[patch 2/2] genirq: Remove IRQF_DISABLED from core code
Remove all code which is related to IRQF_DISABLED from the core kernel code. IRQF_DISABLED still exists as a flag, but becomes a NOOP and will be removed after a grace period. That way we can easily revert to the previous behaviour by just restoring the core code. Signed-off-by: Thomas Gleixner <tglx(a)linutronix.d... 25 Mar 2010 20:53

[patch 0/2] Run interrupt handlers always with interrupts disabled
The following patch series removes the IRQF_DISABLED functionality from the core interrupt code and runs all interrupt handlers with interrupts disabled. IRQF_DISABLED is kept as a define and scheduled for feature removal. I booted and stressed that patches w/o any obvious fallout on more than 20 different sys... 25 Mar 2010 20:53

[patch] acpi: map pxms to low node ids
pxms are mapped to low node ids to maintain generic kernel use of functions such as pxm_to_node() that are used to determine device affinity. Otherwise, there is no pxm-to-node and node-to-pxm matching rule for x86_64 users of NUMA emulation where a single pxm may be bound to multiple NUMA nodes. Signed-off-by:... 25 Mar 2010 19:44

blkio_group key change: void * -> request_queue *
On Thu, Mar 25, 2010 at 11:04:23AM -0700, Chad Talbott wrote: Use request_queue to find the blkio_group of a device, rather than a cfq_data pointer. Additionally, it allows the blk-cgroup code to depend on the queue pointer itself. This avoids doing lookups for dev_t and facilitates looking up the device'... 25 Mar 2010 20:53
