Fix mis-merge of intel_powerclamp.c resulting in compile error

The new intel_powerclamp thermal cooling device driver was merged in
commit 2af78448fff6 (Pull thermal management updates from Zhang Rui)
without any data conflicts.  But there was a more subtle conflict I
missed: the driver uses MAX_USER_RT_PRIO, but commit 8bd75c77b7c6
("sched/rt: Move rt specific bits into new header file") had moved that
define from <linux/sched.h> to <linux/sched/rt.h>.

Which caused this build failure:

  drivers/thermal/intel_powerclamp.c: In function ‘clamp_thread’:
  drivers/thermal/intel_powerclamp.c:360:21: error: ‘MAX_USER_RT_PRIO’ undeclared (first use in this function)
  drivers/thermal/intel_powerclamp.c:360:21: note: each undeclared identifier is reported only once for each function it appears in

And because I don't do a full "make allmodconfig" build after each pull,
I didn't notice until too late.  So now the fix is here, separately from
the merge commit.

 "This series contains changes for the Marvell EBU platforms (mvebu,
  orion, kirkwood, dove) that were not part of the first set of pull
  requests because of dependencies on the MMC tree, and being submitted
  a little late.

  Notable changes are:

   - More devices get moved out of board files into device tree
     descriptions.  The remaining devices listed in there have patches
     that will get sent for 3.10, after which we can remove a lot of the
     board files entirely.  We are doing the pinctrl and mmc drivers
     here, ethernet and PCI still remain.

   - SMP support for mvebu is improved with support for the local
     interrupt controller.

   - The Guruplug board file gets replaced with a DT description.

  Unfortunately, the dependency on the MMC tree turned out to be a much
  larger problem than expected, when the MMC maintainer rebased the
  patches in his tree that all of the patches in this branch are based
  on, which caused merge conflicts between the new and old versions of
  those patches.

  To work around the merge conflicts, this branch rebases all patches on
  top of the respective MMC patches that did get merged into 3.9.  The
  patches are all identical to the versions that were part of
  linux-next, but have a new commit date."

11 years agohlist: drop the node parameter from iterators
Sasha Levin [Thu, 28 Feb 2013 01:06:00 +0000 (17:06 -0800)]
hlist: drop the node parameter from iterators

I'm not sure why, but the hlist for each entry iterators were conceived

        list_for_each_entry(pos, head, member)

The hlist ones were greedy and wanted an extra parameter:

        hlist_for_each_entry(tpos, pos, head, member)

Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.

Besides the semantic patch, there was some manual work required:

 - Fix up the actual hlist iterators in linux/list.h
 - Fix up the declaration of other iterators based on the hlist ones.
 - A very small amount of places were using the 'node' parameter, this
 was modified to use 'obj->member' instead.
 - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
 properly, so those had to be fixed up manually.

The semantic patch which is mostly the work of Peter Senna Tschudin is here:

Using prandom_bytes() is enough.  Because this data is only used
for testing, not used for cryptographic use.

nbd: fix sparse warning

I just fixed this in "drivers/block/rbd.c" and I noticed that
"drivers/block/nbd.c" has the same problem.  Fix a warning issued by
sparse by adding some lockdep annotations to indicate the queue lock gets
dropped (because it's held when do_nbd_request() is called) and
re-acquired within the function.

nbd: update documentation and link to mailinglist

Documentation/blockdev/nbd.txt contained some documentation which was
horribly outdated and probably still dates from the original patch that
added NBD support to the kernel.

This patch removes the useless and outdated bits.  The tools on nbd.sf.net
are fully documented in manpages, which is where documentation for the
non-kernel bits should live.

Additionally, add a reference to the MAINTAINERS file for the nbd-general
mailinglist that is used for discussion of the userland tools and the
kernel module already.
