Subject: [PATCH v3 0/4] kexec: put bzImage and ramdisk above 4G for x86 64bit
Date: Tue, 20 Nov 2012 23:31:34 -0800 [thread overview]
Message-ID: <1353483098-14883-1-git-send-email-yinghai@kernel.org> (raw)
Now we have limit kdump reserved under 896M, because kexec has the limitation.
and also bzImage need to stay under 4g.
kernel parts changes could be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-boot
here patches are for kexec tools to load bzImage and ramdisk high acccording
to new added boot header fields.
-v3: address review from Eric to use locate_hole at first.
use xloadflags instead.
Yinghai Lu (4):
kexec, x86: add boot header member for version 2.12
kexec, x86: put ramdisk high for 64bit bzImage
kexec, x86: set ext_cmd_line_ptr when boot_param is above 4g
kexec, x86_64: Load bzImage64 above 4G
