a5062dee82 ALSA: hda - add explicit include of err.h
Since every caller of snd_hda_jack_detect_enable_callback needs to
use the macros from err.h, it makes sense to include it directly
from hda_jack.h.

8bb1ffdf76 ALSA: hda - Replace strnicmp with strncasecmp
The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics
and a slightly buggy strncasecmp. The latter is the POSIX name, so
strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper
for the new strncasecmp to avoid breaking existing users.

To allow the compat wrapper strnicmp to be removed at some point in
the future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.

f8fb117034 ALSA: hda - Use standard hda_jack infrastructure for CA0132 driver
For its headphone, mic and DSP responses, we can use the standard
hda_jack infrastructure in CA0132 driver, too.  The only point to
handle carefully is the delayed headphone jack handling.  It tries to
react after a certain delay.  Here we use the existing block_report
flag in hda_jack_tbl (that was implemented for HDMI).

aa699c492e ALSA: hda - Remove superfluous callbacks from STAC/IDT codecs
Now we can register multiple callbacks to each jack, most of hooks
used in STAC/IDT codecs can be removed by enabling the powermap update
callback for all relevant pins.  Along with this, the call of
stac_init_power_map() can be moved back to stac_parse_auto_config()
and the own build_controls callback can be removed, too.

1a4f69d5aa ALSA: hda - Allow multiple callbacks for jack
So far, hda_jack infrastructure allows only one callback per jack, and
this makes things slightly complicated when a driver wants to assign
multiple tasks to a jack, e.g. the standard auto-mute with a power
up/down sequence.  This can be simplified if the hda_jack accepts
multiple callbacks.

This patch is such an extension: the callback-specific part (the
function and private_data) is split to another struct from
hda_jack_tbl, and multiple such objects can be assigned to a single
hda_jack_tbl entry.

The new struct hda_jack_callback is passed to each callback function
now, thus the patch became bigger than expected.  But these changes
are mostly trivial.

62f949bf6b ALSA: hda - Get rid of action field from struct hda_jack_tbl
The action value assigned to each hda_jack_tbl entry is mostly
superfluous.  The actually used values are either the widget NID or a
value specific to the callback.

The former case can be simply replaced by a reference to widget NID
itself.  The only place doing the latter is STAC/IDT codec driver for
the powermap handling.  But, the code doesn't need to check the action
field at all -- the function jack_update_power() is called either with
a specific pin or with NULL.  So the check of jack->action can be
removed completely there, too.

7a9744cb45 ALSA: hda - Fix invalid pin powermap without jack detection
When a driver is set up without the jack detection explicitly (either
by passing a model option or via a specific fixup), the pin powermap
of IDT/STAC codecs is set up wrongly, resulting in the silence
output.  It's because of a logic failure in stac_init_power_map().
It tries to avoid creating a callback for the pins that have other
auto-hp and auto-mic callbacks, but the check is done in a wrong way
at a wrong time.  The stac_init_power_map() should be called after
creating other jack detection ctls, and the jack callback should be
created only for jack-detectable widgets.

This patch fixes the check in stac_init_power_map() and its callee
at the right place, after snd_hda_gen_build_controls().

d89c6c0c91 ALSA: hda - Add TLV_DB_SCALE_MUTE bit for relevant controls
The DACs on Sigmatel/IDT codecs do mute at the lowest volume level,
and in the earlier drivers, we passed TLV_DB_SCALE_MUTE bit for each
volume control element like Speaker and Headphone as well as Master.
Along with the translation to the generic parser, however, the TLV bit
was lost for the slave controls (e.g. Speaker) but set only to
Master.  In theory this should have sufficed, but apps, particularly
PA, do care the slave volume bits, so we seem to see a regression in
the volume controls.

This patch adds a flag to hda_gen_spec to specify the DAC mute
feature, and adds the TLV bit properly for all relevant volume
controls.  Also, the TLV bit for vmaster is set in hda_generic.c, so
that we can get rid of all tricks from the codec driver side.

As the similar hack is applied to Conexant 5051 stuff, we can get rid
of it as well.

257f8cce5d ALSA: pcm: Allow nonatomic trigger operations
Currently, many PCM operations are performed in a critical section
protected by spinlock, typically the trigger and pointer callbacks are
assumed to be atomic.  This is basically because some trigger action
(e.g. PCM stop after drain or xrun) is done in the interrupt handler.
If a driver runs in a threaded irq, however, this doesn't have to be
atomic.  And many devices want to handle trigger in a non-atomic
context due to lengthy communications.

This patch tries all PCM calls operational in non-atomic context.
What it does is very simple: replaces the substream spinlock with the
corresponding substream mutex when pcm->nonatomic flag is set.  The
driver that wants to use the non-atomic PCM ops just needs to set the
flag and keep the rest as is.  (Of course, it must not handle any PCM
ops in irq context.)

Note that the code doesn't check whether it's atomic-safe or not, but
trust in 100% that the driver sets pcm->nonatomic correctly.

One possible problem is the case where linked PCM substreams have
inconsistent nonatomic states.  For avoiding this, snd_pcm_link()
returns an error if one tries to link an inconsistent PCM substream.

 - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select' statements;
 - wire up renameat2 syscall.
 
 Various fixes:
 - fix address checks in dma_{alloc,free}_coherent (runtime BUG);
 - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage);
 - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss (runtime
   unrecoverable exception);
 - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace register
   clobbering);
 - fix kernel/user jump out of fast_unaligned (potential runtime unrecoverabl
   exception);
 - replace termios IOCTL code definitions with constants (userspace build
   breakage).

Pull Xtensa updates from Chris Zankel:
 "Xtensa improvements for 3.17:
   - support highmem on cores with aliasing data cache.  Enable highmem
     on kc705 by default
   - simplify addition of new core variants (no need to modify Kconfig /
     Makefiles)
   - improve robustness of unaligned access handler and its interaction
     with window overflow/underflow exception handlers
   - deprecate atomic and spill registers syscalls
   - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select'
     statements
   - wire up renameat2 syscall.

  Various fixes:
   - fix address checks in dma_{alloc,free}_coherent (runtime BUG)
   - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage)
   - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss
     (runtime unrecoverable exception)
   - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace
     register clobbering)
