[PATCH 2/5] x86, mrst: add i8042_detect API for Moorestwon platform

[PATCH 4/5] Revert "Input: fixup X86_MRST selects"
From: Feng Tang <feng.tang(a)intel.com> This reverts commit 0b28bac5aef7bd1ab213723df031e61db9ff151a. After adding x86_platform's detection for i8042 controller, we don't need the force dependency on !X86_MRST any more Cc: Randy Dunlap <randy.dunlap(a)oracle.com> Signed-off-by: Feng Tang <feng.tang(a)intel.com> -... 2 Jul 2010 04:45

[PATCH v2] KVM: IOAPIC: only access APIC registers one dword at a time
The IOAPIC spec says: When accessing these registers, accesses must be done one dword at a time. For example, software should never access byte 2 from the Data register before accessing bytes 0 and 1. The hardware will not attempt to recover from a bad programming model in this case. So, this patch removes oth... 2 Jul 2010 04:45

[PATCH 2/2] scsi: build flush requests via q->prep_rq_fn
scsi-ml builds flush requests via q->prepare_flush_fn(), however, builds discard requests via q->prep_rq_fn. Using two different mechnisms for the similar requests (building commands in SCSI ULD) doesn't make sense. Handing both via q->prep_rq_fn makes the code design simpler.

[PATCH 1/2] block: introduce REQ_FLUSH flag
SCSI-ml needs a way to mark a request as flush request in q->prepare_flush_fn because it needs to identify them later (e.g. in q->request_fn or prep_rq_fn). queue_flush sets REQ_HARDBARRIER in rq->cmd_flags however the block layer also sends normal REQ_TYPE_FS requests with REQ_HARDBARRIER. So SCSI-ml can't use ... 2 Jul 2010 03:41

[PATCH 0/2] use q->prep_rq_fn for flush requests instead of q->prepare_flush_fn()

Using two different mechnisms for the similar requests (building commands in SCSI ULD) doesn't make sense. Handing both via q->prep_rq_fn makes the code simpler. We could kill q->prepare_flush_fn().
