They are only used during early init so lets get rid of them
after init to save some RAM.

Linus Torvalds e2aed8dfa5 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull large btrfs update from Chris Mason:
 "This pull request is very large, and the two main features in here
  have been under testing/devel for quite a while.

  We have subvolume quotas from the strato developers.  This enables
  full tracking of how many blocks are allocated to each subvolume (and
  all snapshots) and you can set limits on a per-subvolume basis.  You
  can also create quota groups and toss multiple subvolumes into a big
  group.  It's everything you need to be a web hosting company and give
  each user their own subvolume.

  The userland side of the quotas is being refreshed, they'll send out
  details on where to grab it soon.

  Next is the kernel side of btrfs send/receive from Alexander Block.
  This leverages the same infrastructure as the quota code to figure out
  relationships between blocks and their owners.  It can then compute
  the difference between two snapshots and sends the diffs in a neutral
  format into userland.

  The basic model:

        create a snapshot
        send that snapshot as the initial backup
        make changes
        create a second snapshot
        send the incremental as a backup
        delete the first snapshot
        (use the second snapshot for the next incremental)

  The receive portion is all in userland, and in the 'next' branch of my
  btrfs-progs repo.

  There's still some work to do in terms of optimizing the send side
  from kernel to userland.  The really important part is figuring out
  how two snapshots are different, and this is where we are
  concentrating right now.  The initial send of a dataset is a little
  slower than tar, but the incremental sends are dramatically faster
  than what rsync can do.

  On top of all of that, we have a nice queue of fixes, cleanups and
  optimizations."

Fix up trivial modify/del conflict in fs/btrfs/ioctl.c

Also fix up semantic conflict in fs/btrfs/send.c: the interface to
dentry_open() changed in commit 765927b2d5 ("switch dentry_open() to
struct path, make it grab references itself"), and since it now grabs
whatever references it needs, we should no longer do the mntget() on the
mnt (and we need to dput() the dentry reference we took).

pch_gbe_xmit_frame skb->len verification was incorrect in vlan case
causing bogus transfer length errors.  One correction could be:
    offset = skb->protocol == htons(ETH_P_8021Q) ? 0 : 4;
    if (unlikely(skb->len > (adapter->hw.mac.max_frame_size - offset)))
However, this verification is not necessary, so remove it.

Linus Torvalds 548ed10228 dlm for 3.6
This set includes a major redesign of recording the master node for
 resources.  The old dir hash table, which just held the master node for
 each resource, has been removed.  The rsb hash table has always duplicated
 the master node value from the dir, and is now the single record of it.
 
 Having two full hash tables of all resources has always been a waste,
 especially since one just duplicated a single value from the other.
 Local requests will now often require one instead of two lengthy hash
 table searches.
 
 The other substantial change is made possible by the dirtbl removal, and
 fixes a long standing race between resource removal and lookup by
 reworking how removal is done.  At the same time it improves the
 efficiency of removal by avoiding repeated searches through a hash bucket.
 
 The other commits include minor fixes and changes.

Shachar Shemesh aa3c8af863 tty ldisc: Close/Reopen race prevention should check the proper flag
Commit acfa747b introduced the TTY_HUPPING flag to distinguish
closed TTY from currently closing ones. The test in tty_set_ldisc
still remained pointing at the old flag. This causes pppd to
sometimes lapse into uninterruptible sleep when killed and
restarted.

Darren Hart 2588aba002 pch_uart: Add eg20t_port lock field, avoid recursive spinlocks
pch_uart_interrupt() takes priv->port.lock which leads to two recursive
spinlock calls if low_latency==1 or CONFIG_PREEMPT_RT_FULL=y (one
otherwise):

pch_uart_interrupt
  spin_lock_irqsave(priv->port.lock, flags)
  case PCH_UART_IID_RDR_TO (data ready)
  handle_rx_to
    push_rx
      tty_port_tty_get
        spin_lock_irqsave(&port->lock, flags) <--- already hold this lock
        ...
      tty_flip_buffer_push
        ...
        flush_to_ldisc
          spin_lock_irqsave(&tty->buf.lock)
            spin_lock_irqsave(&tty->buf.lock)
            disc->ops->receive_buf(tty, char_buf)
              n_tty_receive_buf
                tty->ops->flush_chars()
                uart_flush_chars
                  uart_start
                    spin_lock_irqsave(&port->lock) <--- already hold this lock

Avoid this by using a dedicated lock to protect the eg20t_port structure
and IO access to its membase. This is more consistent with the 8250
driver.  Ensure priv->lock is always take prior to priv->port.lock when
taken at the same time.

V2: Remove inadvertent whitespace change.
V3: Account for oops_in_progress for the private lock in
    pch_console_write().

Note: Like the 8250 driver, if a printk is introduced anywhere inside
      the pch_console_write() critical section, the kernel will hang
      on a recursive spinlock on the private lock. The oops case is
      handled by using a trylock in the oops_in_progress case.

