2009-08-13Use kernel/Kconfig.preempt for ARMUwe Kleine-König
before this patch ARM had it's own definition of CONFIG_PREEMPT. Instead of that use the general definition provided in kernel/Kconfig.preempt. This patch changes the available options in *config. Namely PREEMPT isn't a stand alone bool anymore, but part of a 'choice' the following Kconfig symbols are added: PREEMPT_NONE PREEMPT_VOLUNTARY Selecting PREEMPT_NONE now produces exactly the code as not selecting PREEMPT before (apart from a comment in /sys/kernel/debug/tracing/(per_cpu/cpuX/)?trace). The only difference PREEMPT_VOLUNTARY does is that might_resched might reschedule. Both should't introduce regressions.

2009-08-14sh: unwinder: Fix up usage of unaligned accessors.Paul Mundt
This was using internal symbols for unaligned accesses, bypassing the exposed interface for variable sized safe accesses. This converts all of the __get_unaligned_cpuXX() users over to get_unaligned() directly, relying on the cast to select the proper internal routine. Additionally, the __put_unaligned_cpuXX() case is superfluous given that the destination address is aligned in all of the current cases, so just drop that outright. Furthermore, this switches to the asm/unaligned.h header instead of the asm-generic version, which was silently bypassing the SH-4A optimized unaligned ops.

2009-08-13sh: Use the new stack unwinder APIMatt Fleming
Instead of implementing our own stack unwinder via dump_trace() we should use the new stack unwinder API because it is more modular.

2009-08-13sh: Allow multiple stack unwinders to be setupMatt Fleming
Provide an interface for registering stack unwinders, where each unwinder is given a rating that describes its accuracy and complexity. The more accurate an unwinder is, the more complex it is. If a the current stack unwinder faults, then the stack unwinder with the next highest accuracy will be used in its place (provided one is available). For example, this allows unwinders, such as the DWARF unwinder, to liberally sprinkle BUG()s to catch badly formed DWARF debug info.

2009-08-12perf_counter, x86: Fix/improve apic fallbackIngo Molnar
Johannes Stezenbach reported that his Pentium-M based laptop does not have the local APIC enabled by default, and hence perfcounters do not get initialized. Add a fallback for this case: allow non-sampled counters and return with an error on sampled counters. This allows 'perf stat' to work out of box - and allows 'perf top' and 'perf record' to fall back on a hrtimer based sampling method. ( Passing 'lapic' on the boot line will allow hardware sampling to occur - but if the APIC is disabled permanently by the hardware then this fallback still allows more systems to use perfcounters. ) Also decouple perfcounter support from X86_LOCAL_APIC. -v2: fix typo breaking counters on all other systems ...

2009-08-11arch/ia64/Makefile: Remove -mtune=merced in IA64 kernel buildFenghua Yu
Between GCC version 3.4.0 and 4.3.3 (including 3.4.0 and 4.3.3), -mtune=merced is implemented in GCC. Starting from 4.4.0, -mtune=merced is deprecated. Even implemented in versions between 3.4.0 and 4.3.3, the -mtune=merced feature has been broken in some of the versions. For example, GCC 4.1.2 reports interanl tuning function errors during kernel building with -mtune=merced. Or GCC Bugzilla 16130 reports another -mtune=merced issue on GCC 3.4.1. So I would remove the -mtune=merced from IA64 kernel build. Without this option, kernel on Merced will remain the same except losing an unstable and out-of-date performance tunning feature. Since GCC version 3.4.0, -mtune=mckinley has been implemented. The -mtune=mckinley option functions the same as mtune=itanium2. And mtune=itanium2 is the default option. So we don't need to add mtune=mckinley either since its been the default option in any GCC version which implements this option. Signed-off-by: Fenghua Yu <fenghua.yu@intel.com>

Johannes Stezenbach reported that 'perf stat' does not count cache-miss and cache-references events on his Pentium-M based laptop. This is because we left them blank in p6_perfmon_event_map[], fill them in.

2009-08-11perf_counter, x86: Fix lapic printk messageIngo Molnar
Instead of this garbled bootup on UP Pentium-M systems: [ 0.015048] Performance Counters: [ 0.016004] no Local APIC, try rebooting with lapicno PMU driver, software counters only. Print: [ 0.015050] Performance Counters: [ 0.016004] no APIC, boot with the "lapic" boot parameter to force-enable it. [ 0.017003] no PMU driver, software counters only.

2009-08-11x86, mce: therm_throt - change when we print messagesDmitry Torokhov
My Latitude d630 seems to be handling thermal events in SMI by lowering the max frequency of the CPU till it cools down but still leaks the "everything is normal" events. This spams the console and with high priority printks. Adjust therm_throt driver to only print messages about the fact that temperatire returned back to normal when leaving the throttling state. Also lower the severity of "back to normal" message from KERN_CRIT to KERN_INFO. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Acked-by: H.

2009-08-10¶ARM] Orion5x: fix cpu window mapping for 88f6183Lennert Buytenhek
On the 88f6183, orion5x's setup_cpu_win() fails to ever program any mbus bridge remap registers, which causes transactions for PCI/PCIe IO/MEM space to get sent to random mbus targets. Adding a check for the 6183 in orion5x_cpu_win_can_remap() is necessary and sufficient to make PCIe wlan cards work on the 6183 reference design.
