[PATCH] staging: crystalhd: printk register accesses to debug for big-endian systems
The CrystalHD device driver assumes a little endian host. In order to verify future work on endianess-independence, this patch adds printk's to track the register access to the device. This helps verify bitfield endianess correctness as well as any hard-coded assumptions in the driver code. Signed-off-by: Leon ... 23 Mar 2010 10:07

[PATCH 04/11] Allow CONFIG_MIGRATION to be set without CONFIG_NUMA or memory hot-remove
CONFIG_MIGRATION currently depends on CONFIG_NUMA or on the architecture being able to hot-remove memory. The main users of page migration such as sys_move_pages(), sys_migrate_pages() and cpuset process migration are only beneficial on NUMA so it makes sense. As memory compaction will operate within a zone and i... 23 Mar 2010 08:58

[PATCH 11/11] Do not compact within a preferred zone after a compaction failure
The fragmentation index may indicate that a failure it due to external fragmentation, a compaction run complete and an allocation failure still fail. There are two obvious reasons as to why o Page migration cannot move all pages so fragmentation remains o A suitable page may exist but watermarks are not met ... 23 Mar 2010 08:58

[PATCH 08/11] Add /proc trigger for memory compaction
This patch adds a proc file /proc/sys/vm/compact_memory. When an arbitrary value is written to the file, all zones are compacted. The expected user of such a trigger is a job scheduler that prepares the system before the target application runs.
