Now that eagerfpu= is gone, remove it from the docs. Whoops.
Fixes: ca6938a1cd8a ("x86/fpu: Hard-disable lazy FPU mode")

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
