I think the regression is related with the commit, that commit
b81fac906a8f changes the FPU init order, and cause the 'X86_FEATURE_OSXSAVE'
missed the cpu capability setup, thus all later check of
boot_cpu_has(X86_FEATURE_OSXSAVE) will return false.

arch_cpu_finalize_init
identify_boot_cpu
identify_cpu
generic_identify
get_cpu_cap --> setup cpu capability
...
fpu__init_cpu
fpu__init_cpu_xstate
cr4_set_bits(X86_CR4_OSXSAVE);

Many security moduels in arch/x86 have dependency on X86_FEATURE_OSXSAVE,
and will fail to load later. While this 'af-alg' case involves secuirty
operation and tries to load those modules but fail, which cause the
regression.

Setting the 'OSXSVAE' feature bit after OSXSAVE enabling can restore
the regression, like the below RFC patch. pls help to review, thanks!

Subject: [PATCH RFC] x86/fpu: set X86_FEATURE_OSXSAVE feature after enabling
OSXSAVE in CR4

Commit b81fac906a8f ("x86/fpu: Move FPU initialization into
arch_cpu_finalize_init()" optimized the FPU init order, and moves the
CR4_OSXSAVE enabling into a later flace.

arch_cpu_finalize_init
identify_boot_cpu
identify_cpu
generic_identify
get_cpu_cap --> setup cpu capability
...
fpu__init_cpu
fpu__init_cpu_xstate
cr4_set_bits(X86_CR4_OSXSAVE);

This makes 'X86_FEATURE_OSXSAVE' missed in cpu capability setup. Many
security module like 'camellia_aesni_avx_x86_64' depends on this feature
and will fail to load after the commit. 0Day caught a 34% regression
in stress-ng's 'af-alg' test case [1].
