ia64: move function declaration, ia64_cpu_local_tick() from .c to .h

2008-10-17T16:52:08Z

eliminate the function declaration ia64_cpu_local_tick() in process.c by defining in arch/ia64/include/asm/timex.h The same function will be used in a different .c file later. Signed-off-by: Isaku Yamahata Signed-off-by: Tony Luck

ACPI : Create "idle=nomwait" bootparam

2008-07-16T21:27:05Z

"idle=nomwait" disables the use of the MWAIT instruction from both C1 (C1_FFH) and deeper (C2C3_FFH) C-states. When MWAIT is unavailable, the BIOS and OS generally negotiate to use the HALT instruction for C1, and use IO accesses for deeper C-states. This option is useful for power and performance comparisons, and also to work around BIOS bugs where broken MWAIT support is advertised. http://bugzilla.kernel.org/show_bug.cgi?id=10807 http://bugzilla.kernel.org/show_bug.cgi?id=10914 Signed-off-by: Zhao Yakui Signed-off-by: Li Shaohua Signed-off-by: Len Brown Signed-off-by: Andi Kleen

ACPI: Create "idle=halt" bootparam

2008-07-16T21:27:05Z

"idle=halt" limits the idle loop to using the halt instruction. No MWAIT, no IO accesses, no C-states deeper than C1. If something is broken in the idle code, "idle=halt" is a less severe workaround than "idle=poll" which disables all power savings.

smp_call_function: get rid of the unused nonatomic/retry argument

It's never used and the comments refer to nonatomic and retry interchangably. So get rid of it. Acked-by: Jeremy Fitzhardinge Signed-off-by: Jens Axboe

[IA64] fix interrupt masking for pending works on kernel leave

2008-05-14T22:55:35Z

[Bug-fix for "[BUG?][2.6.25-mm1] sleeping during IRQ disabled"] This patch does: - enable interrupts before calling schedule() as same as others, ex. x86 - enable interrupts during ia64_do_signal() and ia64_sync_krbs() - do_notify_resume_user() is still called with interrupts disabled, since we can take short path of fsys_mode if-statement quickly. - pfm_handle_work() is also called with interrupts disabled, since it can deal interrupt mask within itself. - fix/add some comments/notes Reported-by: KOSAKI Motohiro Signed-off-by: Hidetoshi Seto Signed-off-by: Tony Luck

signals: ia64 renumber TIF_RESTORE_SIGMASK

2008-04-30T15:29:37Z

TIF_RESTORE_SIGMASK no longer needs to be in the _TIF_WORK_* masks. Those low bits are scarce. Renumber TIF_RESTORE_SIGMASK to free one up.
