Subject: [PATCH 0/6] kexec: put bzImage and ramdisk above 4G for x86 64bit
Date: Sun, 18 Nov 2012 19:02:25 -0800 [thread overview]
Message-ID: <1353294151-32133-1-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <878v9zp55t.fsf@xmission.com>
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.
-v2: remove mem64-min/mem64-max
add purgartory changes from Eric, that make it relocatable
put command line above 4g.
Eric W. Biederman (1):
kexec, x86: Make x64_64 purgatory relocatable above 4G
Yinghai Lu (5):
kexec, x86: add boot header member for version 2.12
kexec: don't die during buffer finding
kexec, x86: put ramdisk high for 64bit bzImage
kexec, x86: set ext_cmd_line_ptr when boot_param is put high
kexec, x86_64: put 64bit bzImage high
