There should be no risk of being in the middle of a batch and a context switch will flush any pending batch.

2011-03-01[CPUFREQ] Missing "unregister_cpu_notifier" in powernow-k8.cNeil Brown
It appears that when powernow-k8 finds that No compatible ACPI _PSS objects found. and suggests Try again with latest BIOS. it fails the module load, but does not unregister the cpu_notifier that was registered in powernowk8_init This ends up leaving freed memory on the cpu notifier list for some other poor module (e.g. md/raid5) to come along and trip over. The following might be a partial fix, but I suspect there is probably other clean-up that is needed. ( https://bugzilla.novell.com/show_bug.cgi?id=655215 has full dmesg traces).

Mathew pointed out: | | We're supposed to be resetting trampoline_phys_low and | trampoline_phys_high here, which are two 16-bit values. | Writing 64 bits is definitely going to overwrite space | that we're not supposed to be touching. | So limit the area modified to u32.

2011-02-25omap4: prcm: Fix the CPUx clockdomain offsetsSantosh Shilimkar
CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base. The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power domain control register Fix the same. The autogen scripts is fixed thanks to Benoit Cousson With the old value, the clockdomain code would access the *_PWRSTCTRL.POWERSTATE field when it thought it was accessing the *_CLKSTCTRL.CLKTRCTRL field. In the worst case, this could cause system power management to behave incorrectly.

2011-02-24x86 quirk: Fix polarity for IRQ0 pin2 override on SB800 systemsAndreas Herrmann
On some SB800 systems polarity for IOAPIC pin2 is wrongly specified as low active by BIOS. This caused system hangs after resume from S3 when HPET was used in one-shot mode on such systems because a timer interrupt was missed (HPET signal is high active).

2011-02-22OMAP2/3: clock: fix fint calculation for DPLL_FREQSELJohn Ogness
In OMAP35X TRM Rev 2010-05 Figure 7-18 "DPLL With EMI Reduction Feature", it is shown that the internal frequency is calculated by CLK_IN/(N+1). However, the value passed to _dpll_test_fint() is already "N+1" since Linux is using the values to divide by. In the technical reference manual, "N" is referring to the divider's register value (0-127). During power management testing, it was observed that programming the wrong jitter correction value can cause the system to become unstable and eventually crash.
