Here's few changes to x86 decompression code.
The first patch is pure cosmetic change: it gives file with KASLR helpers a proper name.
The last three patches bring support of booting into 5-level paging mode if a bootloader put the kernel above 4G.
Patch 2/4 Renames l5_paging_required() into paging_prepare() and change interface of the function. Patch 3/4 Handles allocation of space for trampoline and gets it prepared. Patch 4/4 Gets trampoline used.
Kirill A. Shutemov (4): x86/boot/compressed/64: Rename pagetable.c to kaslr_64.c x86/boot/compressed/64: Introduce paging_prepare() x86/boot/compressed/64: Prepare trampoline memory x86/boot/compressed/64: Handle 5-level paging boot if kernel is above 4G
