allocation-fix.patch

 Always allocate PMD's out to the top of the virtual address space.

-dcache_rcu-2-2.5.48.patch
-dcache_rcu-3-2.5.48.patch

 Dropped.  Other changes broke it, and Dipankar is redoing a few things
 anyway.

+filldir-checks.patch

 Some copy_*_user checks.

+vmstats-fixes.patch

 Small vm stats fix and enhancement.

+hugetlb-fixes.patch

 Fixes from Rohit.

+writeback-interaction-fix.patch

 I had a few oddities and bogons in the fs/fs-writeback.c code.  This
 patch is a fair-sized revamp, cleanup and general sort-things-out in
 there.  It works better.

+scalable-zone-protection.patch

 Allow runtime tuning of the lower-zone protection ratio.  Needs work.

+page-wait-table-min-size.patch

 Don't allow a one-slot hashed wait table for wait_on_page()

+ext3-transaction-reserved-blocks.patch

 Fix an ext3 assertion failure which is triggerable with corrupt disk
 contents.

+remove-PF_SYNC.patch

 remove the current->flags:PF_SYNC abomination.  Adds a `sync' arg to
 all writepage implementations to tell them whether they are being
 called for memory cleansing or for data integrity.

+dont-inherit-mlockall.patch

 Don't inherit mlockall(MCL_FUTURE) across forks

+bootmem-alloc-alignment.patch

 Improved coalescing of bootmem regions

+ext23_free_blocks-check.patch

 Additional sanity checks in the block allocator.

+blkdev-rlimit.patch

 Don't apply rlimits to blockdev writes.

+readahead-pinned-memory.patch

 Don't allow gargantuan amounts of memory to be pinned in readahead

-page-walk-api-improvements.patch
-page-walk-api-bugfix.patch

 Folded into page-walk-api.patch

+page-walk-api-update.patch

 New stuff from Ingo (needs splitting up and changelogging...)
