2009-09-28parisc: tracehook_report_syscallKyle McMartin2-13/+14
This makes parisc use the standard tracehook_report_syscall_entry and tracehook_report_syscall_exit hooks in <linux/tracehook.h>. To do this, we need to access current->thread.regs, and to know whether we're entering or exiting the syscall, so add this to syscall_trace. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>

2009-09-25[IA64] implement ticket locks for ItaniumTony Luck6-218/+92
Back in January 2008 Nick Piggin implemented "ticket" spinlocks for X86 (See commit 314cdbefd1fd0a7acf3780e9628465b77ea6a836). IA64 implementation has a couple of differences because of the available atomic operations ... e.g. we have no fetchadd2 instruction that operates on a 16-bit quantity so we make ticket locks use a 32-bit word for each of the current ticket and now-serving values. Performance on uncontended locks is about 8% worse than the previous implementation, but this seems a good trade for determinism in the contended case. Performance impact on macro-level benchmarks is in the noise. Signed-off-by: Tony Luck <tony.luck@intel.com>

This patch has the (likely harmless) side effect of moving .data.init_task inside the _edata. It also changes the alignment of .data.init_task from 16384 to THREAD_SIZE, which can in some configurations be larger than 16384.

2009-09-25omap: mailbox: Flush posted write when acking mailbox irqHiroshi DOYU1-0/+3
The only way to flush posted write to L4 bus is to do a read back of the same register right after the write. This seems to be mostly needed in interrupt handlers to avoid causing spurious interrupts. The earlier fix has been to mark the L4 bus as strongly ordered memory, which solves the problem, but causes performance penalties.
