Stephen Rothwell a71c1ab50a [PATCH] consolidate SIGEV_PAD_SIZE
Discussing with Matthew Wilcox some of his outstanding patches lead me to
this patch (among others).

The preamble in struct sigevent can be expressed independently of the
architecture.

Also use __ARCH_SI_PREAMBLE_SIZE on ia64.

Joe Korty 4750e2c0c5 [PATCH] add EOWNERDEAD and ENOTRECOVERABLE version 2
Add EOWNERDEAD and ENOTRECOVERABLE to all architectures.  This is to
support the upcoming patches for robust mutexes.

We normally don't reserve parts of the name/number space for external
patches, but robust mutexes are sufficiently popular and important to
justify it in this case.

Matt Mackall c8538a7aa5 [PATCH] remove all kernel BUGs
This patch eliminates all kernel BUGs, trims about 35k off the typical
kernel, and makes the system slightly faster.

Matt Mackall e43379f10b [PATCH] nice and rt-prio rlimits
Add a pair of rlimits for allowing non-root tasks to raise nice and rt
priorities. Defaults to traditional behavior. Originally written by
Chris Wright.

The patch implements a simple rlimit ceiling for the RT (and nice) priorities
a task can set.  The rlimit defaults to 0, meaning no change in behavior by
default.  A value of 50 means RT priority levels 1-50 are allowed.  A value of
100 means all 99 privilege levels from 1 to 99 are allowed.  CAP_SYS_NICE is
blanket permission.

(akpm: see http://www.uwsg.iu.edu/hypermail/linux/kernel/0503.1/1921.html for
tips on integrating this with PAM).

Al Viro 3106dbcd91 [PATCH] __get_unaligned() turned into macro
Turns __get_unaligned() and __put_unaligned into macros.  That is
definitely safe; leaving them as inlines breaks on e.g.  alpha [try to
build ncpfs there and you'll get unresolved symbols since we end up
getting __get_unaligned() not inlined].

Hugh Dickins 8f6c99c11a [PATCH] freepgt: remove arch pgd_addr_end
ia64 and sparc64 hurriedly had to introduce their own variants of
pgd_addr_end, to leapfrog over the holes in their virtual address spaces which
the final clear_page_range suddenly presented when converted from pgd_index to
pgd_addr_end.  But now that free_pgtables respects the vma list, those holes
are never presented, and the arch variants can go.

James Bottomley dae409a277 [PATCH] add Big Endian variants of ioread/iowrite
In the new io infrastructure, all of our operators are expecting the
underlying device to be little endian (because the PCI bus, their main
consumer, is LE).

However, there are a fair few devices and busses in the world that are
actually Big Endian.  There's even evidence that some of these BE bus and
chip types are attached to LE systems.  Thus, there's a need for a BE
equivalent of our io{read,write}{16,32} operations.

The attached patch adds this as io{read,write}{16,32}be.  When it's in,
I'll add the first consume (the 53c700 SCSI chip driver).

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
