rt2x00: Disable powersaving for rt61pci and rt2800pci.

2010-01-06T23:05:23Z

commit 93b6bd26b74efe46b4579592560f9f1cb7b61994 upstream. We've had many reports of rt61pci failures with powersaving enabled. Therefore, as a stop-gap measure, disable powersaving of the rt61pci until we have found a proper solution. Also disable powersaving on rt2800pci as it most probably will show the same problem.

amd64_edac: fix forcing module load/unload

2010-01-06T23:05:16Z

commit 43f5e68733cfe8bed3c30b5c14c4993dffb29766 upstream. Clear the override flag after force-loading the module. Signed-off-by: Borislav Petkov Signed-off-by: Greg Kroah-Hartman

amd64_edac: make driver loading more robust

2010-01-06T23:05:14Z

commit 56b34b91e22313294154cee0c16e294cf8a45b61 upstream. Currently, the module does not initialize fully when the DIMMs aren't ECC but remains still loaded. Propagate the error when no instance of the driver is properly initialized and prevent further loading. Reorganize and polish error handling in amd64_edac_init() while at it.

amd64_edac: fix driver instance freeing

2010-01-06T23:05:13Z

commit 8f68ed9728193b1f2fb53ba06031b06bd8b3d1b4 upstream. Fix use-after-free errors by pushing all memory-freeing calls to the end of amd64_remove_one_instance().

x86, msr: Add support for non-contiguous cpumasks

2010-01-06T23:05:11Z

commit 505422517d3f126bb939439e9d15dece94e11d2c upstream. The current rd/wrmsr_on_cpus helpers assume that the supplied cpumasks are contiguous. However, there are machines out there like some K8 multinode Opterons which have a non-contiguous core enumeration on each node (e.g. cores 0,2 on node 0 instead of 0,1), see http://www.gossamer-threads.com/lists/linux/kernel/1160268. This patch fixes out-of-bounds writes (see URL above) by adding per-CPU msr structs which are used on the respective cores. Additionally, two helpers, msrs_{alloc,free}, are provided for use by the callers of the MSR accessors. Cc: H.

amd64_edac: unify MCGCTL ECC switching

2010-01-06T23:05:10Z

commit f6d6ae965760906d79ab29bc38507608c5971549 upstream. Unify almost identical code into one function and remove NUMA-specific usage (specifically cpumask_of_node()) in favor of generic topology methods. Remove unused defines, while at it.

cpumask: use modern cpumask style in drivers/edac/amd64_edac.c

2010-01-06T23:05:07Z

commit ba578cb34a71fb08fff14ac0796b934a8c9991e1 upstream. cpumask_t -> struct cpumask, and don't put one on the stack. (Note: this is actually on the stack unless CONFIG_CPUMASK_OFFSTACK=y). Signed-off-by: Rusty Russell Signed-off-by: Borislav Petkov Signed-off-by: Greg Kroah-Hartman

orinoco: fix GFP_KERNEL in orinoco_set_key with interrupts disabled

2010-01-06T23:04:59Z

commit 5b0691508aa99d309101a49b4b084dc16b3d7019 upstream. orinoco_set_key is called from two places both with interrupts disabled (under orinoco_lock). Use GFP_ATOMIC instead of GFP_KERNEL.
