Patch from Richard Purdie

Akita requires inbuilt kernel i2c support for its GPIOs. Add this
requirement to Kconfig and update the defconfig to match.

We must not call TLB maintainence operations with interrupts disabled,
otherwise we risk a lockup in the SMP IPI code.

This means that consistent_free() can not be called from a context with
IRQs disabled.  In addition, we must not hold the lock in consistent_free
when we call flush_tlb_kernel_range().  However, we must continue to
prevent consistent_alloc() from re-using the memory region until we've
finished tearing down the mapping and dealing with the TLB.

Therefore, leave the vm_region entry in the list, but mark it inactive
before dropping the lock and starting the tear-down process.  After the
mapping has been torn down, re-acquire the lock and remove the entry
from the list.

Patch from Daniel Jacobowitz

After delivering a signal (creating its stack frame) we must check for
additional pending unblocked signals before returning to userspace.
Otherwise signals may be delayed past the next syscall or reschedule.

Once that was fixed it became obvious that the ARM signal mask manipulation
was broken.  It was a little bit broken before the recent SA_NODEFER
changes, and then very broken after them.  We must block the requested
signals before starting the handler or the same signal can be delivered
again before the handler even gets a chance to run.

Unfortunately, later gcc versions error out when our get_user is passed

Document that the VMALLOC_END address must be aligned to 2MB since
it must align with a PGD boundary.

Allocate the vectors page early so that the flush_cache_all() later
will cause any dirty cache lines in the direct mapping will be safely
written back.

Move the flush_cache_all() to the second local_flush_cache_tlb() and
remove the now redundant first local_flush_cache_tlb().

Patch from Richard Purdie

Add a driver for the extra GPIOs found on the Sharp SL-C1000 (Akita).
These GPIOs are found on a Maxim MAX7310 I2C i/o expander chip. A
generic GPIO driver for the MAX7310 was attempted but this mini
driver is a much simpler and much more effective solution avoiding
several issues and complexity the generic driver had (as discussed
on LKML).

The platform device is required so the device parent can be set
correctly which ensures the device is one of the last to suspend
and first to resume. Whilst the i2c suspend/resume calls can be
influenced, nothing guarantees this is easlier/later than the
subsystems the gpios are used on which are all independent of i2c
(sound, irda, video/backlight etc.).
