We check nvram_fetch/nvram_store against -1, so better not make these
unsigned.

Based on feedback from the hardware guys align jiffies and tb_last_stamp.
We update both regularly and there are other read only, heavily accessed
things that share those cachelines.

We were allocating radix tree nodes in the interrupt code with GFP_KERNEL
under a spinlock.  Change it to GFP_ATOMIC.

The patch below moves some declarations from C files into the appropriate
header file in include/asm-ppc (and removes an unused local variable in a
function).

From: Paul Mackerras <paulus@samba.org>

Matt Porter's recent changes broke the compile for non-4xx ppc32 systems,
unfortunately.  I get an error that mfdcr is not defined in
include/asm-ppc/ocp.h when compiling for powermac (reasonable, since the
mfdcr instruction only exists on 4xx processors).  The patch below fixes
it.

This patch fixes the condition where prefetching cache lines beyond a
buffer can cause data corruption on non cache coherent PPCs.  It is a port
of the version that went into 2.4.  From Eugene Surovegin
<ebs@ebshome.net>.

From: Matt Porter <mporter@kernel.crashing.org>

This patch implements/uses __flush_dcache_icache_page() which kmaps on a
Book E part, but keeps the existing behavior on other PowerPCs which can
disable the MMU.

From: Olaf Hering <olh@suse.de>

ext3 as module is not possible in 2.6.6, clear_pages, called from clear_page,
is not exported.

Also, unexport clear_page(), which is an inline.

inode->i_flags should never contain fs-specific flags.  In fact, it doesn't;
the checks against it cause "chattr +T" to be useless for ext[23].  Same bug
was in befs as well.

We already have block number (inode->i_ino), so there is no need to calculate
it from befs_block_run before sb_bread() call (this is what befs_bread_iaddr()
do).

From: "Sergey S. Kostyliov" <rathamahata@php4.ru>

LBD patch merged long time ago, so it is safe to pass u64 block numbers to
sb_bread() when sector_t is large enough.

      me.

The big-SMP guys are seeing high CPU load due to del_timer_sync()'s
inefficiencies.  The callers are fs/aio.c and schedule_timeout().

We note that neither of these callers' timer handlers actually re-add the
timer - they are single-shot.

So we don't need all that complexity in del_timer_sync() - we can just run
del_timer() and if that worked we know the timer is dead.

Add del_single_shot_timer(), export it to modules and use it in AIO and
schedule_timeout().


(these numbers are for an earlier patch, but they'll be close)

Before:             32p     4p
     Warm cache   29,000    505
     Cold cache   37,800   1220

After:              32p     4p
     Warm cache       95     88
     Cold cache    1,800    140

[Measurements are CPU cycles spent in a call to del_timer_sync, the average
of 1000 calls. 32p is 16-node NUMA, 4p is SMP.]
