2009-11-27hw-breakpoints: Use struct perf_event_attr to define user breakpointsFrederic Weisbecker
In-kernel user breakpoints are created using functions in which we pass breakpoint parameters as individual variables: address, length and type. Although it fits well for x86, this just does not scale across archictectures that may support this api later as these may have more or different needs. Pass in a perf_event_attr structure instead because it is meant to evolve as much as possible into a generic hardware breakpoint parameter structure.

2009-11-26x86/hw-breakpoints: Don't lose GE flag while disabling a breakpointFrederic Weisbecker
When we schedule out a breakpoint from the cpu, we also incidentally remove the "Global exact breakpoint" flag from the breakpoint control register. It makes us losing the fine grained precision about the origin of the instructions that may trigger breakpoint exceptions for the other breakpoints running in this cpu.

2009-11-26hw-breakpoints: Simplify error handling in breakpoint creation requestsFrederic Weisbecker
This simplifies the error handling when we create a breakpoint. We don't need to check the NULL return value corner case anymore since we have improved perf_event_create_kernel_counter() to always return an error code in the failure case.

2009-11-25x86: Rename global percpu symbol dr7 to cpu_dr7Tejun Heo
Percpu symbols now occupy the same namespace as other global symbols and as such short global symbols without subsystem prefix tend to collide with local variables. dr7 percpu variable used by x86 was hit by this. Rename it to cpu_dr7. The rename also makes it more consistent with its fellow cpu_debugreg percpu variable.

2009-11-24perf_events, x86: Fix validate_event bugStephane Eranian
The validate_event() was failing on valid event combinations. The function was assuming that if x86_schedule_event() returned 0, it meant error. But x86_schedule_event() returns the counter index and 0 is a perfectly valid value. An error is returned if the function returns a negative value. Furthermore, validate_event() was also failing for event groups because the event->pmu was not set until after hw_perf_event_init().

2009-11-11omap3: Decrease cpufreq transition latencyMike Turquette
Adjust OMAP3 frequency transition latency from 10,000,000uS to a more reasonable 300,000uS. This causes ondemand and conservative governors to sample CPU load more often resulting in more responsive behavior. Tested on Android 2.6.29; using this value and conservative governor, CORE power consumption on Zoom2 was comparable to the old and unresponsive 10,000,000uS value while UI responsiveness was greatly improved.

2009-11-11omap: Fix omapfb/lcdc on OMAP1510 broken when PM setJanusz Krzysztofik
With CONFIG_PM=y, the omapfb/lcdc device on Amstrad Delta, after initially starting correctly, breaks with the following error messages: omapfb omapfb: resetting (status 0xffffff96,reset count 1) ... omapfb omapfb: resetting (status 0xffffff96,reset count 100) omapfb omapfb: too many reset attempts, giving up. Looking closer at this I have found that it had been broken almost 2 years ago with commit 2418996e3b100114edb2ae110d5d4acb928909d2, PM fixes for OMAP1. The definite reason for broken omapfb/lcdc behavoiur in PM mode appeared to be ARM_IDLECT1:IDLIF_ARM (bit 6) put into idle regardless of LCD DMA possibly running. The bit were set based on return value of the omap_dma_running() function that did not check for dedicated LCD DMA channel status. The patch below fixes this. Note that the hardcoded register value will be fixed during the next merge cycle to use OMAP_LCDC_ defines. Currently the OMAP_LCDC_ defines are local to drivers/video/omap/lcdc.c, so let's not start moving those right now.
