(xen) stable/bug.fixes for 3.0-rc5

Hey Linus,

Please git pull the following branch:

git pull git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/bug.fixes

which is based on git commit acd049c6e99d2ad1195666195230f6881d1c1588 Konrad Rzeszutek Wilk (1):

xen/setup: Fix for incorrect xen_extra_mem_start.

which you had pulled in 3.0-rc4 time-frame.

This git pull fixes two rare corner cases. One is a bootup where the INT_SRC_OVR global_irq != source_irq for ACPI SCI causing the ACPI interpreter to abort and going in legacy IRQ mode. Tose machines are rare and most of them support a knob to turn it off: a BIOS option called 'ACPI SCI: Enabled/Disabled'. The other is a linker issue if a user wants an UP kernel.

Konrad Rzeszutek Wilk (2):
xen/mmu: Fix for linker errors when CONFIG_SMP is not defined. xen/pci: Use the INT_SRC_OVR IRQ (instead of GSI) to preset the ACPI SCI IRQ.
