This is version 2 of the kernel mode NEON patch set.
Changes since v1:
- changed the order of the patches, so kernel_neon_begin() does not
appear before the required fixes are in place
- don't use might_sleep() to enforce that kernel_neon_begin() should
not be called from interrupt context, as it also prevents it from
being called with preemption disabled, which is perfectly acceptable
- prefer inc_preempt_count() over preempt_disable() so sleeping after
calling kernel_neon_begin() gets flagged even with kernel preemption
disabled in Kconfig
- made the RAID6 patch suitable for both arm and arm64
Ard Biesheuvel (5):
ARM: move VFP init to an earlier boot stage
ARM: be strict about FP exceptions in kernel mode
ARM: add support for kernel mode NEON
ARM: crypto: add NEON accelerated XOR implementation
lib/raid6: add ARM-NEON accelerated syndrome calculation
