The flexible array in the USBH platform data is not safe to copy. The
compiler will not allocate any extra memory for the non-init platform
data structure (in the *_devices.c files) since it isn't given any
defaults at compile time. When the probe function attempts to address
that array, it will actually attempt to access data in an adjacent
structure.
Since there are currently no (known) implementations of the at91 USBH
IP with more than 2 vbus pins, I am capping the value at 2. If somebody
tries to assign more, then the compiler will produce a warning.

Some cards are not able to calculate a valid CRC16 value
for CID and CSD reads (CRC for 512 byte data blocks is OK).
By moving the CRC enable after the read of CID and CSD, these

Spurious IRQs seen on MMC after 2.6.29. Flush posted write in IRQ
handler.
The interrupt line is released by clearing the error status bits
in the MMCHS_STAT register, which must occur before the interrupt

the posted write.

Now that we have a distinction between WRITE_SYNC and WRITE_SYNC_PLUG,
use WRITE_SYNC_PLUG in __block_write_full_page() to avoid unplugging
the block device I/O queue between each page that gets flushed out.
Otherwise, when we run sync() or fsync() and we need to write out a
large number of pages, the block device queue will get unplugged
between for every page that is flushed out, which will be a pretty
serious performance regression caused by commit a64c8610.

Add support for Always Running APIC timer, CPUID_0x6_EAX_Bit2.
This bit means the APIC timer continues to run even when CPU is
in deep C-states.
The advantage is that we can use LAPIC timer on these CPUs
always, and there is no need for "slow to read and program"
external timers (HPET/PIT) and the timer broadcast logic
and related code in C-state entry and exit.

> BUG: unable to handle kernel NULL pointer dereference at (null)
What happens is that the battery module's init sections are being freed
before the async callback (which was marked __init) has run. This theory
is supported by the fact that the bad RIP value is a vmalloc address.
The immediate fix is to make this a non-init call.
(A better long-term fix is of course to wait with init-section unloading
until a module's async initcalls have been run, which would allow us to
discard this function which is still only run once, after all. Perhaps a
new async_initcall() function for the async/module API, if this is needed
for other modules in the future?)

The code that enables branch tracing for all (non-constant) branches
plays games with the preprocessor and #define's the C 'if ()' construct
to do tracing.
That's all fine, but it fails for some unusual but valid C code that is
sometimes used in macros, notably by the intel-iommu code:
if (i=drhd->iommu, drhd->ignored) ..
because now the preprocessor complains about multiple arguments to the
'if' macro.
So make the macro expansion of this particularly horrid trick use
varargs, and handle the case of comma-expressions in if-statements. Use
another macro to do it cleanly in just one place.
This replaces a patch by David (and acked by Steven) that did this all
inside that one already-too-horrid macro.
