Subject: [PATCH v3 0/7] x86, boot: clean up kasl
Date: Sat, 7 Mar 2015 14:07:14 -0800 [thread overview]
Message-ID: <1425766041-6551-1-git-send-email-yinghai@kernel.org> (raw)
First 3 patches make ZO (arch/x86/boot/compressed/vmlinux) data region is not
overwritten by VO (vmlinux) after decompress. So could pass data from ZO to VO.
The 4th one is fixing kaslr_enabled accessing. Old code is using address
as value wrongly.
Last 3 patches are the base for kaslr supporting kernel above 4G.
create new ident mapping for kasl 64bit, so we can cover
above 4G random kernel base, also don't need to track pagetable
for 64bit bootloader (patched grub2 or kexec).
that will make mem_avoid handling simple.
Please put first 4 patches into tip/x86/urgent to v4.0
Last 3 patches should go to tip/x86/kasl and to v4.1, but you may need to
pull x86/urgent to x86/kasl, as them depends on first 4 patches.
He could rebase his patches about kasl on top those patches.
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-4.0-rc2-aslr
Thanks
Yinghai Lu
