Marc Zyngier	cfc5180e5a	arm64: move FP-SIMD save/restore code to a macro ... In order to be able to reuse the save-restore code in KVM, move it to a pair of macros, similar to what the 32bit code does.

Catalin Marinas	53631b54c8	arm64: Floating point and SIMD ... This patch adds support for FP/ASIMD register bank saving and restoring during context switch and FP exception handling to generate SIGFPE. There are 32 128-bit registers and the context switching is currently done non-lazily. Benchmarks on real hardware are required before implementing lazy FP state saving/restoring.
