Our CPUID-less FPU detection code was terminally broken and, as far as I can tell, it's been broken for a long, long time. This series tries to improve the situation.
Changes from v1: - Whitespace fixes - Prettify the FPU probing code (Borislav) - Improve logging (Borislav) Andy Lutomirski (5): x86/cpu: Factor out application of forced cpu caps x86/cpu: Re-apply forced caps every time cpu caps are re-read x86/fpu: Fix "x86/fpu: Legacy x87 FPU detected" message x86/fpu: Fix CPUID-less FPU detection x86/fpu: Fix the "Giving up, no FPU found" test Borislav Petkov (1): x86/cpu: Add X86_FEATURE_CPUID arch/x86/include/asm/cpufeatures.h | 2 +- arch/x86/kernel/cpu/common.c | 34 +++++++++++++++++++++++----------- arch/x86/kernel/fpu/init.c | 31 +++++++++++++++++-------------- arch/x86/kernel/fpu/xstate.c | 8 +++++++- 4 files changed, 48 insertions(+), 27 deletions(-) -- 2.9.3
