I'm afraid I'm rather burned out w.r.t. DT bindings. As has probably
been evident, I don't have and haven't made the time to review many
recently. As such, remove myself from that MAINTAINERS entry.

The new templates management mechanism records information associated
to an event into an array of 'ima_field_data' structures and makes it
available through the 'template_data' field of the 'ima_template_entry'
structure (the element of the measurements list created by IMA).
Since 'ima_field_data' contains dynamically allocated data (which length
varies depending on the data associated to a selected template field),
it is not enough to just free the memory reserved for a
'ima_template_entry' structure if something goes wrong.
This patch creates the new function ima_free_template_entry() which
walks the array of 'ima_field_data' structures, frees the memory
referenced by the 'data' pointer and finally the space reserved for
the 'ima_template_entry' structure. Further, it replaces existing kfree()
that have a pointer to an 'ima_template_entry' structure as argument
with calls to the new function.

7bc5f447ce9d0 (ima: define new function ima_alloc_init_template() to
API) moved the initialization of 'entry' in ima_add_boot_aggregate() a
bit more below, after the if (ima_used_chip).
So, 'entry' is not initialized while being inside this if-block. So, we
should not attempt to free it.

We need to make sure that the error code from devm_of_pwm_get() is the one
the module returns in case of failure.
Restructure the code to make this possible for DT booted case.
With this patch the driver can ask for deferred probing when the board is

In commit 7314e613d5ff ("Fix a few incorrectly checked
[io_]remap_pfn_range() calls") the uio driver started more properly
checking the passed-in user mapping arguments against the size of the
actual uio driver data.
That in turn exposed that some driver authors apparently didn't realize
that mmap can only work on a page granularity, and had tried to use it
with smaller mappings, with the new size check catching that out.
So since it's not just the user mmap() arguments that can be confused,
make the uio mmap code also verify that the uio driver has the memory
allocated at page boundaries in order for mmap to work. If the device
memory isn't properly aligned, we return
[ENODEV]
The fildes argument refers to a file whose type is not supported by mmap().
as per the open group documentation on mmap.

drivers/net/ethernet/smsc/smsc911x.c is expecting supplies named
"vdd33a" and "vddvario". Currently the shared DTS file provides
"vmmc" and "vmmc_aux", and the supply lookup will fail:
smsc911x 2c000000.ethernet: Looking up vdd33a-supply from device tree
smsc911x 2c000000.ethernet: Looking up vdd33a-supply property in node /ocp/gpmc@6e000000/ethernet@gpmc failed

smsc911x 2c000000.ethernet: Looking up vddvario-supply property in node /ocp/gpmc@6e000000/ethernet@gpmc failed
Fix it!
Looks like commmit 6b2978ac40e4 (ARM: dts: Shared file for omap GPMC
connected smsc911x) made the problem more visible by moving the smc911x
configuration from the omap3-igep0020.dts file to the generic file.
But it seems we've had this problem since commit d72b4415011e
(ARM: dts: omap3-igep0020: Add SMSC911x LAN chip support).

Mux mode for wlan/sdmmc5 should be MODE0 in pinmux_wl12xx_pins and
Enable Pull up on sdmmc5_clk to detect SDIO card.
This fixes WLAN on omap4-sdp that got broken in v3.10 when we
moved omap4 to boot using device tree only as I did not have
the WL12XX card in my omap4 SDP to test with. The commit that
attempted to make WL12XX working on omap4 SDP was 775d2418f309

pin mux wl12xx_gpio and wl12xx_pins should be part of omap4_pmx_core
and not omap4_pmx_wkup. So, move wl12xx_* to omap4_pmx_core.
Fix the following error message:
pinctrl-single 4a31e040.pinmux: mux offset out of range: 0x38 (0x38)
pinctrl-single 4a31e040.pinmux: could not add functions for pinmux_wl12xx_pins 56x
SDIO card is not detected after moving pin mux to omap4_pmx_core since
sdmmc5_clk pull is disabled. Enable Pull up on sdmmc5_clk to detect SDIO card.
This fixes a regression where WLAN did not work after a warm reset
or after one up/down cycle that happened when we move omap4 to boot
using device tree only. For reference, the kernel bug is described at:

Bug report from: wenxiong@linux.vnet.ibm.com
The issue is happened in dual controller configuration. We got the
sysfs warnings when rmmod the ipr module.
enclosure_unregister() in drivers/msic/enclosure.c, call device_unregister()
for each componment deivce, device_unregister() ->device_del()->kobject_del()
->sysfs_remove_dir(). In sysfs_remove_dir(), set kobj->sd = NULL.
For each componment device,
enclosure_component_release()->enclosure_remove_links()->sysfs_remove_link()
in which checking kobj->sd again, it has been set as NULL when doing
device_unregister. So we saw all these sysfs WARNING.

