We simply can't do the USB handoff at FIXUP_HEADER time, since it will
often require us to have valid IO mappings etc. But that in turn
requires a whole different approach, not this trivial one-liner.
Maybe we could teach all the USB quirk handoff handlers to only do the
quirk if the device has all its registers set up (since if it isn't
initialized, it's unlikely to be active), but regardless that will need
a whole lot more code than just saying "let's do it really early".
The proper fix is almost certainly to just leave the legacy IOMMU
mappings active until after all devices have been initialized.

USB: storage: When a device returns no sense data, call it a Hardware Error
This patch (as1294) fixes a problem that has plagued users for several
kernel releases. Some USB mass-storage devices don't return any sense
data when they encounter certain kinds of errors. The SCSI layer
interprets this to mean that the operation should be retried, and the
same thing happens -- over and over again with no limit. In some
circumstances (such as when a bus reset occurs) that is the right
thing to do, but not here.
The patch checks for this condition (a transport failure with no sense
data) and changes the result code to DID_ERROR and the sense code to
Hardware Error. This does get only a limited number of retries, and
so the command will fail relatively quickly instead of getting stuck
in an infinite loop.
The generic usbserial driver in Linux 2.6.31 halts its receiving
channel in response to throttle requests from the line discipline.
Unfortunately it drops the contents of the first URB received after
throttling takes effect. This patch corrects that problem.

Btrfs: fix uninit compiler warning in cow_file_range_nocow
The extent_type variable was exposed uninit via a goto. It should be
impossible to trigger because it is protected by a check on another
variable, but this makes sure.

Btrfs: remove negative dentry when deleting subvolumne
The use of btrfs_dentry_delete is removing dentries from the
dcache when deleting subvolumne. btrfs_dentry_delete ignores
negative dentries. This is incorrect since if we don't remove
the negative dentry, its parent dentry can't be removed.

ahci: filter FPDMA non-zero offset enable for Aspire 3810T
breaks the current git build for configurations that don't define
CONFIG_ATA_ACPI.
This adds an ifdef wrapper to ahci_gtf_filter_workaround.

This is because as we execute the loop in pmb_remap() we will
progressively try mapping the remaining address space with smaller and
smaller sizes. This isn't good because the size we use on one iteration
may be the perfect size to use on the next iteration, for instance when
the initial size is divisible by one of the PMB mapping sizes.
With this patch, we now only need two entries in the PMB to map 256MB of
address space,
entry 1: 128MB
entry 2: 128MB

sh: Plug PMB alloc memory leak
If we fail to allocate a PMB entry in pmb_remap() we must remember to
clear and free any PMB entries that we may have previously allocated,
e.g. if we were allocating a multiple entry mapping.

Btrfs: optimize fsync for the single writer case
This patch optimizes the tree logging stuff so it doesn't always wait 1 jiffie
for new people to join the logging transaction if there is only ever 1 writer.
This helps a little bit with latency where we have something like RPM where it
will fdatasync every file it writes, and so waiting the 1 jiffie for every
fdatasync really starts to add up.
