Could we make the eagerfpu removal more exhaustive please:
triton:~/tip> git grep -i eagerfpu Documentation/kernel-parameters.txt: eagerfpu= [X86] Documentation/kernel-parameters.txt: enables eagerfpu restore for xsaveopt. arch/x86/include/asm/cpufeatures.h:/* free, was #define X86_FEATURE_EAGER_FPU ( 3*32+29) * "eagerfpu" Non lazy FPU restore */ arch/x86/include/asm/fpu/types.h: * or not. On such CPUs we activate the non-lazy ('eagerfpu') arch/x86/mm/pkeys.c: * using eagerfpu mode makes this possible. tools/arch/x86/include/asm/cpufeatures.h:#define X86_FEATURE_EAGER_FPU ( 3*32+29) /* "eagerfpu" Non lazy FPU restore */
Thanks,
Ingo
