   # HEAD: b25eb5f5e419b81f124d5ba2abaaacf1948fb97e x86/kexec: Add relocate_kernel() debugging support: Load a GDT

Updates to the x86 boot code for the v6.15 cycle:

  - Memblock setup and other early boot code cleanups (Mike Rapoport)
  - Export e820_table_kexec[] to sysfs (Dave Young)
  - Baby steps of adding relocate_kernel() debugging support (David Woodhouse)
  - Replace open-coded parity calculation with parity8() (Kuan-Wei Chiu)
  - Move the LA57 trampoline to separate source file (Ard Biesheuvel)
  - Misc micro-optimizations (Uros Bizjak)
  - Drop obsolete E820_TYPE_RESERVED_KERN and related code (Mike Rapoport)

 Thanks,

	Ingo
