Subject: [GIT PULL] x86/boot changes for v6.7

Linus,

Please pull the latest x86/boot git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-boot-2023-10-28

   # HEAD: 50dcc2e0d62e3c4a54f39673c4dc3dcde7c74d52 x86/boot: efistub: Assign global boot_params variable

MERGE NOTE:

 - Pulling this tree will generate a conflict in 
   drivers/firmware/efi/libstub/x86-stub.c, due to a fix we wanted upstream 
   without related cleanups, which is resolved by picking this resolution:

        boot_params_ptr = boot_params;

Changes to the x86 boot code in v6.7:

 - Rework PE header generation, primarily to generate a modern, 4k aligned
   kernel image view with narrower W^X permissions.

 - Further refine init-lifetime annotations

 - Misc cleanups & fixes

 Thanks,

	Ingo
