Subject: [GIT PULL] workqueue changes for v3.15-rc1

Hello, Linus.

PREPARE_[DELAYED_]WORK() were used to change the work function of work
items without fully reinitializing it; however, this makes workqueue
consider the work item as a different one from before and allows the
work item to start executing before the previous instance is finished
which can lead to extremely subtle issues which are painful to debug.
The interface has never been popular.  This pull request contains
patches to remove existing usages and kill the interface.  As one of
the changes was routed during the last devel cycle and another
depended on a pending change in nvme, for-3.15 contains a couple merge
commits.

In addition, interfaces which were deprecated quite a while ago -
__cancel_delayed_work() and WQ_NON_REENTRANT - are removed too.

The following changes since commit 70044d71d31d6973665ced5be04ef39ac1c09a48:

  firewire: don't use PREPARE_DELAYED_WORK (2014-03-07 10:19:57 -0500)
