xtensa: Fixup irq conversion fallout and nmi_count

2011-04-19T22:32:09Z

Some unnamed moron fatfingered the arguments of the irq chip callbacks to irq_chip instead of irq_data. While at it remove the nmi_count() print in arch_show_interrupts() which has been broken before the irq conversion already. Signed-off-by: Thomas Gleixner

percpu: Always align percpu output section to PAGE_SIZE

2011-03-24T17:50:09Z

Percpu allocator honors alignment request upto PAGE_SIZE and both the percpu addresses in the percpu address space and the translated kernel addresses should be aligned accordingly. The calculation of the former depends on the alignment of percpu output section in the kernel image. The linker script macros PERCPU_VADDR() and PERCPU() are used to define this output section and the latter takes @align parameter. Several architectures are using @align smaller than PAGE_SIZE breaking percpu memory alignment. This patch removes @align parameter from PERCPU(), renames it to PERCPU_SECTION() and makes it always align to PAGE_SIZE. While at it, add PCPU_SETUP_BUG_ON() checks such that alignment problems are reliably detected and remove percpu alignment comment recently added in workqueue.c as the condition would trigger BUG way before reaching there. For um, this patch raises the alignment of percpu area. As the area is in .init, there shouldn't be any noticeable difference. This problem was discovered by David Howells while debugging boot failure on mn10300.

xtensa: Switch do_timer() to xtime_update()

2011-01-31T13:55:46Z

xtime_update() takes the xtime_lock itself. set_linux_timer() does not need to be protected by xtime_lock.
