If anyone has any objections, please let me know. ------------------ From: Huacai Chen [ Upstream commit 9b56c3659a7e5d930ab3c07ea74cc46af65b6d20 ] After commit 35ebc4de105989034f12 ("xor: remove macro abuse for XOR implementation registrations"), using "simd=128" to limit SIMD on a platform with 256bit SIMD instructions causes a boot failure. Because cpu_final_simd() is called with arch_initcall() now, which is after xor_init(), LASX flavors are selected but not workable. Call cpu_final_simd() with pure_initcall() which is before xor_init().