The pipe code was trying (and failing) to be very careful about freeing
the pipe info only after the last access, with a pattern like:
spin_lock(&inode->i_lock);
if (!--pipe->files) {
inode->i_pipe = NULL;
kill = 1;
}
spin_unlock(&inode->i_lock);
__pipe_unlock(pipe);
if (kill)
free_pipe_info(pipe);
where the final freeing is done last.
HOWEVER. The above is actually broken, because while the freeing is
done at the end, if we have two racing processes releasing the pipe
inode info, the one that *doesn't* free it will decrement the ->files
count, and unlock the inode i_lock, but then still use the
"pipe_inode_info" afterwards when it does the "__pipe_unlock(pipe)".
This is *very* hard to trigger in practice, since the race window is
very small, and adding debug options seems to just hide it by slowing
things down.
Simon originally reported this way back in July as an Oops in
kmem_cache_allocate due to a single bit corruption (due to the final
"spin_unlock(pipe->mutex.wait_lock)" incrementing a field in a different
allocation that had re-used the free'd pipe-info), it's taken this long
to figure out.
Since the 'pipe->files' accesses aren't even protected by the pipe lock
(we very much use the inode lock for that), the simple solution is to
just drop the pipe lock early. And since there were two users of this
pattern, create a helper function for it.
Introduced commit ba5bb147330a ("pipe: take allocation and freeing of
pipe_inode_info out of ->i_mutex").

Since devm_card_release() expects parameter 'res' to be a pointer to
struct snd_soc_card, devm_snd_soc_register_card() should really pass
such a pointer rather than the one to struct device.
This bug causes the kernel Oops below with imx-sgtl500 driver when we
remove the module. It happens because with 'card' pointing to the wrong
structure, card->num_rtd becomes 0 in function soc_remove_dai_links().
Consequently, soc_remove_link_components() and in turn
soc_cleanup_codec[platform]_debugfs() will not be called on card
removal. It results in that debugfs_card_root is being removed while
its child entries debugfs_codec_root and debugfs_platform_root are still
there, and thus the kernel Oops.
Fix the bug by correcting the parameter 'res' to be the pointer to
struct snd_soc_card.

N810 audio driver has stopped working at some point. Probably when
OMAP2 was converted to common clock framework since now call to clk_enable
dumps the stack trace in drivers/clk/clk.c: __clk_enable() due
clk->prepare_count is zero.
Fix this by converting clk_enable/_disable calls to those that take care
of clock prepare/unprepare.
I'm not queueing this to linux-stable since OMAP2 common clock framework
conversion in commit ed1ebc4948fd ("ARM: OMAP2: clock: Convert to common clk")
happened before N810 was really usable in mainline and user base for N810 is
anyway small. Potential linux-stable candidates are only those after
commit 3d3a6d18abc6 ("watchdog: introduce retu_wdt driver").

Originally snd_hrtimer_callback() used iprtd->period_time for
some jiffies based estimation to determine the right moment
to call snd_pcm_period_elapsed(). As timer drifts may well be a
problem, this was changed in commit b4e82b5b785670b6 to be based
on buffer transmission progress, using iprtd->offset and
runtime->buffer_size to calculate the amount of data since last
period had elapsed.
Unfortunately, iprtd->offset counts in bytes, while
runtime->buffer_size counts frames, so adding these to find some
delta is like comparing apples and oranges, and eventually results
in negative delta values every now and then. This is no big harm,
because it simply causes snd_pcm_period_elapsed() being called
more often than necessary, as negative delta is taken for a
large unsigned value by implicit conversion rule.
Nonetheless, the calculation is broken, so one would replace
the runtime->buffer_size by its equivalent in bytes.
But then, there are chances snd_pcm_period_elapsed() is called
late, because calculating the moment for the elapsed period
into delta is based against the iprtd->last_offset, which is not
necessarily the first byte of the period in question, but some
random byte which the FIQ handler left us with in r8/r9 by
accident. Again, negative impact is low, as there are plenty of
periods already prefilled with data, and snd_pcm_period_elapsed()
will probably be called latest when the following period is
reached. However, the calculation is conceptually broken, and we
are best off removing the clever stuff altogether.
snd_pcm_period_elapsed() is now simply called once everytime
snd_hrtimer_callback() is run, which may not be most accurate,
but at least this way we are quite sure we dont miss an end of
period. There is not much extra effort wasted by superfluous
calls to snd_pcm_period_elapsed(), as the timer frequency
closely matches the period size anyway.

