Hi,
Here's few changes to x86 decompression code.
The first patch fixes build regression introduced by my recent patch. It only triggers when KASLR disabled and GCC version < 5. I haven't noticed this before.
The second patch is pure cosmetic change: give file with KASLR helpers a proper name.
The last two patches bring support of booting into 5-level paging mode if a bootloader put the kernel above 4G.
Patch 3/4 handles allocation of space for trampoline and gets it prepared. Patch 4/4 gets trampoline used.
Please review and consider applying.
Kirill A. Shutemov (4): x86/boot/compressed/64: Fix build with GCC < 5 x86/boot/compressed/64: Rename pagetable.c to kaslr_64.c x86/boot/compressed/64: Introduce place_trampoline() x86/boot/compressed/64: Handle 5-level paging boot if kernel is above 4G