Rabin Vincent a7b12929be vt: fix race in vt_waitactive()
pm_restore_console() is called from the suspend/resume path, and this
calls vt_move_to_console(), which calls vt_waitactive().

There's a race in this path which causes the process which requests the
suspend to sleep indefinitely waiting for an event which already
happened:

P1                                      P2
 vt_move_to_console()
  set_console()
    schedule_console_callback()
  vt_waitactive()
    check n == fg_console +1
                                       console_callback()
                                         switch_screen()
                                         vt_event_post() // no waiters

    vt_event_wait() // forever

Fix the race by ensuring we're registered for the event before we check
if it's already completed.

Josh Boyer 8ded2bbc18 posix_types.h: Cleanup stale __NFDBITS and related definitions
Recently, glibc made a change to suppress sign-conversion warnings in
FD_SET (glibc commit ceb9e56b3d1).  This uncovered an issue with the
kernel's definition of __NFDBITS if applications #include
<linux/types.h> after including <sys/select.h>.  A build failure would
be seen when passing the -Werror=sign-compare and -D_FORTIFY_SOURCE=2
flags to gcc.

It was suggested that the kernel should either match the glibc
definition of __NFDBITS or remove that entirely.  The current in-kernel
uses of __NFDBITS can be replaced with BITS_PER_LONG, and there are no
uses of the related __FDELT and __FDMASK defines.  Given that, we'll
continue the cleanup that was started with commit 8b3d1cda4f
("posix_types: Remove fd_set macros") and drop the remaining unused
macros.

Additionally, linux/time.h has similar macros defined that expand to
nothing so we'll remove those at the same time.

Hauke Mehrtens 1f03bf06e4 bcma: fix invalid PMU chip control masks
Commit b9562545ef ("bcma: complete workaround for BCMA43224 and
BCM4313") introduced the wrong masks for setting the chip control
registers - the "mask" parameter is inverse.

It should be the mask of bits *not* changed, which is admittedly a bit
non-intuitive.

The incorrect mask not only causes the driver to not work correctly on
the chips affected (eg the BCM43224 on the Macbook Air 4,2) but the
state persists over a soft reset, causing the next boot to not
necessarily see the device correctly.

    bcma: add new cores at the end of list

This should be fixed properly later so that the correct interrupt
numbers are assigned to the cores independently from the ordering of
the list. This patch restores the old behavior again. I will look into
the problem more deeply later.

I also changed the order of the list with the cores and their assigned
interrupt number which gets printed to the log. Now they are printed in
the same order like all the other lists of cores and like it was done
before the patch which changed the order.

Here's the big driver core pull request for 3.6-rc1.
 
 Unlike 3.5, this kernel should be a lot tamer, with the printk changes now

Linus Torvalds b13bc8dda8 Staging tree patches for 3.6-rc1
Here's the big staging tree merge for the 3.6-rc1 merge window.
 
 There are some patches in here outside of drivers/staging/, notibly the iio
 code (which is still stradeling the staging / not staging boundry), the pstore
 code, and the tracing code.  All of these have gotten ackes from the various
 subsystem maintainers to be included in this tree.  The pstore and tracing
 patches are related, and are coming here as they replace one of the android
 staging drivers.
 
 Otherwise, the normal staging mess.  Lots of cleanups and a few new drivers
 (some iio drivers, and the large csr wireless driver abomination.)
 
 Note, you will get a merge issue with the following files:
 	drivers/staging/comedi/drivers/s626.h
 	drivers/staging/gdm72xx/netlink_k.c
 both of which should be trivial for you to handle.

TI LP8788 PMU has the current sink as the keyboard led driver.
The brightness is controlled by the i2c commands.
Configurable parameters can be defined in the platform side.

Patch v2.
(a) use workqueue on changing the brightness

(b) use mutex_lock/unlock when the brightness is set
    and the led block of lp8788 device is enabled

(c) remove err_dev on _probe()
    : just return as returned value if any errors

(d) replace module_init/exit() with module_platform_driver()

(e) add led configuration structure and loading them by default
    if platform data is null

Daniel writes: (this pull is the one with the bad patch dropped)
First pile of fixes for 3.6 already, and I'm afraid it's a bit larger than
what I'd wish for. But I've moved all the feature-y stuff to -next, so
this really is all -fixes. Most of it is handling fallout from the hw
context stuff, discovered now that mesa git has started using them for
real. Otherwise all just small fixes:
- unbreak modeset=0 on gen6+ (regressed in next)
- const mismatch fix for ->mode_fixup
- simplify overly clever lvds modeset code (current code can totally
  confuse backlights, resulting in broken panels until a full power draw
  restores them).
- fix some fallout from the flushing_list disabling (regression only
  introduced in -next)
- DP link train improvements (this also kills the last 3.2 dp regression
  afaik)
- bugfix for the new ddc VGA detection on newer platforms
- minor backlight fixes (one of them a -next regression)
- only enable the required PM interrupts (to avoid waking up the cpu
  unnecessarily)
- some really minor bits (workaround clarification, make coverty happy,
  hsw init fix)
