https://lists.ozlabs.org/pipermail/linuxppc-dev/2016-January/138054.html
Changes in V3:
Addressed review comments from Michael Neuling
- Made commit message in 4/9 better reflect the patch
- Removed overuse of #ifdef blocks and redundant condition in 5/9
- Split 6/8 in two to better prepare for 7,8,9
- Removed #ifdefs in 6/9
Changes in V4:
- Addressed non ABI compliant ASM macros in 1/9
- Fixed build breakage due to changing #ifdefs in V3 (6/9)
- Reordered some conditions in if statements
Cyril Bur (9):
selftests/powerpc: Test the preservation of FPU and VMX regs across
syscall
selftests/powerpc: Test preservation of FPU and VMX regs across
preemption
selftests/powerpc: Test FPU and VMX regs in signal ucontext
powerpc: Explicitly disable math features when copying thread
powerpc: Restore FPU/VEC/VSX if previously used
powerpc: Prepare for splitting giveup_{fpu,altivec,vsx} in two
powerpc: Add the ability to save FPU without giving it up
powerpc: Add the ability to save Altivec without giving it up
powerpc: Add the ability to save VSX without giving it up
