[PATCH] Fix sparse parse error in lppaca.h

sparse can't parse a struct definition in include/asm-powerpc/lppaca.h,
even though gcc can accept it.  The form looks like this:

        struct __attribute__((whatever)) foo { };

An equivalent that both gcc and sparse can handle is

        struct foo { } __attribute__((whatever));

This is the only definition of this type in the tree, and fixing it is
easier than fixing sparse.

[ Side note: fixing sparse wouldn't be hard, but the "attribute at the
  end" version is the canonical one, and the one that makes sense. So
  let's just fix the kernel instead. Luc Van Oostenryck already sent
  out a sparse patch to the sparse mailing list in case anybody cares.

[SPARC64]: Eliminate race condition reading Hummingbird STICK register

Ensure a consistent value is read from the STICK register by ensuring
that both high and low are read without high changing due to a roll
over of the low register.

Various Debian/SPARC users (myself include) have noticed problems with
Hummingbird based systems. The symptoms are that the system time is
seen to jump forward 3 days, 6 hours, 11 minutes give or take a few
seconds. In many cases the system then hangs some time afterwards.

I've spotted a race condition in the code to read the STICK register.
I could not work out why 3d, 6h, 11m is important but guess that it is
due to the 2^32 jump of STICK (forwards on one read and then the next
read will seem to be backwards) during a timer interrupt. I'm guessing
that a change of -2^32 will get converted to a large unsigned
increment after the arithmetic manipulation between STICK,
nanoseconds, jiffies etc.

I did a test where I modified __hbird_read_stick to artificially
inject rollover faults forcefully every few seconds. With this I saw
the clock jump over 6 times in 12 hours compared to once every month
or so.

[IPV4]: rt_cache_stat can be statically defined

Using __get_cpu_var(obj) is slightly faster than per_cpu_ptr(obj,
raw_smp_processor_id()).

1) Smaller code and memory use
For static and small objects, DEFINE_PER_CPU(type, object) is preferred over a
alloc_percpu() : Better and smaller code to access them, and no extra memory
(storing the pointer, and the percpu array of pointers)

x86_64 code before patch

mov    1237577(%rip),%rax        # ffffffff803e5990 <rt_cache_stat>
not    %rax  # part of per_cpu machinery
mov    %gs:0x3c,%edx # get cpu number
movslq %edx,%rdx # extend 32 bits cpu number to 64 bits
mov    (%rax,%rdx,8),%rax # get the pointer for this cpu
incl   0x38(%rax)

x86_64 code after patch

mov    $per_cpu__rt_cache_stat,%rdx
mov    %gs:0x48,%rax # get percpu data offset
incl   0x38(%rax,%rdx,1)

2) False sharing avoidance for SMP :
For a small NR_CPUS, the array of per cpu pointers allocated in alloc_percpu()
can be <= 32 bytes. This let slab code gives a part of a cache line. If the
other part of this 64 bytes (or 128 bytes) cache line is used by a mostly
written object, we can have false sharing and expensive per_cpu_ptr() operations.

Size of rt_cache_stat is 64 bytes, so this patch is not a danger of a too big
increase of bss (in UP mode) or static per_cpu data for SMP
(PERCPU_ENOUGH_ROOM is currently 32768 bytes)

[PATCH] fuse: fix bitfield race

Fix race in setting bitfields of fuse_conn.  Spotted by Andrew Morton.

The two fields ->connected and ->mounted were always changed with the
fuse_lock held.  But other bitfields in the same structure were changed
without the lock.  In theory this could lead to losing the assignment of
even the ones under lock.  The chosen solution is to change these two
fields to be a full unsigned type.  The other bitfields aren't "important"
enough to warrant the extra complexity of full locking or changing them to
bitops.

For all bitfields document why they are safe wrt. concurrent
assignments.

Also make the initialization of the 'num_waiting' atomic counter explicit.

[PATCH] fuse: add connection aborting

Add ability to abort a filesystem connection.

With the introduction of asynchronous reads, the ability to interrupt any
request is not enough to dissolve deadlocks, since now waiting for the request
completion (page unlocked) is independent of the actual request, so in a
deadlock all threads will be uninterruptible.

The solution is to make it possible to abort all requests, even those
currently undergoing I/O to/from userspace. The natural interface for this is
'mount -f mountpoint', but that only works as long as the filesystem is
attached. So also add an 'abort' attribute to the sysfs view of the
connection.

[PATCH] fuse: fuse_copy_finish() order fix

fuse_copy_finish() must be called before request_end(), since the later might
sleep, and no sleeping is allowed between fuse_copy_one() and
fuse_copy_finish() because of kmap_atomic()/kunmap_atomic() used in them.

[PATCH] partitions: Read Rio Karma partition table

The Rio Karma portable MP3 player has its own proprietary partition table.

The partition layout is similar to a DOS boot sector but it begins at a
different offset and uses a different magic number (0xAB56 instead of
0xAA55). Add support for it to enable mounting the device.

[PATCH] sh: Move CPU subtype configuration to its own Kconfig

Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat.

Given that, this moves all of that in to its own arch/sh/mm/Kconfig. Things
like cache configuration are also moved to this new location.

This also adds support for strict CPU tuning on newer cores, which requires
the addition of as-option.

[PATCH] sh: Simple timer framework

[PATCH] sh: Simplistic clock framework

This adds a relatively simplistic clock framework for sh. The initial goal
behind this is to clean up the arch/sh/kernel/time.c mess and to get the CPU
subtype-specific frequency setting and calculation code moved somewhere more
sensible.

This only deals with the core clocks at the moment, though it's trivial for
other drivers to define their own clocks as desired.

[PATCH] sh: I/O routine cleanups and ioremap() overhaul

This introduces a few changes in the way that the I/O routines are defined on
SH, specifically so that things like the iomap API properly wrap through the
machvec for board-specific quirks.

In addition to this, the old p3_ioremap() work is converted to a more generic
__ioremap() that will map through the PMB if it's available, or fall back on
page tables for everything else.

An alpha-like IO_CONCAT is also added so we can start to clean up the
board-specific io.h mess, which will be handled in board update patches..

[PATCH] sh: IRQ handler updates

This moves the various IRQ controller drivers into a new subdirectory, and
also extends the INTC2 IRQ handler to also deal with SH7760 and SH7780
interrupts, rather than just ST-40.

The old CONFIG_SH_GENERIC has also been removed from the IRQ definitions, as
new ports are expected to be based off of CONFIG_SH_UNKNOWN. Since there are
plenty of incompatible machvecs, CONFIG_SH_GENERIC doesn't make sense anymore.

[PATCH] sh: DMA updates

This extends the current SH DMA API somewhat to support a proper virtual
channel abstraction, and also works to represent this through the driver model
by giving each DMAC its own platform device.

There's also a few other minor changes to support a few new CPU subtypes, and
make TEI generation for the SH DMAC configurable.

[PATCH] sh: consolidate hp620/hp680/hp690 targets into hp6xx

Most of the reasons for keeping these separate before was due to hp690
discontig, and since we have a workaround for that now (abusing some shadow
space so everything is magically contiguous), there's no reason to keep the
targets separate.
