Subject: [patch 0/3] [x86] Fix crashkernel reservation on NUMA machines
Date: Sun, 08 Jun 2008 15:46:28 +0200	[thread overview]
Message-ID: <20080608134628.757299158@halley.suse.de> (raw)

This patch series fixes the crashkernel reservation on NUMA machine. The
regression was discovered by Dave Anderson <anderson@redhat.com>.

The background is that on NUMA machines, reserve_bootmem_generic() is required
instead of reserve_bootmem(). To achieve that, it's necessary to make a few
API changes.

The patches are against latest linux-2.6 git. They should still go into 2.6.26
since it's only bug fixing. For 2.6.27, we should unify crashkernel reservation
for i386 and x86-64.

Tested on both i386 and x86-64. Compilation was tested with both kexec disabled
and enabled. The change is x86 only, so no need to test on other architectures.
