Pull misc x86 fixes from Ingo Molnar:
- Limit AMD microcode Entrysign sha256 signature checking to
known CPU generations
- Disable AMD RDSEED32 on certain Zen5 CPUs that have a
microcode version before when the microcode-based fix was
issued for the AMD-SB-7055 erratum
- Fix FPU AMD XFD state synchronization on signal delivery
- Fix (work around) a SSE4a-disassembly related build failure
on X86_NATIVE_CPU=y builds
- Extend the AMD Zen6 model space with a new range of models
- Fix <asm/intel-family.h> CPU model comments
- Fix the CONFIG_CFI=y and CONFIG_LTO_CLANG_FULL=y build, which
was unhappy due to missing kCFI type annotations of clear_page()
variants
