Linus Walleij 100642c7b6 ARM: 6366/1: Update U300 defconfig
This mainly removes a lot of unused subsystems (as for the mainline
drivers) in the U300 defconfig, switch of MMC debugging by default
and enables debugfs on the builds. Once we merge the drivers we'll
configure it on again.

Rabin Vincent 1d7e356594 ARM: 6418/1: ux500: rename DB8500 DMA event line macros
Change the DMA event line macros to have the name of the SoC.  Also,
have the event line number encoded in the macro since on DB5500 several
event lines are present at multiple alternate numbers.

Uwe Kleine-König fd0d67d62d ARM: 6347/2: nomadik: move nmk_gpio_probe to .devinit.text
This fixes a section mismatch reported by modpost:

	WARNING: arch/arm/plat-nomadik/built-in.o(.data+0x100): Section mismatch in reference from the variable nmk_gpio_driver to the function .init.text:nmk_gpio_probe()
	The variable nmk_gpio_driver references
	the function __init nmk_gpio_probe()
	If the reference is valid then annotate the
	variable with __init* or __refdata (see linux/init.h) or name the variable:
	*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

According to Rabin VINCENT the alternative to use platform_driver_probe
won't work because the "platform devices are not yet registered when
nmk_gpio_init() is called."

Stefan Richter a4dc090b6c firewire: ohci: work around VIA and NEC PHY packet reception bug
VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell).  Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.

(Also tested:  TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)

Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround.  Though to me it seems harmless enough
to enable for all controllers.

The log_ar_at_event() debug log will continue to show the original
status from the DMA unit.

Hugh Dickins f18194275c mm: fix hang on anon_vma->root->lock
After several hours, kbuild tests hang with anon_vma_prepare() spinning on
a newly allocated anon_vma's lock - on a box with CONFIG_TREE_PREEMPT_RCU=y
(which makes this very much more likely, but it could happen without).

The ever-subtle page_lock_anon_vma() now needs a further twist: since
anon_vma_prepare() and anon_vma_fork() are liable to change the ->root
of a reused anon_vma structure at any moment, page_lock_anon_vma()
needs to check page_mapped() again before succeeding, otherwise
page_unlock_anon_vma() might address a different root->lock.

Dan Carpenter 7a28826ac7 ALSA: pcm: add more format names
There were some new formats added in commit 15c0cee6c8 "ALSA: pcm:
Define G723 3-bit and 5-bit formats".  That commit increased
SNDRV_PCM_FORMAT_LAST as well.  My concern is that there are a couple
places which do:

        for (i = 0; i < SNDRV_PCM_FORMAT_LAST; i++) {
                if (dummy->pcm_hw.formats & (1ULL << i))
                        snd_iprintf(buffer, " %s", snd_pcm_format_name(i));
        }

I haven't tested these but it looks like if "i" were equal to
SNDRV_PCM_FORMAT_G723_24 or higher then we might read past the end of
the array.

Julia Lawall c34186ed00 net/ipv4: Eliminate kstrdup memory leak
The string clone is only used as a temporary copy of the argument val
within the while loop, and so it should be freed before leaving the
function.  The call to strsep, however, modifies clone, so a pointer to the
front of the string is kept in saved_clone, to make it possible to free it.

The sematic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
local idexpression x;
expression E;
identifier l;
statement S;
@@

*x= \(kasprintf\|kstrdup\)(...);
...
if (x == NULL) S
... when != kfree(x)
    when != E = x
if (...) {
  <... when != kfree(x)
* goto l;
  ...>
* return ...;
}
// </smpl>

Eric Paris 92b4678efa fsnotify: drop two useless bools in the fnsotify main loop
The fsnotify main loop has 2 bools which indicated if we processed the
inode or vfsmount mark in that particular pass through the loop.  These
bool can we replaced with the inode_group and vfsmount_group variables
and actually make the code a little easier to understand.

Eric Paris f72adfd540 fsnotify: fix list walk order
Marks were stored on the inode and vfsmonut mark list in order from
highest memory address to lowest memory address.  The code to walk those
lists thought they were in order from lowest to highest with
unpredictable results when trying to match up marks from each.  It was
possible that extra events would be sent to userspace when inode
marks ignoring events wouldn't get matched with the vfsmount marks.

This problem only affected fanotify when using both vfsmount and inode
marks simultaneously.
