Oops, apparently no-one I cc'd at intel actually bothered to check this
patch for the isci driver:
commit e73823f7a2c921dcf068d34ea03bd682498d9e42
Author: James Bottomley <JBottomley@Parallels.com>
Date: Tue May 7 15:38:18 2013 -0700
[SCSI] libsas: implement > 16 byte CDB support
sci_swab32_cpy needs multiples of four, so for commands that aren't that, it's
rounding the wrong way. fix by doing (len+3)/4 instead of len/4.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc fixes from Ben Herrenschmidt:
"Here is a series of powerpc fixes. It's a bit big, mostly because of
the series of 11 "EEH" patches from Gavin. The EEH (Our IBM specific
PCI/PCIe Enhanced Error Handling) code had been rotting for a while
and this merge window saw a significant rework & fixing of it by Gavin
Shan.
However, that wasn't complete and left some open issues. There were
still a few corner cases that didn't work properly, for example in
relation to hotplug and devices without explicit error handlers. We
had some patches but they weren't quite good enough yet so I left them
off the 3.11 merge window.
Gavin since then fixed it all up, we ran quite a few rounds of testing
and it seems fairly solid (at least probably more than it has ever
been). This should probably have made -rc1 but both Gavin and I took
some vacation so it had to wait for -rc2.
The rest is more bug fixes, mostly to new features recently added, for
example, we missed the cpu table entry for one of the two models of P8
(we didn't realize they had different PVR [Processor Version Register]
values), some module CRC issues, etc..."

The usage of strict_strtol() is not preferred, because
strict_strtol() is obsolete. Thus, kstrtos32() should be

imx6q contains one Synopsys AHCI SATA controller, But it can't share
ahci_platform driver with other controllers because there are some
misalignments of the generic AHCI controller - the bits definitions of
the HBA registers, the Vendor Specific registers, the AHCI PHY clock
and the AHCI signals adjustment window(GPR13 register).
- CAP_SSS(bit20) of the HOST_CAP is writable, default value is '0',
should be configured to be '1'
- bit0 (only one AHCI SATA port on imx6q) of the HOST_PORTS_IMPL
should be set to be '1'.(default 0)
- One Vendor Specific register HOST_TIMER1MS(offset:0xe0) should be
configured regarding to the frequency of AHB bus clock.
- Configurations of the AHCI PHY clock, and the signal parameters of
the GPR13
Setup its own ahci sata driver, contained the imx6q specific
initialized codes, re-use the generic ahci_platform driver, and keep
the generic ahci_platform driver clean as much as possible.

The recent addition of lockdep support to reservations and their subsequent
use by TTM showed up a number of potential problems with the way qxl was using
TTM objects.
a) it was allocating objects, and reserving them later without validating
underneath the reservation, which meant in extreme conditions the objects could
be evicted before the reservation ever used them.
b) it was reserving objects straight after allocating them, but with no
ability to back off should the reservations fail. It now allocates the necessary
objects then does a complete reservation pass on them to avoid deadlocks.
c) it had two lists per release tracking objects, unnecessary complicating
the reservation process.
This patch removes the dual object tracking, adds reservations ticket support
to the release and fence object handling. It then ports the internal fb
drawing code and the userspace facing ioctl to use the new interfaces properly,
along with cleanup up the error path handling in some codepaths.

In order to fix an issue with reservations we need to create the releases
as pre-pinned objects, this changes the placement interface and bo creation
interface to allow creating pinned objects to save nested reservations later.
This is just a stepping stone to main fix which follows to actually fix how
qxl deals with reservations.

Due to the nature of qxl hw we cannot queue operations while in an irq
context, so we queue these operations as best we can until atomic allocations
fail, and dequeue them later in a work queue.
Daniel looked over the locking on the list and agrees it should be sufficent.
The atomic allocs use no warn, as the last thing we want if we haven't memory
to allocate space for a printk in an irq context is more printks.

EDAC MC0: Giving out device to 'sbridge_edac.c' 'Sandy Bridge Socket#0': DEV 0000:3f:0e.0
EDAC sbridge: Driver loaded.
What happens is that bus_register needs a statically allocated lock_key
because the last is handed in to lockdep. However, struct mem_ctl_info
embeds struct bus_type (the whole struct, not a pointer to it) and the
whole thing gets dynamically allocated.
Fix this by using a statically allocated struct bus_type for the MC bus.

