When a Xen Dom0 kernel boots on a hypervisor, it gets access to the raw-hardware ACPI tables. While it parses the idle tables for the hypervisor's beneift, it uses HLT for its own idle. Rather than have xen scribble on pm_idle and access default_idle, have it simply disable_cpuidle() so acpi_idle will not load and architecture default HLT will be used. cc: xen-devel@lists.xensource.com Tested-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Acked-by: H.

2011-08-03ACPI, APEI, GHES, Error records content based throttleHuang Ying
printk is used by GHES to report hardware errors. Ratelimit is enforced on the printk to avoid too many hardware error reports in kernel log. Because there may be thousands or even millions of corrected hardware errors during system running. Currently, a simple scheme is used. That is, the total number of hardware error reporting is ratelimited. This may cause some issues in practice. For example, there are two kinds of hardware errors occurred in system. One is corrected memory error, because the fault memory address is accessed frequently, there may be hundreds error report per-second. The other is corrected PCIe AER error, it will be reported once per-second. Because they share one ratelimit control structure, it is highly possible that only memory error is reported. To avoid the above issue, an error record content based throttle algorithm is implemented in the patch. Where after the first successful reporting, all error records that are same are throttled for some time, to let other kinds of error records have the opportunity to be reported. In above example, the memory errors will be throttled for some time, after being printked. Then the PCIe AER error will be printked successfully.

2011-08-03ACPI, APEI, GHES, printk support for recoverable error via NMIHuang Ying
Some APEI GHES recoverable errors are reported via NMI, but printk is not safe in NMI context. To solve the issue, a lock-less memory allocator is used to allocate memory in NMI handler, save the error record into the allocated memory, put the error record into a lock-less list. On the other hand, an irq_work is used to delay the operation from NMI context to IRQ context. The irq_work IRQ handler will remove nodes from lock-less list, printk the error record and do some further processing include recovery operation, then free the memory.

2011-08-03tcm_fc: Handle DDP/SW fc_frame_payload_get failures in ft_recv_write_dataKiran Patil
Problem: HW DDP context was not invalidated in case of ABORTS, etc... This leads to the problem where memory pages which are used for DDP as user descriptor could get reused for some other purpose (such as to satisfy new memory allocation request either by kernel or user mode threads) and since HW DDP context was not invalidated, HW continue to write to those pages, hence causing memory corruption. Fix: Either on incoming ABORTS or due to exchange time out, allowed the target to cleanup HW DDP context if it was setup for respective ft_cmd. Added new function to perform this cleanup, furthur it can be enhanced for other cleanup activity. Fix ft_recv_write_data() to properly handle fc_frame_payload_get to return pointer to payload if it exist. If there is no payload which is most common case (+ve case in case if DDP is working as expected, it will return NULL. Yes, scope of buf is limited to printk. Invalidation of HW context (which is done inside ft_invl_hw_context() is necessary in SUCCESS and FAILURE case of DDP. Hence invalidation is DONE as long as there was DDP setup (whether it worked correctly or not, NOTE: For some reason, if there is any error w.r.t DDP such as out of order packet reception, HW simply post the full packet in rx queue.

2011-08-02thermal: make THERMAL_HWMON implementation fully internalJean Delvare
THERMAL_HWMON is implemented inside the thermal_sys driver and has no effect on drivers implementing thermal zones, so they shouldn't see anything related to it in <linux/thermal.h>. Making the THERMAL_HWMON implementation fully internal has two advantages beyond the cleaner design: * This avoids rebuilding all thermal drivers if the THERMAL_HWMON implementation changes, or if CONFIG_THERMAL_HWMON gets enabled or disabled. * This avoids breaking the thermal kABI in these cases too, which should make distributions happy. The only drawback I can see is slightly higher memory fragmentation, as the number of kzalloc() calls will increase by one per thermal zone. But I doubt it will be a problem in practice, as I've never seen a system with more than two thermal zones.

2011-08-02thermal: hide CONFIG_THERMAL_HWMONJean Delvare
It's about time to revert 16d752397301b9 ("thermal: Create CONFIG_THERMAL_HWMON=n"). Anybody running a kernel >= 2.6.40 would also be running a recent enough version of lm-sensors. Actually having CONFIG_THERMAL_HWMON is pretty convenient so instead of dropping it, we keep it but hide it.

The helper functions for reading u32 integers, u32 arrays and strings should have the property name as a const pointer. Cc: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Jamie Iles <jamie@jamieiles.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-08-02spi/pl022: remove function cannot exitLinus Walleij
The remove function in the PL022 driver cannot abort the remove function any way, so restructure the code so as not to make that assumption. Remove will now proceed no matter whether it can stop the transfer queue or not.
