Shutemov" 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 two patches bring support of booting into 5-level paging mode if a bootloader put the kernel above 4G. Patch 2/3 handles allocation of space for trampoline and gets it prepared. Patch 3/3 gets trampoline used. Kirill A. Shutemov (3): 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 arch/x86/boot/compressed/Makefile | 2 +- arch/x86/boot/compressed/head_64.S | 138 +++++++++++++-------- .../boot/compressed/{pagetable.c => kaslr_64.c} | 0 arch/x86/boot/compressed/pgtable.h | 18 +++ arch/x86/boot/compressed/pgtable_64.c | 61 +++++++-- 5 files changed, 153 insertions(+), 66 deletions(-) rename arch/x86/boot/compressed/{pagetable.c => kaslr_64.c} (100%) create mode 100644 arch/x86/boot/compressed/pgtable.h -- 2.15.0 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
