ALSA: es18xx: code improvements
1. Set the third argument of the snd_device_new to not NULL, so there is
no warning about bug during chip detection. The third argument is not
used in this driver. It was changed in my previous patch.
2. Remove the fm_port and mpu_port fields from the snd_es18xx structure.
They can be converted to function arguments.
3. Remove the dmaN_size fields from the snd_es18xx structure. These
values are used only in pointer functions and can be easily calculated.
4. Remove the ctrl_lock spinlock which is used only in one read function
which is called once during chip initialization. There are many
writes to the same register and they are not protected on purpose
(see the comment ina the snd_es18xx_config_write()).
5. Use the first part of the text5Sources string table as the text4Soruces
table (they are the same).
6. Merge the same cases for the ES1887 and ES1888 when setting chip's caps.
7. Move the snd_es18xx_reset() to __devinit section.

ALSA: cs4236: detect chip in one pass
The cs4236 was two step detection with call to the snd_wss_free()
between two steps. The snd_wss_free() did not free a sound device
created in the snd_wss_create(). This caused an OOPS during module
removal as the same sound device was released twice. The same OOPS
happened if the cs4236 module loading failed.
Fix this by adapting the snd_cs4236_create() to correctly work with
chips less capable then cs4236. The snd_cs4236_create() behaves the
same as the snd_wss_create() if the chip is less capable than the cs4236.

ALSA: sh: add SuperH DAC audio driver for ALSA V4
This is a port of the sound/oss/sh_dac_audio.c driver.
The driver uses an on-chip 8-bit D/A converter, which has a speaker connected

For interrupts it uses a high-resolution timer (hrtimer).
Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx).

ALSA: snd_dma_pointer workaround for chipsets with buggy DMA
The chipsets with the isa_dma_bridge_buggy set do not stop DMA during
DMA counter reads. The DMA counter is read in two 8-bit read steps
on x86 platform. Sometimes, such reads happen during higher byte
change so the lower byte is already decremented (rolled over) but
the higher byte is not. It introduces an error that position is
moved 256 bytes ahead of the true position. Thus, the next DMA
position read can return a lower value then the previous read.
If the DMA position is decreased (reversed) the ALSA subsystem is
tricked into the playback underrun error and resets the playback.
It results in a "pop" during a playback.

value.

The "VIA DXS" controls are actually volume controls that apply to the

Commit

restoring of these volumes by "alsactl restore" that most distributions
use; the renaming in this patch cures that regression by preventing
alsactl from applying the old, wrong volume levels to the new controls.

tty: Avoid dropping ldisc_mutex over hangup tty re-initialization
A couple of people have hit the WARN_ON() in drivers/char/tty_io.c,
tty_open() that is unhappy about seeing the tty line discipline go away
during the tty hangup. See for example
http://bugzilla.kernel.org/show_bug.cgi?id=14255
and the reason is that we do the tty_ldisc_halt() outside the
ldisc_mutex in order to be able to flush the scheduled work without a
deadlock with vhangup_work.
However, it turns out that we can solve this particular case by
- using "cancel_delayed_work_sync()" in tty_ldisc_halt(), which waits
for just the particular work, rather than synchronizing with any
random outstanding pending work.
This won't deadlock, since the buf.work we synchronize with doesn't
care about the ldisc_mutex, it just flushes the tty ldisc buffers.
- realize that for this particular case, we don't need to wait for any
hangup work, because we are inside the hangup codepaths ourselves.
so as a result we can just drop the flush_scheduled_work() entirely, and
then move the tty_ldisc_halt() call to inside the mutex. That way we
never expose the partially torn down ldisc state to tty_open(), and hold
the ldisc_mutex over the whole sequence.

m32r: Fix IPI function calls for SMP
This patch fixes the m32r SMP kernel after 2.6.27.
A part of the following patch breaks m32r SMP operation.
> m32r: convert to generic helpers for IPI function calls
> commit
7b7426c8a615cf61df9a77b9df7d5b75d91e3fa0
In the above patch, a CALL_FUNC_SINGLE_IPI was newly introduced,
but the its IPI vector number was wrong in the patch code.
The m32r SMP kernel hanged-up during boot operation, because
the CPU_BOOT_IPI was called instead of CALL_FUNC_SINGLE_IPI
(CPU_BOOT_IPI had no side effect at that time because the 2nd
core had already been started up),
as a result, csd_unlock() was not called, then a dead lock
occurred in csd_lock_wait() after the detection of Compact Flash
memory as IDE generic disk.

- this info is already available after boot from

ARM: 5728/1: Proper prefetch abort handling on ARMv6 and ARMv7
Currently, on ARMv6 and ARMv7, if an application tries to execute
code (or garbage) on non-executable page it hangs. It caused by
incorrect prefetch abort handling. Now every prefetch abort
processes as a translation fault.
To fix this we have to analyze instruction fault status register
to figure out reason why we've got the abort and process it
accordingly.
To make IFSR different from DFSR we set bit 31 which is reserved in
both IFSR and DFSR.
This patch also tries to protect from future hangs on unexpected
exceptions. An application will be killed if unexpected exception
type was received.