commit a553e4a6317b2cfc7659542c10fe43184ffe53da ("[PKTGEN]: IPSEC support")
tried to support IPsec ESP transport transformation for pktgen, but acctually
this doesn't work at all for two reasons(The orignal transformed packet has
bad IPv4 checksum value, as well as wrong auth value, reported by wireshark)
- After transpormation, IPv4 header total length needs update,
because encrypted payload's length is NOT same as that of plain text.
- After transformation, IPv4 checksum needs re-caculate because of payload
has been changed.
With this patch, armmed pktgen with below cofiguration, Wireshark is able to
decrypted ESP packet generated by pktgen without any IPv4 checksum error or
auth value error.

Eric Dumazet noticed that if we encounter an error
when processing a mergeable buffer, we don't
dequeue all of the buffers from this packet,
the result is almost sure to be loss of networking.
Jason Wang noticed that we also leak a page and that we don't decrement
the rq buf count, so we won't repost buffers (a resource leak).
Fix both issues.

A return value of 1 is interpreted as an error. See pci_driver.
in local_pci_probe(). If you're wondering how this ever could
have worked, it's because it used to be the case that only return
values less than zero were interpreted as failure. But even in
the current kernel if the driver registers its various entry
points with the kernel, and then returns a value which is
interpreted as failure, those registrations aren't undone, so
the driver still mostly works. However, the driver's remove
function wouldn't be called on rmmod, and pci power management
functions wouldn't work. In the case of Smart Array, since it
has a battery backed cache (or else no cache) even if the driver
is not shut down properly as long as there is no outstanding
i/o, nothing too bad happens, which is why it took so long to
notice.
Requesting backport to stable because the change to pci-driver.c
which requires driver probe functions to return 0 occurred between
2.6.35 and 2.6.36 (the pci power management breakage) and again
between 3.7 and 3.8 (pci_dev->driver getting set to NULL in
local_pci_probe() preventing driver remove function from being
called on rmmod.)

Currently mx53 (CortexA8) running at 1GHz reports:
Calibrating delay loop... 663.55 BogoMIPS (lpj=3317760)
Tom Evans verified that alignments of 0x0 and 0x8 run the two instructions of __loop_delay in one clock cycle (1 clock/loop), while alignments of 0x4 and 0xc take 3 clocks to run the loop twice. (1.5 clock/loop)
The original object code looks like this:
00000010 <__loop_const_udelay>:
10: e3e01000 mvn r1, #0
14: e51f201c ldr r2, [pc, #-28] ; 0 <__loop_udelay-0x8>

40: 8afffffe bhi 3c <__loop_delay>
44: e1a0f00e mov pc, lr
After adding the 'align 3' directive to __loop_delay (align to 8 bytes):
00000010 <__loop_const_udelay>:
10: e3e01000 mvn r1, #0
14: e51f201c ldr r2, [pc, #-28] ; 0 <__loop_udelay-0x8>
18: e5922000 ldr r2, [r2]

44: 8afffffe bhi 40 <__loop_delay>
48: e1a0f00e mov pc, lr
4c: e320f000 nop {0}
, which now reports:
Calibrating delay loop... 996.14 BogoMIPS (lpj=4980736)
Some more test results:
On mx31 (ARM1136) running at 532 MHz, before the patch:
Calibrating delay loop... 351.43 BogoMIPS (lpj=1757184)
On mx31 (ARM1136) running at 532 MHz after the patch:
Calibrating delay loop... 528.79 BogoMIPS (lpj=2643968)
Also tested on mx6 (CortexA9) and on mx27 (ARM926), which shows the same
BogoMIPS value before and after this patch.
