Merge tag 'x86-build-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 build updates from Ingo Molnar:
- Use -fpic to build the kexec 'purgatory' (the self-contained
code that runs between two kernels)
- Clean up vmlinux.lds.S generation
- Simplify the X86_EXTENDED_PLATFORM section of the x86 Kconfig
- Misc cleanups & fixes
