powerpc: 52xx: nop out unsupported critical IRQs

Currently, when booting MPC52xx based platforms, we get:

        mpc52xx_irqhost_map: invalid irq: virq=16, l1=0, l2=3
        irq: irq-16==>hwirq-0x3 mapping failed: -22
        [WARNing skipped]

The warning is wrong since the mapping itself is valid. However, there is no
support for that type of IRQ currently. Print a proper warning and bind the irq
to a no_irq chip.

powerpc/mpc5200: move lpbfifo node and fix its interrupt property

The LPB FIFO interrupt is a peripheral interrupt, thus its L1 cell
has to be 2 instead of 3. Fix it and while at it, move the lpbfifo
node to the common dtsi file.

This patch fixes the irqdomain warning:

reiserfs: Fix lock ordering during remount

When remounting reiserfs dquot_suspend() or dquot_resume() can be called.
These functions take dqonoff_mutex which ranks above write lock so we have
to drop it before calling into quota code.

reiserfs: Protect reiserfs_quota_on() with write lock

In reiserfs_quota_on() we do quite some work - for example unpacking
tail of a quota file. Thus we have to hold write lock until a moment
we call back into the quota code.

reiserfs: Protect reiserfs_quota_write() with write lock

Calls into reiserfs journalling code and reiserfs_get_block() need to
be protected with write lock. We remove write lock around calls to high
level quota code in the next patch so these paths would suddently become
unprotected.

reiserfs: Move quota calls out of write lock

Calls into highlevel quota code cannot happen under the write lock. These
calls take dqio_mutex which ranks above write lock. So drop write lock
before calling back into quota code.

ext3: Avoid underflow of in ext3_trim_fs()

Currently if len argument in ext3_trim_fs() is smaller than one block,
the 'end' variable underflow. Avoid that by returning EINVAL if len is
smaller than file system block.

Merge remote-tracking branch 'agust/merge' into merge

Anatolij 52xx updates:

Patch for pcm030 device tree fixing the probe() in pcm030-audio-fabric
driver. Changes to this driver have been merged in 3.7-rc1 via ASoC
tree, but this required device tree patch was submitted separately to
the linux-ppc list and is still missing in mainline. Without this patch
the probe() in pcm030-audio-fabric driver wrongly returns -ENODEV.

A patch from Wolfram fixing wrong invalid critical irq warnings for
all mpc5200 boards.

Another patch for all mpc5200 device trees fixing wrong L1 cell in
the LPB FIFO interrupt property and moving the LPB FIFO node to the
common mpc5200b.dtsi file so that this common node will be present
in all mpc5200 device trees.
xen/privcmd: Correctly return success from IOCTL_PRIVCMD_MMAPBATCH

This is a regression introduced by ceb90fa0 (xen/privcmd: add
PRIVCMD_MMAPBATCH_V2 ioctl).  It broke xentrace as it used
xc_map_foreign() instead of xc_map_foreign_bulk().

Most code-paths prefer the MMAPBATCH_V2, so this wasn't very obvious
that it broke. The return value is set early on to -EINVAL, and if all
goes well, the "set top bits of the MFN's" never gets called, so the
return value is still EINVAL when the function gets to the end, causing
the caller to think it went wrong (which it didn't!)

Now also including Andres "move the ret = -EINVAL into the error handling
path, as this avoids other similar errors in future.
