This series fixes two regressions: a boot failure on AMD K7 and a performance regression on everything.
I did a double-take here -- the regressions were reported by different people, both named Krzysztof :) Changes from v2: - Tidy up the if statements (Sean) - Changelog and comment improvements (Boris) Changes from v1: - Fix MMX better -- MMX really does need FNINIT. - Improve the EFI code. - Rename the KFPU constants. - Changelog improvements. Andy Lutomirski (4): x86/fpu: Add kernel_fpu_begin_mask() to selectively initialize state x86/mmx: Use KFPU_387 for MMX string operations x86/fpu: Make the EFI FPU calling convention explicit x86/fpu/64: Don't FNINIT in kernel_fpu_begin() arch/x86/include/asm/efi.h | 24 ++++++++++++++++++++---- arch/x86/include/asm/fpu/api.h | 27 +++++++++++++++++++++++++-- arch/x86/kernel/fpu/core.c | 9 +++++---- arch/x86/lib/mmx_32.c | 20 +++++++++++++++----- arch/x86/platform/efi/efi_64.c | 4 ++-- 5 files changed, 67 insertions(+), 17 deletions(-) -- 2.29.2
