fs/partitions/msdos: add support for large disks

In order to use disks larger than 2TiB on Windows XP, it is necessary to
use 4096-byte logical sectors in an MBR.

Although the kernel storage and functions called from msdos.c used
"sector_t" internally, msdos.c still used u32 variables, which results in
the ability to handle XP-compatible large disks.

This patch changes the internal variables to "sector_t".

mmc: fix incorrect interpretation of card type bits

In the extended CSD register the CARD_TYPE is an 8-bit value of which the
upper 6 bits were reserved in JEDEC specifications prior to version 4.4.
In version 4.4 two of the reserved bits were designated for identifying
support for the newly added High-Speed Dual Data Rate.  Unfortunately the
mmc_read_ext_csd() function required that the reserved bits be zero
instead of ignoring them as it should.

This patch makes mmc_read_ext_csd() ignore the CARD_TYPE bits that are
reserved or not yet supported.  It also stops the function jumping to the
end as though an error occurred, when it is only warns that the CARD_TYPE
bits (that it does interpret) are invalid.

reiserfs: properly honor read-only devices

The reiserfs journal behaves inconsistently when determining whether to
allow a mount of a read-only device.

This is due to the use of the continue_replay variable to short circuit
the journal scanning.  If it's set, it's assumed that there are
transactions to replay, but there may not be.  If it's unset, it's assumed
that there aren't any, and that may not be the case either.

I've observed two failure cases:
1) Where a clean file system on a read-only device refuses to mount
2) Where a clean file system on a read-only device passes the
   optimization and then tries writing the journal header to update
   the latest mount id.

The former is easily observable by using a freshly created file system on
a read-only loopback device.

This patch moves the check into journal_read_transaction, where it can
bail out before it's about to replay a transaction.  That way it can go
through and skip transactions where appropriate, yet still refuse to mount
a file system with outstanding transactions.

reiserfs: fix oops while creating privroot with selinux enabled

Commit 57fe60df ("reiserfs: add atomic addition of selinux attributes

mounting a file system that didn't previously contain extended attributes
on a system using security.* xattrs.

The issue is that while creating the privroot during mount
reiserfs_security_init calls reiserfs_xattr_jcreate_nblocks which
dereferences the xattr root.  The xattr root doesn't exist, so we get an
oops.

exit: fix oops in sync_mm_rss

In 2.6.34-rc1, removing vhost_net module causes an oops in sync_mm_rss
(called from do_exit) when workqueue is destroyed.  This does not happen
on net-next, or with vhost on top of to 2.6.33.

The issue seems to be introduced by
34e55232e59f7b19050267a05ff1226e5cd122a5 ("mm: avoid false sharing of
mm_counter) which added sync_mm_rss() that is passed task->mm, and
dereferences it without checking.  If task is a kernel thread, mm might be
NULL.  I think this might also happen e.g.  with aio.

This patch fixes the oops by calling sync_mm_rss when task->mm is set to
NULL.  I also added BUG_ON to detect any other cases where counters get
incremented while mm is NULL.

The oops I observed looks like this:

mempolicy.

Upon remounting a tmpfs mount point with 'mpol=default' option, the mount

was on 2.6.27, but the problem exists in mainline 2.6.34-rc as well.  On

Documentation/volatile-considered-harmful.txt: correct cpu_relax() documentation

cpu_relax() is documented in volatile-considered-harmful.txt to be a
memory barrier.  However, everyone with the exception of Blackfin and
possibly ia64 defines cpu_relax() to be a compiler barrier.

Make the documentation reflect the general concensus.

Linus sayeth:

: I don't think it was ever the intention that it would be seen as anything
: but a compiler barrier, although it is obviously implied that it might
: well perform some per-architecture actions that have "memory barrier-like"
: semantics.
:
: After all, the whole and only point of the "cpu_relax()" thing is to tell
: the CPU that we're busy-looping on some event.
:
: And that "event" might be (and often is) about reading the same memory
: location over and over until it changes to what we want it to be.  So it's
: quite possible that on various architectures the "cpu_relax()" could be
: about making sure that such a tight loop on loads doesn't starve cache
: transactions, for example - and as such look a bit like a memory barrier
: from a CPU standpoint.
:
: But it's not meant to have any kind of architectural memory ordering
: semantics as far as the kernel is concerned - those must come from other
: sources.

[S390] system.h: Fix compile error for 1 and 2 byte cmpxchg

commit 024914477e15ef8b17f271ec47f1bb8a589f0806 "memcg: move charges of anonymous
swap" revealed that the 1 byte and 2 byte cmpxchg is currently broken:

arch/s390/include/asm/system.h: Assembler messages:

make[1]: *** [mm/page_cgroup.o] Error 1
make[1]: *** Waiting for unfinished jobs....

It turned out that commit 987bcdacb18a3adc2a48d85c9b005069c2f4dd7b ([S390] use
inline assembly contraints available with gcc 3.3.3) broke the inline assembly.

[S390] zcore: CPU registers are not saved under LPAR

To save the registers for all CPUs a sigp "store status" is done that
stores the registers to address absolute zero. To access storage at
absolute zero, normally the address of the prefix register of the
accessing CPU has to be used. This does not work when large pages are
active (currently only under LPAR). In order to fix that problem,
instead of memcpy memcpy_real is used, which switches to real mode
where prefixing works.

ALSA: cmipci: work around invalid PCM pointer

When the CMI8738 FRAME2 register is read, the chip sometimes (probably
when wrapping around) returns an invalid value that would be outside the
programmed DMA buffer. This leads to an inconsistent PCM pointer that is
likely to result in an underrun.

To work around this, read the register multiple times until we get a
valid value; the error state seems to be very short-lived.

libata-sff: fix spurious IRQ handling

Commit 27943620cbd960f710a385ff4a538e14ed3f1922 introduced spurious
IRQ handling but it has a race condition where valid completion can be
lost while trying to clear spurious IRQ leading to occassional command
timeouts.

This patch improves SFF interrupt handler such that

1. Once BMDMA HSM is stopped, the condition is never considered
   spurious.  As there's no way to resume stopped BMDMA HSM, if device
   status doesn't agree with BMDMA status, the only way out is
   aborting the command (otherwise, it will just end up timing out).

2. ap->ops->sff_check_status() can be safely called to clear spurious
   device IRQ as it atomically returns completion status but BMDMA IRQ
   status can't be cleared in safe way if command is in flight.  After
   a spurious IRQ, call ap->ops->sff_irq_clear() only if the
   respective device is idle and retry completion if
   sff_check_status() indicates command completion.

Please note that ata_piix uses bmdma_status for sff_irq_check() and #2
won't weaken spurious IRQ handling even with in-flight command because
if bmdma_status indicates IRQ pending but device status is not on
spurious check, the next IRQ handler invocation will abort the command
due to #1.

This fixes bko#15537.

ppc64 sys_ipc breakage in 2.6.34-rc2

I chased down a fail on ppc64 on 2.6.34-rc2 where an application that
uses shared memory was getting a SEGV.

Commit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 ("Add generic sys_ipc
wrapper") changed the second argument from an unsigned long to an int.
When we call shmget the system call wrappers for sys_ipc will sign
extend second (ie the size) which truncates it.  It took a while to
track down because the call succeeds and strace shows the untruncated
size :)

The patch below changes second from an int to an unsigned long which
fixes shmget on ppc64 (and I assume s390, sparc64 and mips64).
