Patch fixes a build problem with CONFIG_X86_VSMP. The vSMP bits probably
gathered some fuzz on its way to mainline, and safe_halt() which was outside
the #endif (CONFIG_X86_VSMP) somehow got inside the !CONFIG_X86_VSMP condition,
hence being undefined and breaking CONFIG_X86_VSMP builds. Patch takes
safe_halt() and halt() macros out of the #endif

Another try at this.
For 32bit follow the 32bit implementation from Ingo -
mappings are growing down from the end of stack now
and vary randomly by 1GB.
Randomized mappings for 64bit just vary the normal mmap break
by 1TB. I didn't bother implementing full flex mmap for 64bit
because it shouldn't be needed there.

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.

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..

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.

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.

arm26 currently has a 256 kB THREAD_SIZE (sic).
Looking at the comment in the code, this seems to be based on a
misunderstanding.
The comment says:
this needs attention (see kernel/fork.c which gets a nice div by zero if
this is lower than 8*32768
kernel/fork.c does:
max_threads = mempages / (8 * THREAD_SIZE / PAGE_SIZE)
Therefore, a division by 0 is impossible for all reasonable cases with
THREAD_SIZE >= PAGE_SIZE.
Since the minimum PAGE_SIZE Linux uses on the arm26 architecture is 16k,
PAGE_SIZE should be sufficient for THREAD_SIZE.

tuners that need this.
- Moved MSP_SET_MATRIX to v4l2-common.h
- Fix typos and integer overflows in tea5767.c
- Split old freq field into a tv_freq and a radio_freq. Prevents
that a radio tuner is initialized with a tv frequency or vice versa.
- When switching to radio mode initialize the tuner with the last
used radio frequency (this was already done for the TV mode).
As a result of these changes the tuner module now remembers the
last set radio and TV frequencies, which is what you would expect
to happen.
- Move out of range frequencies to the closest valid frequency as per
v4l2 API spec.
- Fix incorrect initial radio frequency (multiplier is 16000, not 16)
- Add boundary check for out of range frequencies.
- Use new flag to check if the order of the CB and freq. depends on
the last set frequency. That is needed for some tuners or you can
get static as a result. The flag is added for those tuners where I know
that the datasheet indicates that this is necessary.
- For this new check use the last set div value, not the last frequency
as radio frequencies are always much higher due to the 16000 multiplier.

This makes it possible to build kernels for PReP and/or CHRP
with ARCH=ppc by removing the (non-building) powermac support.
It's now also possible to select PReP and CHRP independently.
Powermac users should now build with ARCH=powerpc instead of
ARCH=ppc. (This does mean that it is no longer possible to
build a 32-bit kernel for a G5.)

Mark a number of functions as 'must inline'. The functions affected by this
patch need to be inlined because they use knowledge that their arguments are
constant so that most of the function optimizes away. At this point this
patch does not change behavior, it's for documentation only (and for future
patches in the inline series)

This patch is the first in a series that tries to optimize the kernel in terms
of size (and thus cache behavior, both cpu and pagecache).
This first patch changes __always_inline to be a forced inline instead of the
"regular" inline it was on everything except alpha. This forced inline
matches the intention of the define better as a matter of documentation.
There is no change in behavior by this patch, since "inline" currently is
mapped to a forced inline anyway.

The problem, reported in:
http://bugzilla.kernel.org/show_bug.cgi?id=5859
and by various other email messages and lkml posts is that the cpuset hook
in the oom (out of memory) code can try to take a cpuset semaphore while
holding the tasklist_lock (a spinlock).
One must not sleep while holding a spinlock.
The fix seems easy enough - move the cpuset semaphore region outside the
tasklist_lock region.
This required a few lines of mechanism to implement. The oom code where
the locking needs to be changed does not have access to the cpuset locks,
which are internal to kernel/cpuset.c only. So I provided a couple more
cpuset interface routines, available to the rest of the kernel, which
simple take and drop the lock needed here (cpusets callback_sem).

Anything that writes into a tmpfs filesystem is liable to disproportionately
decrease the available memory on a particular node. Since there's no telling
what sort of application (e.g. dd/cp/cat) might be dropping large files
there, this lets the admin choose the appropriate default behavior for their
site's situation.
Introduce a tmpfs mount option which allows specifying a memory policy and
a second option to specify the nodelist for that policy. With the default
policy, tmpfs will behave as it does today. This patch adds support for
preferred, bind, and interleave policies.
The default policy will cause pages to be added to tmpfs files on the node
which is doing the writing. Some jobs expect a single process to create
and manage the tmpfs files. This results in a node which has a
significantly reduced number of free pages.
With this patch, the administrator can specify the policy and nodes for
that policy where they would prefer allocations.
This patch was originally written by Brent Casavant and Hugh Dickins. I
added support for the bind and preferred policies and the mpol_nodelist
mount option.
