block: don't merge requests of different failfast settings
Block layer used to merge requests and bios with different failfast
settings. This caused regular IOs to fail prematurely when they were
merged into failfast requests for readahead.
Niel Lambrechts could trigger the problem semi-reliably on ext4 when
resuming from STR. ext4 uses readahead when reading inodes and
combined with the deterministic extra SATA PHY exception cycle during
resume on the specific configuration, non-readahead inode read would
fail causing ext4 errors. Please read the following thread for
details.
http://lkml.org/lkml/2009/5/23/21
This patch makes block layer reject merging if the failfast settings
don't match. This is correct but likely to lower IO performance by
preventing regular IOs from mingling into surrounding readahead
requests. Changes to allow such mixed merges and handle errors
correctly will be added later.

cciss: Ignore stale commands after reboot
When doing an unexpected shutdown like kexec the cciss
firmware might still have some commands in flight, which
it is trying to complete.
The driver is doing it's best on resetting the HBA,
but sadly there's a firmware issue causing the firmware
_not_ to abort or drop old commands.
So the firmware will send us commands which we haven't
accounted for, causing the driver to panic.

HP laptops with AD1984A codecs (at least mobile models) need to set
GPIO1 appropriately to indicate the mute state. The BIOS checks this
bit to judge whether the mute on or off is sent via F8 key.
Without changing this bit, the BIOS can be confused and may toggle

Fix iommu address space allocation
This fixes kernel.org bug #13584. The IOVA code attempted to optimise
the insertion of new ranges into the rbtree, with the unfortunate result
that some ranges just didn't get inserted into the tree at all. Then
those ranges would be handed out more than once, and things kind of go
downhill from there.

Fix is to correctly zero out internal ->dma value when unmapping
and make sure never to unmap unless there specifically was a mapping done.

ixgbe: fix unmap length bug
This patch addresses three WARN_ON statements from DMA-API debug code
ixgbe is mapping more than it unmaps, reduce the length of the map call and
remove the "used once" local variable.
found by Joerg Roedel <joerg.roedel@amd.com> in 2.6.30, so is a candidate

in addition, fix missing ->dma = 0 after unmap to prevent double free with
pci_unmap_single
