2011-03-08KEYS: Add an iovec version of KEYCTL_INSTANTIATEDavid Howells1-0/+5
Add a keyctl op (KEYCTL_INSTANTIATE_IOV) that is like KEYCTL_INSTANTIATE, but takes an iovec array and concatenates the data in-kernel into one buffer. Since the KEYCTL_INSTANTIATE copies the data anyway, this isn't too much of a problem. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>

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 Brown1-1/+8
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).

They noticed when only 4 bytes were set to 0 instead of 8, everything worked correctly. 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.

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.
