dm thin: provide userspace access to pool metadata
This patch implements two new messages that can be sent to the thin
pool target allowing it to take a snapshot of the _metadata_. This,
read-only snapshot can be accessed by userland, concurrently with the
live target.
Only one metadata snapshot can be held at a time. The pool's status
line will give the block location for the current msnap.
Since version 0.1.5 of the userland thin provisioning tools, the
thin_dump program displays the msnap as follows:
thin_dump -m <msnap root> <metadata dev>
Available here: https://github.com/jthornber/thin-provisioning-tools
Now that userland can access the metadata we can do various things
that have traditionally been kernel side tasks:
i) Incremental backups.
By using metadata snapshots we can work out what blocks have
changed over time. Combined with data snapshots we can ensure
the data doesn't change while we back it up.

dm mpath: allow ioctls to trigger pg init
After the failure of a group of paths, any alternative paths that
need initialising do not become available until further I/O is sent to
the device. Until this has happened, ioctls return -EAGAIN.
With this patch, new paths are made available in response to an ioctl
too. The processing of the ioctl gets delayed until this has happened.
Instead of returning an error, we submit a work item to kmultipathd
(that will potentially activate the new path) and retry in ten
milliseconds.
Note that the patch doesn't retry an ioctl if the ioctl itself fails due
to a path failure. Such retries should be handled intelligently by the
code that generated the ioctl in the first place, noting that some SCSI
commands should not be retried because they are not idempotent (XOR write
commands). For commands that could be retried, there is a danger that
if the device rejected the SCSI command, the path could be errorneously
marked as failed, and the request would be retried on another path which
might fail too. It can be determined if the failure happens on the
device or on the SCSI controller, but there is no guarantee that all
SCSI drivers set these flags correctly.

typo setting the I217_MEMPWR register in e1000_suspend_workarounds_ich8lan.
Also for clarity, rename a few defines as bit definitions instead of masks.

e1000: look into the page instead of skb->data for e1000_tbi_adjust_stats()
This is another fixup where the data is not transfered into buffer
addressed by skb->data but into a page.

Merge branch 'akpm' (Fixups for Andrew's patchbomb)
Merge fixups for the mac NLS tables from Andrew.
* emailed from Andrew Morton, and one cleanup by me:
nls: fix (and rename) mac NLS table files and config options
fs/nls/Makefile: remove bogus CONFIG_ assignments

nls: fix (and rename) mac NLS table files and config options
The config options in the Kconfig file (with _CODEPAGE_ in the name)
didn't match the config option name in the Makefile (no _CODEPAGE_).
And both of them were of the hard-to-read MACXYZZY variety, which made
them hard to parse for normal humans: MACROMAN easily reads as "macro
man", not as "Mac Roman".
So rename the options to be consistent, and be NLS_MAC_xyzzy. Rename
the files to be mac-xyzzy.c too, and drop the "nls" part entirely (it's
already in the directory name).
