A few OMAP hwmod fixes for v3.13-rc. One patch fixes some IRQ
problems with GPMC, RNG, and ISP/IVA MMUs on OMAP2/3. The other fixes
some problems with DEBUG_LL on DRA7xx.

This is a bug fix. The existing code tries to kill many
birds with one stone: Handling binding of actions to
filters, new actions and replacing of action
attributes. A simple test case to illustrate:
XXXX
moja@fe1:~$ sudo tc actions add action drop index 12
moja@fe1:~$ actions get action gact index 12
action order 1: gact action drop
random type none pass val 0
index 12 ref 1 bind 0
moja@fe1:~$ sudo tc actions replace action ok index 12
moja@fe1:~$ actions get action gact index 12
action order 1: gact action drop
random type none pass val 0
index 12 ref 2 bind 0
XXXX
The above shows the refcounf being wrongly incremented on replace.
There are more complex scenarios with binding of actions to filters
that i am leaving out that didnt work as well...

Looks like the LCD panel on LDP has been broken quite a while, and
recently got fixed by commit 0b2aa8bed3 (gpio: twl4030: Fix regression
for twl gpio output). However, there's still an issue left where the panel
backlight does not come on if the LCD drivers are built into the
kernel.
Fix the issue by registering the DPI LCD panel only after the twl4030
GPIO has probed.

The IPVS FTP helper ip_vs_ftp could trigger an OOPS in nf_ct_seqadj_set,
after commit 41d73ec053 (netfilter: nf_conntrack: make sequence number
adjustments usuable without NAT).
This is because, the seqadj ext is now allocated dynamically, and the
IPVS code didn't handle this situation. Fix this in the IPVS nfct
code by invoking the alloc function nfct_seqadj_ext_add().

There are inconsistencies wrt. feature propagation/inheritance between
macvlan and the underlying interface.
When a feature is turned off on the real device before a macvlan is
created on top, these will remain enabled on the macvlan device, whereas
turning off the feature on the lower device after macvlan creation the
kernel will propagate the changes to the macvlan.
The second issue is that, when propagating changes from underlying device
to the macvlan interface, macvlan can erronously lose its NETIF_F_LLTX flag,
as features are anded with the underlying device.
However, LLTX should be kept since it has no dependencies on physical
hardware (LLTX is set on macvlan creation regardless of the lower
device properties, see 8ffab51b3d
(macvlan: lockless tx path).
The LLTX flag is now forced regardless of user settings in absence of
layer2 hw acceleration (a6cc0cfa72,
net: Add layer 2 hardware acceleration operations for macvlan devices).
Use netdev_increment_features to rebuild the feature set on capability
changes on either the lower device or on the macvlan interface.
As pointed out by Ben Hutchings, use netdev_update_features on
NETDEV_FEAT_CHANGE event (it calls macvlan_fix_features/netdev_features_change
if needed).

Support basic dwarf(debuginfo) based operations for uprobe events. With
this change, perf probe can analyze debuginfo of user application binary
to set up new uprobe event.
This allows perf-probe --add(with local variables, line numbers) and
--line works with -x option. (Actually, --vars has already accepted -x
option)
For example, the following command shows the probe-able lines of a given
user space function. Something that so far was only available in the
'perf probe' tool for kernel space functions:
# ./perf probe -x perf --line map__load
<map__load@/home/fedora/ksrc/linux-2.6/tools/perf/util/map.c:0>
0 int map__load(struct map *map, symbol_filter_t filter)
1 {
2 const char *name = map->dso->long_name;
int nr;
5 if (dso__loaded(map->dso, map->type))
6 return 0;
8 nr = dso__load(map->dso, map, filter);
9 if (nr < 0) {
10 if (map->dso->has_build_id) {
And this shows the available variables at the given line of the
function.
# ./perf probe -x perf --vars map__load:8
Available variables at map__load:8
@<map__load+96>
char* name
struct map* map
symbol_filter_t filter
@<map__find_symbol+112>
char* name
symbol_filter_t filter
@<map__find_symbol_by_name+136>
char* name
symbol_filter_t filter
@<map_groups__find_symbol_by_name+176>
char* name
struct map* map
symbol_filter_t filter
And lastly, we can now define probe(s) with all available
variables on the given line:
# ./perf probe -x perf --add 'map__load:8 $vars'
Added new events:
probe_perf:map__load (on map__load:8 with $vars)
probe_perf:map__load_1 (on map__load:8 with $vars)
probe_perf:map__load_2 (on map__load:8 with $vars)
probe_perf:map__load_3 (on map__load:8 with $vars)
You can now use it in all perf tools, such as:
perf record -e probe_perf:map__load_3 -aR sleep 1
Changes from previous version:
- Add examples in the patch description.
- Use .text section start address and dwarf symbol address
for calculating the offset of given symbol, instead of
searching the symbol in symtab again.
With this change, we can safely handle multiple local
function instances (e.g. scnprintf in perf).

