[PATCH] 2.6.8-rc1-kexec1 (ppc & x86)

From:  ebiederm@xmission.com (Eric W. Biederman)
To:  fastboot@osdl.org
Subject:  [ANNOUNCE] [PATCH] 2.6.8-rc1-kexec1 (ppc & x86)
Date:  15 Jul 2004 00:12:52 -0600

I finally found some time to work on kexec again.
I have taken the time to break the patches apart again, because
with everything all in one patch things get unmaintainable.

But I have also lumped everything together in one big patch to make testing
easier.

While doing this I found a bug where I was not putting IOAPIC into
virtual wire mode where appropriate.  This allows kexec to work on Opterons
and other affected systems.

The files are available at:
lynx http://www.xmission.com/~ebiederm/files/kexec/2.6.8-rc1-kexec1


The first hunk of patches are essentially generic fixes to the boot
process.  That should be safe to apply in general.

i8259-shutdown.patch
apic-shutdown.patch
reboot-on-bsp.patch
ioapic-virtwire.patch


x86 does not like tlb flush or other generic code against the init_mm
this allows those to proceed.  I think long term I want to get away from
using init_mm, to many architectures make weird assumptions.

flush-init-mm.patch

The next are the kexec patches themselves.  The generic code and then
the architecture specific code.

kexec-generic.patch
i386-kexec.patch
ppc-gc-kexec.patch

Have fun with it, and please report what breaks.

Eric
