Merge tag 'x86-boot-2023-06-26' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 boot updates from Thomas Gleixner: "Initialize FPU late. Right now FPU is initialized very early during boot. There is no real requirement to do so. The only requirement is to have it done before alternatives are patched. That's done in check_bugs() which does way more than what the function name suggests. So first rename check_bugs() to arch_cpu_finalize_init() which makes it clear what this is about. Move the invocation of arch_cpu_finalize_init() earlier in start_kernel() as it has to be done before fork_init() which needs to know the FPU register buffer size. With those prerequisites the FPU initialization can be moved into arch_cpu_finalize_init(), which removes it from the early and fragile part of the x86 bringup" * tag 'x86-boot-2023-06-26' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mem_encrypt: Unbreak the AMD_MEM_ENCRYPT=n build x86/fpu: Move FPU initialization into arch_cpu_finalize_init() x86/fpu: Mark init functions __init x86/fpu: Remove cpuinfo argument from init functions x86/init: Initialize signal frame size late init, x86: Move mem_encrypt_init() into arch_cpu_finalize_init() init: Invoke arch_cpu_finalize_init() earlier init: Remove check_bugs() leftovers um/cpu: Switch to arch_cpu_finalize_init() sparc/cpu: Switch to arch_cpu_finalize_init() sh/cpu: Switch to arch_cpu_finalize_init() mips/cpu: Switch to arch_cpu_finalize_init() m68k/cpu: Switch to arch_cpu_finalize_init() loongarch/cpu: Switch to arch_cpu_finalize_init() ia64/cpu: Switch to arch_cpu_finalize_init() ARM: cpu: Switch to arch_cpu_finalize_init() x86/cpu: Switch to arch_cpu_finalize_init() init: Provide arch_cpu_finalize_init()
