Hey Linus,
Please git pull the following tag:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git
stable/for-linus-3.9-rc0-tag
which has two new ACPI drivers for Xen - a physical CPU offline/online and
a memory hotplug. The way this works is that ACPI kicks the drivers and they
make the appropiate hypercall to the hypervisor to tell it that there is a new
CPU or memory. There also some changes to the Xen ARM ABIs and couple of fixes.
One particularly nasty bug in the Xen PV spinlock code was fixed by Stefan Bader
- and has been there since the 2.6.32!
During the linux-next cycle we found that some of the changes in
Rafael''s
pm+acpi-3.9-rc1 tree will cause compile conflicts with my tree.
Stephen Rothwell found and developed a fix - which I am including as an
attachment to this - please apply it immediately after my tree. There are some
other patches that ought to be done on top of this to deal with the new ACPI API
changes - I''ve them in this #linux-next-resolved tree:
http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git;a=shortlog;h=refs/heads/linux-next-resolved
if you are curious - but I was thinking to submit them _after_ the rc1 has been
tagged as I am sure I will have some bug-fixes. There looks to be a lot
of regressions this season already :-(
