20ce902978 ALSA: hda - Fix missing ELD info when using jackpoll_ms parameter
In the case of using jackpoll_ms instead of unsol events, the jack
was correctly detected, but ELD info was not refreshed on plug-in.

And without ELD info, no proper restriction of pcm, which can in turn
break sound output on some devices.

5551a34e5a x86-64, build: Always pass in -mno-sse
Always pass in the -mno-sse argument, regardless if
-preferred-stack-boundary is supported.  We never want to generate SSE
instructions in the kernel unless we *really* know what we're doing.

According to H. J. Lu, any version of gcc new enough that we support
it at all should handle the -mno-sse option, so just add it
unconditionally.

813e8e3d6a cpuidle: Check for dev before deregistering it.
If not, we could end up in the unfortunate situation where
we dereference a NULL pointer b/c we have cpuidle disabled.

This is the case when booting under Xen (which uses the
ACPI P/C states but disables the CPU idle driver) - and can
be easily reproduced when booting with cpuidle.off=1.

b8be3a2279 Merge tag 'omap-for-v3.13/fixes-against-rc1-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:

Some omap related fixes that have come up with people moving to device
tree only based booting for omap2+.

The series contains a handful of fixes for the igep boards as they were
one of the first omap3 boards to jump over completely to device tree
based booting. So these can be considered regressions compared to
booting igep in legacy mode with board files in v3.12.

Also included are few other device tree vs legacy booting regressions:

- yet more missing omap3 .dtsi entries that have showed up booting
  various boards with device tree only

- n900 eMMC device tree fix

- fixes for beagle USB EHCI

- two fixes to make omap2420 MMC work

As we're moving omap2+ to be device tree only for v3.14, I'd like to
have v3.13 work equally well for legacy based booting and device tree
based booting. So there will be likely few more device tree related
booting patches trickling in.

This series also includes a regression fix for the omap timer posted
mode that may wrongly stay on from the bootloader for some SoCs.

2167e2399d cpufreq: fix garbage kobjects on errors during suspend/resume
This is effectively a revert of commit 5302c3fb2e ("cpufreq: Perform
light-weight init/teardown during suspend/resume"), which enabled
suspend/resume optimizations leaving the sysfs files in place.

Errors during suspend/resume are not handled properly, leaving
dead sysfs attributes in case of failures.  There are are number of
functions with special code for the "frozen" case, and all these
need to also have special error handling.

The problem is easy to demonstrate by making cpufreq_driver->init()
or cpufreq_driver->get() fail during resume.

The code is too complex for a simple fix, with split code paths
in multiple blocks within a number of functions.  It is therefore
best to revert the patch enabling this code until the error handling
is in place.

Examples of problems resulting from resume errors:

The failure to restore cpufreq devices on cancelled hibernation is
not a new bug. It is caused by the ACPI _PPC call failing unless the
hibernate is completed. This makes the acpi_cpufreq driver fail its
init.

Previously, the cpufreq device could be restored by offlining the
cpu temporarily.  And as a complete hibernation cycle would do this,
it would be automatically restored most of the time.  But after
commit 5302c3fb2e the leftover sysfs attributes will block any
device add action.  Therefore offlining and onlining CPU 1 will no
longer restore the cpufreq object, and a complete suspend/resume
cycle will replace it with garbage.

1aeef303b5 powerpc/gpio: Fix the wrong GPIO input data on MPC8572/MPC8536
For MPC8572/MPC8536, the status of GPIOs defined as output
cannot be determined by reading GPDAT register, so the code
use shadow data register instead. But the code may give the
wrong status of GPIOs defined as input under some scenarios:

1. If some pins were configured as inputs and were asserted
high before booting the kernel, the shadow data has been
initialized with those pin values.
2. Some pins have been configured as output first and have
been set to the high value, then reconfigured as input.

The above cases will make the shadow data for those input
pins to be set to high. Then reading the pin status will
always return high even if the actual pin status is low.

The code should eliminate the effects of the shadow data to
the input pins, and the status of those pins should be
read directly from GPDAT.

d59915d065 ALSA: hda - Fix headset mic input after muted internal mic (Dell/Realtek)
By trial and error, I found this patch could work around an issue
where the headset mic would stop working if you switch between the
internal mic and the headset mic, and the internal mic was muted.

It still takes a second or two before the headset mic actually starts
working, but still better than nothing.

Information update from Kailang:
  The verb was ADC digital mute(bit 6 default 1).
  Switch internal mic and headset mic will run alc_headset_mode_default.
  The coef index 0x11 will set to 0x0041.
  Because headset mode was fixed type. It doesn't need to run
  alc_determine_headset_type.
  So, the value still keep 0x0041. ADC was muted.

a7ed7c60e1 ima: properly free ima_template_entry structures
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.

7bc5f447ce (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.

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
booted with DT.
Fixes for example omap4-sdp board's keyboard backlight led.

b655028795 uio: we cannot mmap unaligned page contents
In commit 7314e613d5 ("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.