`do_cmd_ioctl()` is called with the comedi device's mutex locked to
process the `COMEDI_CMD` ioctl to set up comedi's asynchronous command
handling on a comedi subdevice. `comedi_read()` and `comedi_write()`
are the `read` and `write` handlers for the comedi device, but do not
lock the mutex (for performance reasons, as some things can hold the
mutex for quite a long time).
There is a race condition if `comedi_read()` or `comedi_write()` is
running at the same time and for the same file object and comedi
subdevice as `do_cmd_ioctl()`. `do_cmd_ioctl()` sets the subdevice's
`busy` pointer to the file object way before it sets the `SRF_RUNNING` flag
in the subdevice's `runflags` member. `comedi_read() and
`comedi_write()` check the subdevice's `busy` pointer is pointing to the
current file object, then if the `SRF_RUNNING` flag is not set, will call
`do_become_nonbusy()` to shut down the asyncronous command. Bad things
can happen if the asynchronous command is being shutdown and set up at
the same time.
To prevent the race, don't set the `busy` pointer until
after the `SRF_RUNNING` flag has been set. Also, make sure the mutex is
held in `comedi_read()` and `comedi_write()` while calling
`do_become_nonbusy()` in order to avoid moving the race condition to a
point within that function.
Change some error handling `goto cleanup` statements in `do_cmd_ioctl()`
to simple `return -ERRFOO` statements as a result of changing when the
`busy` pointer is set.

Comedi devices can do blocking read() or write() (or poll()) if an
asynchronous command has been set up, blocking for data (for read()) or
buffer space (for write()). Various events associated with the
asynchronous command will wake up the blocked reader or writer (or
poller). It is also possible to force the asynchronous command to
terminate by issuing a `COMEDI_CANCEL` ioctl. That shuts down the
asynchronous command, but does not currently wake up the blocked reader
or writer (or poller). If the blocked task could be woken up, it would
see that the command is no longer active and return. The caller of the
`COMEDI_CANCEL` ioctl could attempt to wake up the blocked task by
sending a signal, but that's a nasty workaround.
Change `do_cancel_ioctl()` to wake up the wait queue after it returns
from `do_cancel()`. `do_cancel()` can propagate an error return value
from the low-level comedi driver's cancel routine, but it always shuts
the command down regardless, so `do_cancel_ioctl()` can wake up he wait
queue regardless of the return value from `do_cancel()`.

This changes the em_x270_usb_hub_init() function to bail out
if it fails, and changes the pxamci_platform_data->setpower
callback so that the a failed em_x270_mci_setpower call
can be propagated by the pxamci driver into the mmc core.

sd_prep_fn will allocate a larger CDB for the command via mempool_alloc
for devices using DIF type 2 protection. This CDB was being freed
in sd_done, which results in a kernel crash if the command is retried
due to a UNIT ATTENTION. This change moves the code to free the larger
CDB into sd_unprep_fn instead, which is invoked after the request is
complete.
It is no longer necessary to call scsi_print_command separately for
this case as the ->cmnd will no longer be NULL in the normal code path.
Also removed conditional test for DIF type 2 when freeing the larger
CDB because the protection_type could have been changed via sysfs while
the command was executing.

This commit fixes a race condition in the isci driver abort task and SSP
device task management path. The race is caused when an I/O termination
in the SCU hardware is necessary because of an SSP target timeout condition,
and the check of the I/O end state races against the HW-termination-driven
end state. The failure of the race meant that no TMF was sent to the device
to clean-up the pending I/O.

drm/i915: fixup 12bpc hdmi dotclock handling
I've errornously claimed that we don't yet support the hdmi 1.4
dotclocks > 225 MHz on Haswell. But a bug report and a closer look at
the wrpll table showed that we've supported port clocks up to 300MHz.
With the new code to dynamically compute wrpll limits we should have
no issues going up to the full 340 MHz range of hdmi 1.4, so let's
just use that to fix this regression. That'll allow 4k over hdmi for
free!
v2: Drop the random hunk that somehow slipped in.
v3: Cantiga has the original HDMI dotclock limit of 165MHz. And also
patch up the mode filtering. To do so extract the dotclock limits into
a little helper function.
v4: Use 300MHz (from Bspec) instead of 340MHz (upper limit for hdmi
1.3), apparently hw is not required to be able to drive the highest
dotclocks. Suggested by Damien.

