CommitLimit was a good addition to /proc/meminfo, but we don't usually show
both what's used and what's free: don't waste lines of screenspace, omit
CommitAvail, let the user do the arithmetic as with all the others.  And in
updating that Documentation, removed the long-gone ReverseMaps.

The sixth "data" field of /proc/$pid/statm was sometimes negative: text is
a subset of shared_vm, and so was subtracted twice from total_vm.

The third "shared" field of /proc/$pid/statm in 2.4 was a count of pages in
the mm whose page_count is more than 1 (oddly, including pages shared just
with swapcache).  That's too costly to calculate each time, so 2.6 changed
it to the total file-backed extent.  But Andrea knows apps and users
surprised when (rss - shared) goes negative: we need to provide an rss-like
statistic, close to the 2.4 interpretation.

Something that's quick and easy to maintain accurately is mm->anon_rss, the
count of anonymous pages in the mm.  Then shared = rss - anon_rss gives a
pretty good and meaningful approximation to 2.4's intention: wli confirms
that this will be useful to Oracle too.

Where to show it?  I think it's best to treat this as a bugfix and show it
in the third field of /proc/$pid/statm, after resident, as before - there's
no evidence that the total file-backed extent was found useful.

Albert would like other fields to revert to page counts, but that's a lot
harder: if mprotect can change the category of a page, then it can't be
accounted as simply as this.  Only go that route if real need shown.

The procfs shared_vm accounting in do_mmap_pgoff didn't balance with munmap
in the case of shared anonymous: because file comes in NULL, whereas
vm_file gets set at the end by shmem_zero_setup.

Update file; and update vm_flags (a driver is likely to add VM_IO or
VM_RESERVED, modifying reserved_vm); and update pgoff (doesn't affect
procfs accounting, but could affect vma_merge - though at present all
drivers which modify vm_pgoff set a VM_SPECIAL which prevents merging). 
And do that __vm_stat_account before advancing to make_pages_present.

The NUMA policy for shared memory or tmpfs page allocation was protected by
a semaphore.  It helps to improve scalability if we change that to a
spinlock (and there's only one place that needs to drop and reacquire). 
Oh, and don't even bother to get the spinlock while the tree is empty.

During system boot many probes, etc.  will generate upcalls to userspace
via call_usermodehelper().  This has the effect of calling execve() before
the key subsystem has been initialized, and thus Oopsing on a NULL key_jar
during key_alloc().  Move key_init to security_initcall so that it's called
along with other security initialization routines which have similar
requirements.

This patch fixes 3 problems with the nommu.c support code:

1. export mem_map and vmtruncate (to make them the same as MMU version)

2. update the total_vm usage in mmap routines

Kbuild can't fix up "-I $(src)/.." to the right directory
due to the particular magic transformations it does on -I
arguments. Remove the space, use "-I$(src)/.." and it works.

Hopefully Sam will fix this build issue.

You too can become a superhacker by setting up a cross-compile
environment for all architectures and building "allmodconfig"
trees all day long to find places where others have screwed up.

If an arch Makefile overrides CROSS_COMPILE (e.g. parisc, mips, ...)
then the cc-option call in the main Makefile uses the wrong compiler 
to check for options.

Host drivers should now use the scatterlist rather than accessing
the request directly.  This marks the request pointer as being
deprecated so that host driver authors get a chance to fix their
drivers up before we remove this member.

This converts the PXA MCI driver to use the supplied scatter list
rather than accessing the struct request directly, thereby making
this host driver independent of the block layer.

We also clean up the driver to use a consistent driver name for
resources.

Convert MMCI driver to use the scatter list provided by the upper
MMC layers.  This removes all knowledge of struct request from the
MMCI driver.

This is intended to remove block layer knowledge from MMC host
drivers.  Host drivers are expected to use the scatter list for
data transfers rather than accessing the struct request.
