2012-01-24ARM: tegra: clock: Fix Tegra3 clock lockingAlex Frid
Added locking for non-atomic access to shared registers for the following clocks: - secondary PLL dividers - audio doublers - cml (sata/pcie) clock controls Added locking for peripheral clocks secondary reference counting (register access is atomic, but some clocks may share an enable bit). Updated comments for external output clocks (shared access already protected).

2012-01-16ARM: tegra: clock: Skip clocks in Tegra3 CPU set rateAlex Frid
Reduced Tegra3 CPU clock frequency by skipping every other clock during clock rate change when either old or new rate is above 800MHz. This limits max possible frequency jump when switching between main and back-up clock sources. Added sysfs entry for minimum time to run at reduced frequency (in microseconds): /sys/module/tegra3_clocks/parameters/skipper_delay. Default delay is 10us. It should be adjusted by board initialization code based on board power distribution grid capabilities.

2012-01-12powerpc: Fix unpaired probe_hcall_entry and probe_hcall_exitLi Zhong
commit e4f387d8db3ba3c2dae4d8bdfe7bb5f4fe1bcb0d upstream. Unpaired calling of probe_hcall_entry and probe_hcall_exit might happen as following, which could cause incorrect preempt count. __trace_hcall_entry => trace_hcall_entry -> probe_hcall_entry => get_cpu_var => preempt_disable __trace_hcall_exit => trace_hcall_exit -> probe_hcall_exit => put_cpu_var => preempt_enable where: A => B and A -> B means A calls B, but => means A will call B through function name, and B will definitely be called. -> means A will call B through function pointer, so B might not be called if the function pointer is not set. So error happens when only one of probe_hcall_entry and probe_hcall_exit get called during a hcall. This patch tries to move the preempt count operations from probe_hcall_entry and probe_hcall_exit to its callers. Reported-by: Paul E.

2012-01-12powerpc/time: Handle wrapping of decrementerAnton Blanchard
commit 37fb9a0231ee43d42d069863bdfd567fca2b61af upstream. When re-enabling interrupts we have code to handle edge sensitive decrementers by resetting the decrementer to 1 whenever it is negative. If interrupts were disabled long enough that the decrementer wrapped to positive we do nothing. This means interrupts can be delayed for a long time until it finally goes negative again. While we hope interrupts are never be disabled long enough for the decrementer to go positive, we have a very good test team that can drive any kernel into the ground. The softlockup data we get back from these fails could be seconds in the future, completely missing the cause of the lockup. We already keep track of the timebase of the next event so use that to work out if we should trigger a decrementer exception.
