  target-arm: Factor out handling of SRS instruction

Factor out the handling of the SRS instruction rather than
duplicating it between the Thumb and ARM decoders. This in
passing fixes two bugs in the Thumb decoder's SRS handling
which didn't exist in the ARM decoder:
 * (LP:1079080) storing CPSR rather than SPSR (fixed in the
   ARM decoder in commit c67b6b71 in 2009)
 * failing to free the 'addr' TCG temp in the writeback case

ARM Linux (like x86-64 Linux) can use transparent hugepages for
KVM if memory blocks are 2MiB aligned; set QEMU_VMALLOC_ALIGN
accordingly.

  linux-headers: resync from mainline to add ARM KVM headers

Resync QEMU's copy of the Linux kernel headers from
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit 2ef14f4. This adds the ARM KVM headers, since ARM KVM
support has just hit mainline via Russell's ARM tree.

This is not a pure sync -- I have removed by hand some changes
that would have reverted updates for s390x and ppc which have not
yet hit mainline.

  target-arm: Drop CPUARMState* argument from bank_number()

Drop the CPUARMState* argument from bank_number(), since we only
use it for passing to cpu_abort(). Use hw_error() instead.
This avoids propagating further interfaces using env pointers.

In the long term this function's callers need auditing to fix
problems where badly behaved guests can pass invalid bank numbers.

  ARM KVM: save and load VFP registers from kernel

Add support for saving and restoring VFP register state from the
kernel. This includes a check that the KVM-created CPU has full
VFP support (as the TCG Cortex-A15 model always does), since for
the moment ARM QEMU doesn't have any way to tweak optional features
on created CPUs.

  target-arm: Use MemoryListener to identify GIC base address for KVM

When using an in-kernel GIC with KVM, we need to tell the kernel where
the GIC's memory mapped registers live. Do this by registering a
MemoryListener which tracks where the board model maps the A15's
private peripherals, so we can finish the GIC initialisation
when the GIC is actually mapped.
