This is similar to the set_peek_off patch where calling bind while the
socket is stuck in unix_dgram_recvmsg() will block and cause a hung task
spew after a while.
This is also the last place that did a straightforward mutex_lock(), so
there shouldn't be any more of these patches.

This is because we hold the rtnl_lock() before ndo_change_mtu() and try to flush
the work in netvsc_change_mtu(), in the mean time, netdev_notify_peers() may be
called from worker and also trying to hold the rtnl_lock. This will lead the
flush won't succeed forever. Solve this by not canceling and flushing the work,
this is safe because the transmission done by NETDEV_NOTIFY_PEERS was
synchronized with the netif_tx_disable() called by netvsc_change_mtu().

If a user calls 'cpupower set --perf-bias 15', the process will end with
a SIGSEGV in libc because cpupower-set passes a NULL optarg to the atoi
call. This is because the getopt_long structure currently has all of
the options as having an optional_argument when they really have a
required argument. We change the structure to use required_argument to
match the short options and it resolves the issue.

The HCI User Channel is an admin operation which enforces CAP_NET_ADMIN
when binding the socket. Problem now is that it then requires also
CAP_NET_RAW when calling into hci_sock_sendmsg. This is not intended
and just an oversight since general HCI sockets (which do not require
special permission to bind) and HCI User Channel share the same code
path here.
Remove the extra CAP_NET_RAW check for HCI User Channel write operation
since the permission check has already been enforced when binding the
socket. This also makes it possible to open HCI User Channel from a
privileged process and then hand the file descriptor to an unprivilged
process.

This patch changes the igb_phy_has_link function to check the value of the
parameter before deciding to use udelay or mdelay in order to be sure that
the value is not too high for udelay function.

Pull ARM fixes from Russell King:
"This resolves some further issues with the dma mask changes on ARM
which have been found by TI and others, and also some corner cases
with the updates to the virtual to physical address translations.
Konstantin also found some problems with the unwinder, which now
performs tighter verification that the stack is valid while unwinding"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: fix asm/memory.h build error
ARM: 7917/1: cacheflush: correctly limit range of memory region being flushed
ARM: 7913/1: fix framepointer check in unwind_frame
ARM: 7912/1: check stack pointer in get_wchan

A fix for possible memory corruption during DM table load, fix a
possible leak of snapshot space in case of a crash, fix a possible
deadlock due to a shared workqueue in the delay target, fix to
initialize read-only module parameters that are used to export metrics
for dm stats and dm bufio.
Quite a few stable fixes were identified for both the thin-provisioning
and caching targets as a result of increased regression testing using
the device-mapper-test-suite (dmts). The most notable of these are the
reference counting fixes for the space map btree that is used by the
dm-array interface -- without these the dm-cache metadata will leak,
resulting in dm-cache devices running out of metadata blocks. Also,
some important fixes related to the thin-provisioning target's
transition to read-only mode on error.

A small set of driver fixes plus one larger core change which changes
the way we check to see if we're using DT so that there aren't any races
between deciding we're using DT and the regulator subsystem noticing.
This makes the new support for substituting a dummy regulator and
optional regulators work a lot better on DT systems since it ensures
that we don't trigger probe deferral when we shouldn't which was causing
bugs in clients.

An old array block could have its reference count decremented below
zero when it is being replaced in the btree by a new array block.
The fix is to increment the old ablock's reference count just before
inserting a new ablock into the btree.
