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,
