Subject: [PATCHv2 0/4] x86: 5-level related changes into decompression code
Date: Sat, 11 Nov 2017 01:06:41 +0300 [thread overview]
Message-ID: <20171110220645.59944-1-kirill.shutemov@linux.intel.com> (raw)
Hi Ingo,
Here's updated changes that prepare the code to boot-time switching between
paging modes and handle booting in 5-level mode when bootloader put kernel
image above 4G, but haven't enabled 5-level paging for us.
I've updated patches based on your feedback.
Please review and consider applying.
Kirill A. Shutemov (4):
x86/boot/compressed/64: Rename pagetable.c to kaslr_64.c
x86/boot/compressed/64: Detect and handle 5-level paging at boot-time
x86/boot/compressed/64: Introduce place_trampoline()
x86/boot/compressed/64: Handle 5-level paging boot if kernel is above
