The following changes since commit 7f00a2495bf5b98b097c47be5d6e2d4114ec39bf:
Ingo Molnar (1):
Merge branches 'x86/cleanups', 'x86/mm', 'x86/setup' and 'linus' into x86/core

are available in the git repository at:

git://git.kernel.org/pub/scm/linux/kernel/git/jaswinder/linux-2.6-tiptop.git x86/core

Jaswinder Singh Rajput (5):
x86: cpu/cpu.h cleanup
x86: irq.c use same path for show_interrupts
x86: irq.c keep CONFIG_X86_LOCAL_APIC interrupts together
x86: apic/io_apic.c define msi_ir_chip and ir_ioapic_chip all the time
x86: e820.h fix various signedness issues in setup.c and e820.c
