#     Merge tag 'x86-boot-2024-03-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 boot updates from Ingo Molnar:
#     
#      - Continuing work by Ard Biesheuvel to improve the x86 early startup
#        code, with the long-term goal to make it position independent:
#     
#           - Get rid of early accesses to global objects, either by moving
#             them to the stack, deferring the access until later, or dropping
#             the globals entirely
#     
#           - Move all code that runs early via the 1:1 mapping into
#             .head.text, and move code that does not out of it, so that build
#             time checks can be added later to ensure that no inadvertent
#             absolute references were emitted into code that does not
#             tolerate them
#     
#           - Remove fixup_pointer() and occurrences of __pa_symbol(), which
#             rely on the compiler emitting absolute references, which is not
#             guaranteed
#     
#      - Improve the early console code
#     
#      - Add early console message about ignored NMIs, so that users are at
#        least warned about their existence - even if we cannot do anything
#        about them
#     
#      - Improve the kexec code's kernel load address handling
#     
#      - Enable more X86S (simplified x86) bits
#     
#      - Simplify early boot GDT handling
#     
#      - Micro-optimize the boot code a bit
#     
#      - Misc cleanups
