2009-10-26sh: Check for return_to_handler when unwinding the stackMatt Fleming
When CONFIG_FUNCTION_GRAPH_TRACER is enabled the function graph tracer may patch return addresses on the stack with the address of return_to_handler(). This really confuses the DWARF unwinder because it will try find the caller of return_to_handler(), not the caller of the real return address. So teach the DWARF unwinder how to find the real return address whenever it encounters return_to_handler(). This patch does not cope very well when multiple return addresses on the stack have been patched. To make it work properly it would require state to track how many return_to_handler()'s have been seen so that we'd know where to look in current->curr_ret_stack[]. So for now, instead of trying to handle this, just moan if more than one return address on the stack has been patched.

2009-10-26sh: __irq_entry annotate do_IRQ().Paul Mundt
This adds an __irq_entry annotation for do_IRQ() so that the IRQ annotation in the function graph tracer works as advertized. We already have the IRQENTRY section wired up, so this is just a trivial addition to actually make use of it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-10-20crypto: aesni-intel - Fix irq_fpu_usable usageHuang Ying
When renaming kernel_fpu_using to irq_fpu_usable, the semantics of the function is changed too, from mesuring whether kernel is using FPU, that is, the FPU is NOT available, to measuring whether FPU is usable, that is, the FPU is available. But the usage of irq_fpu_usable in aesni-intel_glue.c is not changed accordingly. This patch fixes this.

2009-10-16sh: Remove BKL from landisk gio.Thomas Gleixner
The open function got the BKL via the big push down. Replace it by preempt_enable/disable as this is sufficient for an UP machine. The ioctl can be unlocked because there is no functionality which requires serialization. The usage by multiple callers is broken with and without the BKL due to the local static variable addr.

2009-10-16sh: Fix up single page flushing to use PAGE_SIZE.Valentin Sitdikov
Presently The SH-4 cache flushing code uses flush_cache_4096() for most of the real flushing work, which breaks down to a fixed 4096 unroll and increment. Not only is this sub-optimal for larger page sizes, it's also uncovered a bug in sh4_flush_dcache_page() when large page sizes are used and we have no cache aliases -- resulting in only a part of the page's D-cache lines being written back.

2009-10-14OMAP: Fix race condition with autodepsKalle Jokiniemi
There is a possible race condition in clockdomain code handling hw supported idle transitions. When multiple autodeps dependencies are being added or removed, a transition of still remaining dependent powerdomain can result in false readings of the state counter. This is especially fatal for off mode state counter, as it could result in a driver not noticing a context loss. Fixed by disabling hw supported state transitions when autodeps are being changed.

Profiling of a page fault scalability microbenchmark shows flush_hash_range is not calling the batch hpte invalidate hcall (H_BULK_REMOVE). It turns out we have a duplicate firmware feature for hcall-bulk and the current setup code stops after finding the first match. This meant we never batch and always do individual invalidates. The patch below removes the duplicate and shifts FW_FEATURE_CMO to close the gap. With the patch applied the single threaded page fault rate improves from 217169 to 238755 per second on a POWER5 test box, a 10% improvement.
