[git pull] x86 updates for v2.6.27, phase #2
From: Ingo Molnar
Date: Mon Jul 21 2008 - 11:04:44 EST
Linus,
Please pull the latest x86/for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git x86/for-linus
This contains updates from the following 21 x86 topics:
x86/urgent, x86/amd-iommu, x86/apic, x86/cleanups, x86/core,
x86/cpu, x86/fixmap, x86/gart, x86/kprobes, x86/memtest,
x86/modules, x86/nmi, x86/pat, x86/reboot, x86/setup,
x86/step, x86/unify-pci, x86/uv, x86/xen, xen-64bit,
x86/paravirt-spinlocks.
The biggest one is xen-64bit+paravirt-spinlocks - these were done in
time for the merge window and were stable and mergable, they just
depended massively on topics that are now upstream.
x86/unify-pci has been acked by Jesse. x86/modules bears special mention
as well (commit 5e5a29bf2). I'd like to also give a special mention to:
# 3f9b5cc01, x86: re-enable OPTIMIZE_INLINING
this change became possible due to UML fix 4f81c535 from Jeff Dike. It
defaults to off, it just moves out from under the scope of
CONFIG_BROKEN. (now that all known breakages have been fixed)
