[PATCH -mm 3/3] parisc: set ARCH_DMA_MINALIGN
Architectures that handle DMA-non-coherent memory need to set ARCH_DMA_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe: the buffer doesn't share a cache with the others.

[PATCH -mm 0/3] unify dma_get_cache_alignment implementations
Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma... 8 Jul 2010 03:43

[PATCH -mm] memcg: avoid css_get
This is a patch on the top of stacks of memory cgroup patches in -mm series. Tested on mmotm-2010-07-01 and works well. But requires enough tests. Even if performance improvement is not very attractive, this patch makes release_agent for memcg work fine. So, cgroup library for memcg can make use of release_agent... 8 Jul 2010 02:38

cfq-iosched: Implement cfq group idling
If group idling is enabled, wouldn't it lower the throughput on traditional drives that handle one IO at a time? Also, it would be useful to have the option of controlling idling on queue and idling on group independently. Idling on group would also be useful for achieving isolation in cases where a group uses more... 8 Jul 2010 19:13

[PATCH] asus-laptop: fix incorrect return value for write_acpi_int_ret if handle is NULL
According to the comments of write_acpi_int_ret(), write_acpi_int_ret() should return 0 if write is successful, -1 else. Thus if handle is NULL, the write does not happen, it should return -1.
