The recent slab alignment changes broke an unknown number of architectures
(parisc and x86_64 for sure) by causing task_structs to be insufficiently
aligned.

We need good alignemnt because architectures do things like dumping FP state
into the task_struct with instructions which require particular alignment (I
think).

So change the default alignment to L1_CACHE_BYTES, which is what we used to
have, via SLAB_HW_CACHE_ALIGN.

This patch updates the MTD concatenating driver from MTD CVS, which
fixes issues found with this driver which concatenates multiple MTD
devices into one MTD device.

POSIX sez: "If len is zero, all data following offset is specified."

From: David Gibson <david@gibson.dropbear.id.au>

The 32->64 bit syscall translation layer on ppc64 incorrectly sign-
extends rather than zero-extending the second parameter to shmget(),
which should be a size_t.  This means that it is impossible to shmget()
more 2GB or more from a 32-bit process.

Enable basic profiling code on s390 depending on CONFIG_PROFILING, not
CONFIG_OPROFILE.

CONFIG_PROFILING should enable the generic profiling code here, even if
CONFIG_OPROFILE is not set.  Note that the identical code on i386 is always
compiled in, regardless of CONFIG_PROFILING and CONFIG_OPROFILE.

Fix http://bugme.osdl.org/show_bug.cgi?id=2540

It prevents PnP detection if devices were already detected by SuperIO.

Ensure that when we send the SETATTR call after doing an O_EXCL create,
we always set the atime and ctime fields.

See RFC1813 for details on why the server is allowed to clobber these
two fields in order to cache a verifier that protects CREATE in case of
a timeout+resend from the client.

Move HW interrupt register init. to the proper place
and don't force an interrupt if the IRQ is disabled
or in progress.

No pun intended, but X can't work if it can't turn on eXecute-permission
on the some data pages...

Just found I never changed type of move_page_tables when I changed it to
return offset: einormous mremap moves would fail on 64-bit.

To avoid various livelocks, the writeback code parks all the dirty inodes onto
sb->s_io and then works through that list until it is empty.  This assumes
that each inode will be moved to some other list as it is processed.

But there's a loophole: if the ->writepages() implementation does nothing at
all, the inode is not redirtied (which would move it to s_dirty).  This causes
s_io to not empty and pdflush goes nuts.

So when this happens, move the inode onto s_dirty within
__sync_single_inode().  Use list_move_tail() to attempt to preserve the
time-ordering of the s_dirty list.

This fixes a locking problem noted by Tim Hockin:
    * /proc/swaps uses seq_file code, calling seq_path() with swaplock held
    * seq_path() calls d_path()
    * d_path() calls mntput() which might_sleep()

We add a new semaphore protecting insertions/removals in the set of swap
components + switch of ->start()/->stop() to the same semaphore [fixes
deadlocks] + trivial cleanup of ->next().

Early POWER5 revisions (<DD2.1) have a problem requiring slbie
instructions to be repeated under some circumstances.  The patch below
adds a workaround (patch made by Anton Blanchard).

This fix is from Paul Mackerras and was applied in 2.4 sometime late
last year.

On ppc64, touching addresses between the highest other mapping and the
stack can cause the stack to be extended way, way down, rather than
causing a SEGV as you would expect.  This patch only allows the stack
mapping to be extended to cover addresses actually within the stack
(as determined by looking at the process's r1).  This fix is ported
from 2.4

This fixes failures on the LTP's shmdt01, munmap01 and munmap02 tests.

In ide_init_default_irq() patch I overlooked that ppc_ide_md.init_hwif_ports()
called from generic ide_init_hwif_ports() can set hwif->irq and it will
be overwritten by ide_init_default_irq() if CONFIG_PCI is defined.  Fix
it.

I will clean it up properly later after killing ide_init_hwif_ports() on
ARM{26}.  Doing it now is just wasted effort.
