This patch introduces a separate struct for the block_manager.
It also uses IS_ERR to check the return value of dm_bufio_client_create
instead of testing incorrectly for NULL.
Prior to this patch a struct dm_block_manager was really an alias for
a struct dm_bufio_client. We want to add some functionality to the
block manager that will require extra fields, so this one to one
mapping is no longer valid.

A SCSI device handler might get attached to a device during the
initial device scan. We do not necessarily want to override
this when loading a multipath table, so this patch adds a new
multipath feature argument "retain_attached_hw_handler".
During SCSI device scan all loaded SCSI device handlers will be
consulted for a match (via scsi_dh's provided .match). If a match is
found that device handler will be attached. We need a way to have
userspace multipathd's provided 'hw_handler' not override the already
attached hardware handler.
When specifying the new feature 'retain_attached_hw_handler' multipath
will use the currently attached hardware handler instead of trying to
attach the one specified during table load. If no hardware handler is
attached the specified hardware handler will still be used.
Leverages scsi_dh_attach's ability to increment the scsi_dh's reference
count if the same scsi_dh name is provided when attaching - currently
attached scsi_dh name is determined with scsi_dh_attached_handler_name.
Depends upon commit 7e8a74b177

dm-thin will be most likely used with a block size that is a power of

This patch changes division and modulo operations to shifts and bit
masks if block size is a power of two.
A test that bi_sector is divisible by a block size is removed from
io_overlaps_block. Device mapper never sends bios that span a block
boundary. Consequently, if we tested that bi_size is equivalent to block
size, bi_sector must already be on a block boundary.

Non power of 2 blocksize support is needed to properly align thinp IO
on storage that has non power of 2 optimal IO sizes (e.g. RAID6 10+2).
Use sector_div to support non power of 2 blocksize for the pool's
data device. This provides comparable performance to the power of 2
math that was performed until now (as tested on modern x86_64 hardware).
The kernel currently assumes that limits->discard_granularity is a power
of two so the thin target only enables discard support if the block
size is a power of two.

remaining 4 byte holes.

dm-stripe is supposed to ensure that all the space allocated to the
stripes is fully used and that all stripes are the same size. This
patch fixes the test. It checks that device length is divisible by the
chunk size and checks that the resulting quotient is divisible by the
number of stripes (which is equivalent to testing if device length is
divisible by chunk_size * stripes).
Previously, the code only tested that the number of sectors in the target
was divisible by each of the chunk size and the number of stripes
separately, which could leave entire stripes unused.
(A setup that genuinely needs some stripes to be shorter than others
can be created by concatenating striped targets.)

Another IOMMU-API change written by me is the introduction of domain

address space can be queried.
Besides that there are a few cleanups and fixes for the NVidia Tegra

Pull HID updates from Jiri Kosina:
"The list of changes worth pointing out explicitly:
- We are getting 'UHID', which is a new framework for implementing HID
transport drivers in userspace (this is different from HIDRAW, which
is transport-independent and provides report parsing facilities;
uhid is for the other (transport) part of the pipeline).
It's needed for (and currently being used by) Bluetooth-LowEnergy,
as its specification mandates things we don't want in the kernel.
Written by David Herrmann.
- there have been quite a few bugs in runtime suspend/resume paths
(probably never reported to actually happen in the wild, but still).
Alan Stern fixed those.
- a few other driver updates and fixes and random new device support."
