2010-07-07ACPICA: Performance enhancement for namespace search and accessAlexey Starikovskiy
This change enhances the performance of namespace searches and walks by adding a backpointer to the parent in each namespace node. On large namespaces, this change can improve overall ACPI performance by up to 9X. Adding a pointer to each namespace node increases the overall size of the internal namespace by about 5%, since each namespace entry usually consists of both a namespace node and an ACPI operand object.

We should initialize the module dynamic debug datastructures only after determining that the module is not loaded yet. This fixes a bug that introduced in 2.6.35-rc2, where when a trying to load a module twice, we also load it's dynamic printing data twice which causes all sorts of nasty issues.

2010-07-04ARM: 6205/1: perf: ensure counter delta is treated as unsignedWill Deacon
Hardware performance counters on ARM are 32-bits wide but atomic64_t variables are used to represent counter data in the hw_perf_event structure. The armpmu_event_update function right-shifts a signed 64-bit delta variable and adds the result to the event count. This can lead to shifting in sign-bits if the MSB of the 32-bit counter value is set. This results in perf output such as: Performance counter stats for 'sleep 20': 18446744073460670464 cycles <-- 0xFFFFFFFFF12A6000 7783773 instructions # 0.000 IPC 465 context-switches 161 page-faults 1172393 branches 20.154242147 seconds time elapsed This patch ensures that the delta value is treated as unsigned so that the right shift sets the upper bits to zero.

2010-07-02i7core_edac: Avoid doing multiple probes for the same cardMauro Carvalho Chehab
As Nehalem/Nehalem-EP/Westmere devices uses several devices for the same functionality (memory controller), the default way of proping devices doesn't work. So, instead of a per-device probe, all devices should be probed at once. This means that we should block any new attempt of probe, otherwise, it will try to register the same device several times.

When calculating the DCT channel from the syndrome we need to know the syndrome type (x4 vs x8).

2010-07-01drm/i915: take struct_mutex in i915_dma_cleanup()Dan Carpenter
intel_cleanup_ring_buffer() calls drm_gem_object_unreference() (as opposed to drm_gem_object_unreference_unlocked()) so it needs to be called with "struct_mutex" held. If we don't hold the lock, it triggers a BUG_ON(!mutex_is_locked(&dev->struct_mutex)); I also audited the other places that call intel_cleanup_ring_buffer() and they all hold the lock so they're OK. This was introduced in: 8187a2b70e3 "drm/i915: introduce intel_ring_buffer structure (V2)" and it's a regression from v2.6.34.

2010-07-01drm/i915: Fix CRT hotplug regression in 2.6.35-rc1Andy Lutomirski
Commit 7a772c492fcfffae812ffca78a628e76fa57fe58 has two bugs which made the hotplug problems on my laptop worse instead of better. First, it did not, in fact, disable the CRT plug interrupt -- it disabled all the other hotplug interrupts. It seems rather doubtful that that bit of the patch fixed anything, so let's just remove it. (If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.) Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64 and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset) causes a hotplug interrupt about three seconds later. The old code never restored PORT_HOTPLUG_EN so this could only happen once, but they new code restores those registers. So just set those bits when we set up the interrupt in the first place.

2010-07-01ARM: 6195/1: OMAP3: pmu: make CPU_HAS_PMU dependent on OMAP3_EMUWill Deacon
CPU performance event counters on v7 cores will only operate if either the NIDEN or DBGEN signals are driven high. For the OMAP3 platform, these signals are driven low by default but DBGEN can be asserted by selecting the OMAP3_EMU Kconfig option, which enables the virtual clock for hardware debugging peripherals.

2010-07-01ARM: 6194/1: change definition of cpu_relax() for ARM11MPCoreWill Deacon
Linux expects that if a CPU modifies a memory location, then that modification will eventually become visible to other CPUs in the system. On an ARM11MPCore processor, loads are prioritised over stores so it is possible for a store operation to be postponed if a polling loop immediately follows it. If the variable being polled indirectly depends on the outstanding store [for example, another CPU may be polling the variable that is pending modification] then there is the potential for deadlock if interrupts are disabled. This deadlock occurs in the KGDB testsuire when executing on an SMP ARM11MPCore configuration. This patch changes the definition of cpu_relax() to smp_mb() for ARMv6 cores, forcing a flushing of the write buffer on SMP systems before the next load takes place. If the Kernel is not compiled for SMP support, this will expand to a barrier() as before.
