Pull thermal management & ACPI update from Zhang Rui,
Ho humm. Normally these things go through Len. But it's just three
small fixes, I guess I can pull directly too.
* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
exynos4_tmu_driver_ids should be exynos_tmu_driver_ids.
ACPI video: Ignore errors after _DOD evaluation.
thermal: solve compilation errors in rcar_thermal
Pull i2c embedded fixes from Wolfram Sang:
"Two patches are usual stuff.
The bigger patch is needed to correct a wrong decision made in this
merge window. We hoped to get the PIOQUEUE mode in the mxs driver
working with DMA, but it turned out to be too broken (leading to data
loss), so we now think it is best to remove it entirely and work only
with DMA now. The patch should be in 3.7. IMO, so users never get
the chance to use both modes in parallel."

it's slightly bigger than I'd probably like, but nothing looked

This I2C master can do DMA and PIOQUEUE (PIO with FIFO). Originally,
only PIOQUEUE was supported and it had issues, then DMA support was added
this cycle. The original intention was to keep PIOQUEUE since it has
less overhead what is nice for small transfers. However, runtime
switching between PIOQEUE and DMA depending on the transfer size never
worked despite a lot of trying. Since PIOQUEUE mode itself was flaky
(polling at places where interrupts failed to work) and the
implementation also imposed a size limit for transfers, it is best to
remove the support, so users don't fall over its limitations. It also
makes the driver a lot cleaner and more robust. If somebody really wants
less overhead, plain PIO mode could still be implemented with the
addidtional advantage that this mode is also available on MX23, too.

When buffer sharing with the i915 and using a 1680x1050 monitor,
the i915 gives is a 6912 buffer for the 6720 width, the code doesn't
render this properly as it uses one value to set the base address for
reading from the vmap and for where to start on the device.
This fixes it by calculating the values correctly for the device and
for the pixmap. No idea how I haven't seen this before now.

Reviewed-by: Egbert Eich <eich@suse.de>
On all dual CRTC GPUs the CRTC_CRT_ON in the RADEON_CRTC_EXT_CNTL register
controls the CRTC of the primary DAC. Therefore it is set in the DAC DMPS
function.
This is different for GPU's with a single CRTC but a primary and a
TV DAC: here it controls the single CRTC no matter where it is routed.
Therefore we set it here. This avoids an elaborate on/off state tracking
since both primary_dac_dpms() and tv_dac_dpms() functions would have
to touch this bit.
On single CRTC GPUs with just one DAC it's irrelevant where this bit
is handled.

The Radeon driver uses the analog/digital flag to determine if the
DAC or the TMDS encoder should be enabled on a DVI-I connector.
If the EDID is bogus this flag is no longer reliable. This fix
adds a fallback to DAC load detection to determine if anything
is connected to the DAC. If not and a (bogus) EDID is found it
assumes a digital display is connected.
This works around problems with some crappy IPMI devices using
Radeon ES1000.

For Radeon 7500 ATI recommends a DAC_FORCE value of 0x1ac. This value
works better on ES1000 (RV100) chips, too, as it doesn't produce any false
positives on any cards I have tested. Therefore let's assume that this
value is good for all RV100 and RV200 chipset generations.

The sleeping code in iscsi_target_tx_thread() is susceptible to the classic
missed wakeup race:
- TX thread finishes handle_immediate_queue() and handle_response_queue(),
thinks both queues are empty.
- Another thread adds a queue entry and does wake_up_process(), which does
nothing because the TX thread is still awake.
- TX thread does schedule_timeout() and sleeps forever.
In practice this can kill an iSCSI connection if for example an initiator
does single-threaded writes and the target misses the wakeup window when
queueing an R2T; in this case the connection will be stuck until the
initiator loses patience and does some task management operation (or kills
the connection entirely).
Fix this by converting to wait_event_interruptible(), which does not
suffer from this sort of race.

The expression (max_sectors * block_size) might overflow a u32
(indeed, since iblock sets max_hw_sectors to UINT_MAX, it is
guaranteed to overflow and end up with a much-too-small result in many
common cases). Fix this by doing an equivalent calculation that
doesn't require multiplication.

If the call to core_dev_release_virtual_lun0() fails, then nothing
sets ret to anything other than 0, so even though everything is
torn down and freed, target_core_init_configfs() will seem to succeed
and the module will be loaded. Fix this by passing the return value
on up the chain.

This patch fixes a regression in spc_emulate_inquiry() code where the
local scope bounce buffer was no longer getting it's memory zeroed,
causing various problems with SCSI initiators that depend upon areas
of INQUIRY EVPD=0x83 payload having been zeroed.
This bug was introduced with the following v3.7-rc1 patch + CC'ed
stable commit:
commit ffe7b0e932
Author: Paolo Bonzini <pbonzini@redhat.com>
Date: Fri Sep 7 17:30:38 2012 +0200
target: support zero allocation length in INQUIRY
Go ahead and re-add the missing memset of bounce buffer memory to be
copied into the outgoing se_cmd descriptor kmapped SGL payload.

Pull scsi target fixes from Nicholas Bellinger:
"These are the current target pending fixes headed for v3.7-rc4 code.
This includes the following highlights:
- Fix long-standing qla2xxx target bug where certain fc_port_t state
transitions could cause the internal session b-tree list to become
out-of-sync. (Roland)
- Fix task management double free of se_cmd descriptor in exception
path for users of target_submit_tmr(). (nab)
- Re-introduce simple NOP emulation of REZERO_UNIT, SEEK_6, and
SEEK_10 SCSI-2 commands in order to support legacy initiators that
still require them. (Bernhard)
Note these three patches are also CC'ed to stable.
Also, there a couple of outstanding (external) regressions that are
still being tracked down for tcm_fc(FCoE) and tcm_vhost fabrics for
v3.7.0 code, so please expect another PULL as these issues identified
-> resolved."
