Subject: [PATCH 0/4] x86/boot/compressed/64: Switch between paging modes using trampoline
Date: Mon, 12 Mar 2018 13:02:42 +0300 [thread overview]
Message-ID: <20180312100246.89175-1-kirill.shutemov@linux.intel.com> (raw)
This patchset changes kernel decompression code to use trampoline to
switch between paging modes.
The patchset is replacement for previously reverted patch "Handle 5-level
paging boot if kernel is above 4G".
Please review and consider applying.
Kirill A. Shutemov (4):
x86/boot/compressed/64: Make sure we have 32-bit code segment
x86/boot/compressed/64: Use stack from trampoline memory
x86/boot/compressed/64: Use page table in trampoline memory
x86/boot/compressed/64: Handle 5-level paging boot if kernel is above 4G