Expand given path to absolute path in the option parser, except for a
module name.
Since realpath at later stage in processing several probe point, can be
called several times (even if currently doesn't, it can happen when we
expands the feature), it is waste of the performance.
Processing it once at the early stage can avoid that.
Changes from previous one:
- Fix not to print null string.
- Allocate memory for given path/module name everytime.

* Add support for blocking IO on buffers.
* Add a data_available call back to the interface between buffer implementations

* Last user of the old event configuration interface is converted and the

* Replace all remaining instances of the IIO_ST macro with explicit filling

Miss reading of the macro arguements has led to a number of bugs so lets
just get rid of it. The final removal patch is awaiting for some fixes
to make their way into mainline.
In a couple of drivers, no elements of scan_type were even being used so
in those case, it has been dropped entirely.
* Drop a couple of of_match_ptr helper uses in drivers where devicetree is
not optional and hence the structures being protected by this always exist.
* Fix up some cases where data was read from a device in a particular
byte order, but he code placed it into a s16 or similar. These were

* Use the new ATTRIBUTE_GROUPS macro to drop some boiler plate in the triggers

* ad7746 and ad7280a - stop storing buffers on the stack, giving cleaner code

Increment 'init_count' only if the 'init' callback succeeded and decrement
'init_count' only if the 'exit' callback succeded. Increment 'power_count'
only if 'power_on' callback succeded and if it failed disable the clocks using
phy_pm_runtime_put_sync(). Also decrement 'power_count' only if 'power_off'
callback succeded and if it failed do not disable the clocks.

In case pm_runtime_get*() fails, it still
increments pm usage counter, so we *must*
make sure to pm_runtime_put() even in those
cases.
This patch fixes that mistake the same way
usbcore treats those possible failures.

Pull cgroup fixes from Tejun Heo:
"Two fixes. One fixes a bug in the error path of cgroup_create(). The
other changes cgrp->id lifetime rule so that the id doesn't get
recycled before all controller states are destroyed. This premature
id recycling made memcg malfunction"

cgroup: don't recycle cgroup id until all csses' have been destroyed
cgroup: fix cgroup_create() error handling path
Pull percpu fix from Tejun Heo:
"A single commit to fix a spurious sparse warning coming from
DEFINE_PER_CPU()'s hack to support the use of weak symbols. Shouldn't
cause observable behavior change"

Pull libata fixes from Tejun Heo:
"There's one interseting commit - "libata, freezer: avoid block device
removal while system is frozen". It's an ugly hack working around a
deadlock condition between driver core resume and block layer device
removal paths through freezer which was made more reproducible by
writeback being converted to workqueue some releases ago. The bug has
nothing to do with libata but it's just an workaround which is easy to
backport. After discussion, Rafael and I seem to agree that we don't
really need kernel freezables - both kthread and workqueue. There are
few specific workqueues which constitute PM operations and require
freezing, which will be converted to use workqueue_set_max_active()
instead. All other kernel freezer uses are planned to be removed,
followed by the removal of kthread and workqueue freezer support,
hopefully.
Others are device-specific fixes. The most notable is the addition of
NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro
M500 SSDs which otherwise suffers data corruption"
* 'for-3.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
libata, freezer: avoid block device removal while system is frozen
libata: implement ATA_HORKAGE_NO_NCQ_TRIM and apply it to Micro M500 SSDs
libata: disable a disk via libata.force params

libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8
The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

change it is possible to add DT support because driver does not need
specific board function anymore. Only static data and name of power supply
