    If generic enabled legacy VGA or kbd - disable them
    Slightly different check for work arounds and only do it once
    If there is no klconfig info and we are in the simulator - ignore it
    Update the pxm_to_nasid() routine. It failed for SP configurations and some
    SMP configurations where M-bricks used pxm numbers lower that the first
    c-brick.
    If we don't find the cpu for pxm, search the memblks for it.

It seems to me that this dentry assignment in open_namei is not needed per
the patch below.  On this path, dentry is not referenced.

From: Jens Axboe <axboe@suse.de>

2.6 imposes a 64 frame limit where 2.4 does not (just relies on kmalloc()
failing and limiting frames from that).  That breaks at least on guys app.
With MSF adressing, it's much simpler to be able to ask for a full second
at the time, so I think we should just allow that.  So bump the limit from
64 to CD_FRAMES (which is 75).

From: Jake Moilanen <moilanen@austin.ibm.com>

On a ppc64 logically partitioned system, there can be a setup where function
0 of a PCI-PCI bridge is assigned to one partition and (for example) function
2 is assigned to a second partition.  On the second partition, it would
appear that function 0 does not exist, but function 2 does.  If all the
functions are not scanned, everything under function 2 would not be detected.

This patch allows devices that don't respond to function 0, but do respond to
other functions to be marked with a quirk and have all of their functions
scanned.

From: Jack Steiner <steiner@sgi.com>

The cpu_vm_mask use to be close to the mmu_context_t field in the mm
struct.  Recently some large members were added between "cpu_vm_mask" and
"context".  I suspect that was an oversight.

Here is a patch that puts the fields close together.  This makes it likely
that both fields are in the same cache line.  Since both fields are likely
to be updated at the same time, this may improve performance.

From: Matt Mackall <mpm@selenic.com>

I've been fiddling with cleaning up some old code here and suggest the
following to make Lindent match actual practice more closely. This does:

a) (no -psl)

 instead of

void *
foo(void) {

b) (no -bs) "sizeof(foo)" rather than "sizeof (foo)"

c) (-ncs) "(void *)foo" rather than "(void *) foo"

acked by npiggin.

From: Nikita Danilov <Nikita@Namesys.COM>

shrink_list() checks PageSwapCache() before calling add_to_swap(), this
means that anonymous page that is going to be added to the swap right
now these checks return false and:

 (*) it will be unaccounted for in nr_mapped, and

 (*) it won't be written to the swap if gfp_flags include __GFP_IO but
     not __GFP_FS.

(Both will happen only on the next round of scanning.)

Patch below just moves may_enter_fs initialization down. I am not sure
about (*nr_mapped) increase though.

From: Andi Kleen <ak@suse.de>

When the user gave an address hint in mmap use it as starting point for the
search for !MAP_FIXED.

Currently it is only checked directly and when already used the free area
cache is used as starting point.  With this change you can use mmap(4096,
....) to e.g.  get the lowest free address in your address space, which is
sometimes useful.  For example on x86-64 glibc wants to preferably allocate
thread local data in the first 4GB but use higher addresses when this is
not possible.

This can be a bit more costly in CPU time because it may have to skip over
more VMAs, but gives better semantics for most cases.  Most programs pass
NULL as hint anyways so it won't make any difference for them.

I did it for the generic mmap and for x86-64 for now.  Also minor white
space fixes for x86-64.

From: Jes Sorensen <jes@trained-monkey.org>

nr_free_pages() is expensive, especially on large SMP machines.  The patch

It's from Pascal Schmidt and adds write protect handling to ide-cd along

From: Maneesh Soni <maneesh@in.ibm.com>

The patch fixes locking in proc_check_root().  It brings is_subdir() call
under vfsmount_lock.  Holding vfsmount_lock will ensure mnt_mountpoint
dentry is intact and the dentry does not go away while it is being checked
in is_subdir().

From: Maneesh Soni <maneesh@in.ibm.com>

o The following patch fixes is_subdir() races with d_move. Due to concurrent
  d_move, in is_subdir() we can end up accessing freed d_parent pointer in
  case of pre-emptible kernel. To avoid this we can use rcu_read_lock() and
  rcu_read_unlock().

o This also fixes the seqlock uses in is_subdir() as we need to restart the
  the inner loop with the origianl new_dentry passed to the routine in case
  of any rename occured while we are traversing d_parent links.

I came across this C standards issue while cross-compiling the Linux kernel
with gcc on Solaris.  The file gen_crc32table.c uses the non-standard type
u_int32_t.  It's possible that the host machine's sys/types.h does not
define u_int32_t.  The attached patch replaces u_int32_t with the POSIX
standard uint32_t and includes POSIX inttypes.h instead of sys/types.h.

This patch fixes menuconfig so it can display help text for individual
choice group config entries.

Previously it would only display the help text attached to the "choice"
item.  There was no way to display the help attached to individual config
entries inside the choice group.  Typically, the "choice" item has no help
text, and all the useful help is attached to the individual entries, so
this was a bit of a problem.
