2012-12-20sched: numa: ksm: fix oops in task_numa_placment()Hugh Dickins1-1/+4
task_numa_placement() oopsed on NULL p->mm when task_numa_fault() got called in the handling of break_ksm() for ksmd. That might be a peculiar case, which perhaps KSM could takes steps to avoid? but it's more robust if task_numa_placement() allows for such a possibility.

2012-12-20mm: do not sleep in balance_pgdat if there's no i/o congestionZlatko Calusic1-6/+6
On a 4GB RAM machine, where Normal zone is much smaller than DMA32 zone, the Normal zone gets fragmented in time. This requires relatively more pressure in balance_pgdat to get the zone above the required watermark. Unfortunately, the congestion_wait() call in there slows it down for a completely wrong reason, expecting that there's a lot of writeback/swapout, even when there's none (much more common). After a few days, when fragmentation progresses, this flawed logic translates to a very high CPU iowait times, even though there's no I/O congestion at all. If THP is enabled, the problem occurs sooner, but I was able to see it even on !THP kernels, just by giving it a bit more time to occur. The proper way to deal with this is to not wait, unless there's congestion. Thanks to Mel Gorman, we already have the function that perfectly fits the job. The patch was tested on a machine which nicely revealed the problem after only 1 day of uptime, and it's been working great.

2012-12-20UAPI: Fix up empty files in arch/cris/David Howells3-0/+5
Fix up three empty files in arch/cris/ by sticking placeholder comments in there to prevent the patch program from deleting them. I decided not to delete the arch-v*/Kbuild files as it's possibly someone might want to use them for genhdr-y lines in the future, but they could be deleted and the pointer lines removed from asm/Kbuild. The uapi/arch-v*/Kbuild files ought to be uneffected by such a change. asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in uapi/asm/swab.h. The latter, however, is exported by Kbuild.asm. This needs to be applied after the CRIS UAPI disintegration patch.

2012-12-19sparc64: Fix unrolled AES 256-bit key loops.David S. Miller1-6/+14
The basic scheme of the block mode assembler is that we start by enabling the FPU, loading the key into the floating point registers, then iterate calling the encrypt/decrypt routine for each block. For the 256-bit key cases, we run short on registers in the unrolled loops. So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that get clobbered. The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this. So if we have a mix of multi-block and single-block calls, the single-block unrolled 256-bit encrypt/decrypt can run with some of the key registers clobbered. Handle this by always explicitly loading those registers before using the non-unrolled 256-bit macro. This was discovered thanks to all of the new test cases added by Jussi Kivilinna.