Change to using max P-state instead of max turbo P-state. This
change resolves two issues.
On a quiet system intel_pstate can fail to respond to a load change.
On CPU SKUs that have a limited number of P-states and no turbo range
intel_pstate fails to select the highest available P-state.
This change is suitable for stable v3.9+

Pull thermal management fixes from Zhang Rui:
"These are fixes collected over the last week, they fixes several
problems caused by the x86_pkg_temp_thermal introduced in 3.11-rc1.
Specifics:
- the x86_pkg_temp_thermal driver causes crash on systems with no
package MSR support as there is a bug in the logic to check
presence of DTHERM and PTS feature together. Added a change so
that when there is no PTS support, module doesn't get loaded.
- fix krealloc() misuse in pkg_temp_thermal_device_add().
If krealloc() returns NULL, it doesn't free the original. Thus if
we want to exit because of the krealloc() failure, we must make
sure the original one is freed.
- The error code path of the x86 package temperature thermal driver's
initialization routine makes an unbalanced call to
get_online_cpus(), which causes subsequent CPU offline operations,
and consequently system suspend, to permanently block in
cpu_hotplug_begin() on systems where get_core_online() returns an
error code.
Remove the extra get_online_cpus() to fix the problem"

circumstances the driver pull request would be late. Now it looks
like -rc2 late... On the plus side, apart form the rsxx update, these

they are fixes and not features. So even though things are late, it's

sata_inic162x never reached a state where it's reliable enough for
production use and data corruption is a relatively common occurrence.
Make the driver generate warning about the issues and mark the Kconfig
option as experimental.
If the situation doesn't improve, we'd be better off making it depend
on CONFIG_BROKEN. Let's wait for several cycles and see if the kernel
message draws any attention.

Noticed that my old Radeon 7500 hung after printing
drm: GPU not posted. posting now...
when it wasn't selected as the primary card the BIOS. Some digging
revealed that it was hanging in combios_parse_mmio_table() while
parsing the ASIC INIT 3 table. Looking at the BIOS ROM for the card,
it becomes obvious that there is no ASIC INIT 3 table in the BIOS.
The code is just processing random garbage. No surprise it hangs!
Why do I say that there is no ASIC INIT 3 table is the BIOS? This
table is found through the MISC INFO table. The MISC INFO table can
be found at offset 0x5e in the COMBIOS header. But the header is
smaller than that. The COMBIOS header starts at offset 0x126. The
standard PCI Data Structure (the bit that starts with 'PCIR') lives at
offset 0x180. That means that the COMBIOS header can not be larger
than 0x5a bytes and therefore cannot contain a MISC INFO table.
I looked at a dozen or so BIOS images, some my own, some downloaded from:
<http://www.techpowerup.com/vgabios/index.php?manufacturer=ATI&page=1>
It is fairly obvious that the size of the COMBIOS header can be found
at offset 0x6 of the header. Not sure if it is a 16-bit number or
just an 8-bit number, but that doesn't really matter since the tables
seems to be always smaller than 256 bytes.
So I think combios_get_table_offset() should check if the requested
table is present. This can be done by checking the offset against the
size of the header. See the diff below. The diff is against the WIP
OpenBSD codebase that roughly corresponds to Linux 3.8.13 at this
point. But I don't think this bit of the code changed much since
then.
For what it is worth:

Hello,
got another card with "too bright" problem:
Sapphire Radeon VE 7000 DDR (VGA+S-Video)
lspci -vnn:
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV100 QY [Radeon 7000/VE] [1002:5159] (prog-if 00 [VGA controller])
Subsystem: PC Partner Limited Sapphire Radeon VE 7000 DDR [174b:7c28]
The patch below fixes the problem for this card.
But I don't like the blacklist, couldn't some heuristic be used instead?
The interesting thing is that the manufacturer is the same as the other card
needing the same quirk. I wonder how many different types are broken this way.
The "wrong" ps2_pdac_adj value that comes from BIOS on this card is 0x300.
====================

The PFC pinctrl driver on sh73a0 is also regiatering a VccQ regulator for
SDHI0. However, its consumers list only included the platform-data based
SDHI device name. When booted with DT SDHI0 couldn't enable VccQ and
therefore was unusable. Fix this by adding a consumer with DT-based name.
