Merge branch 'akpm' (Andrew's patch-bomb)
Merge misc patches from Andrew Morton: "The MM tree is rather stuck while I wait to find out what the heck is happening with sched/numa.

So this is "everything else", or at least most of it - other small bits are still awaiting resolutions of various kinds." * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (180 commits) lib/decompress.c add __init to decompress_method and data kernel/resource.c: fix stack overflow in __reserve_region_with_split() omfs: convert to use beXX_add_cpu() taskstats: cgroupstats_user_cmd() may leak on error aoe: update aoe-internal version number to 50 aoe: update documentation to better reflect aoe-plus-udev usage aoe: remove unused code aoe: make dynamic block minor numbers the default aoe: update and specify AoE address guards and error messages aoe: retain static block device numbers for backwards compatibility aoe: support more AoE addresses with dynamic block device minor numbers aoe: update documentation with new URL and VM settings reference aoe: update copyright year in touched files aoe: update internal version number to 49 aoe: remove unused code and add cosmetic improvements aoe: increase net_device reference count while using it aoe: associate frames with the AoE storage target aoe: disallow unsupported AoE minor addresses aoe: do revalidation steps in order aoe: failover remote interface based on aoe_deadsecs parameter ...
