67236c44741e250199ccd77f1115568e68cf8848 upstream.
This patch fixes a bug in target-core where unsupported WRITE_SAME ops
from a target_check_write_same_discard() failure was incorrectly
returning CHECK_CONDITION w/ TCM_INVALID_CDB_FIELD sense data.
This was causing some clients to not properly fall back, so go ahead
and use the correct TCM_UNSUPPORTED_SCSI_OPCODE sense for this case.

With runtime PM, if the ethernet cable is disconnected, the device is
transitioned to D3 state to conserve energy. If the system is shutdown
in this state, any register accesses in rtl_shutdown are dropped on
the floor. As the device was programmed by .runtime_suspend() to wake
on link changes, it is thus brought back up as soon as the link recovers.
Resuming every suspended device through the driver core would slow things
down and it is not clear how many devices really need it now.
Original report and D0 transition patch by Sameer Nanda. Patch has been
changed to comply with advices by Rafael J. Wysocki and the PM folks.

mplayer -vo fbdev tries to create a screen that is twice as tall as the

users, only sufficient memory is allocated and mapped to satisfy the
smallest framebuffer and the virtual size is no larger than the actual.
For these users, we should therefore reject any userspace request to
create a screen that requires a buffer larger than the framebuffer

BugLink: http://bugs.launchpad.net/bugs/981162
commit
12b5da349a8b94c9dbc3430a6bc42eabd9eaf50b upstream.
When reading the trace file, the records of each of the per_cpu buffers
are examined to find the next event to print out. At the point of looking
at the event, the size of the event is recorded. But if the first event is
chosen, the other events in the other CPU buffers will reset the event size
that is stored in the iterator descriptor, causing the event size passed to
the output functions to be incorrect.
In most cases this is not a problem, but for the case of stack traces, it
is. With the change to the stack tracing to record a dynamic number of
back traces, the output depends on the size of the entry instead of the
fixed 8 back traces. When the entry size is not correct, the back traces
would not be fully printed.
Note, reading from the per-cpu trace files were not affected.

irq_move_masked_irq() checks the return code of
chip->irq_set_affinity() only for 0, but IRQ_SET_MASK_OK_NOCOPY is
also a valid return code, which is there to avoid a redundant copy of
the cpumask. But in case of IRQ_SET_MASK_OK_NOCOPY we not only avoid
the redundant copy, we also fail to adjust the thread affinity of an
eventually threaded interrupt handler.
Handle IRQ_SET_MASK_OK (==0) and IRQ_SET_MASK_OK_NOCOPY(==1) return
values correctly by checking the valid return values seperately.

ACPI: Do cpufreq clamping for throttling per package v2
BugLink: http://bugs.launchpad.net/bugs/981162
commit
2815ab92ba3ab27556212cc306288dc95692824b upstream.
On Intel CPUs the processor typically uses the highest frequency
set by any logical CPU. When the system overheats
Linux first forces the frequency to the lowest available one
to lower the temperature.
However this was done only per logical CPU, which means all
logical CPUs in a package would need to go through this before
the frequency is actually lowered.
Worse this delay actually prevents real throttling, because
the real throttle code only proceeds when the lowest frequency
is already reached.
So when a throttle event happens force the lowest frequency
for all CPUs in the package where it happened. The per CPU
state is now kept per package, not per logical CPU. An alternative
would be to do it per cpufreq unit, but since we want to bring
down the temperature of the complete chip it's better
to do it for all.
In principle it may even make sense to do it for all CPUs,
but I kept it on the package for now.
With this change the frequency is actually lowered, which
in terms also allows real throttling to proceed.
I also removed an unnecessary per cpu variable initialization.

third argument of "mtd_device_parse_register()" changed from start address
of the MTD device to a pointer to a struct.
The "ixp4xx_flash_probe()" function was not converted properly, causing
an oops during boot.
This patch fixes the problem by filling the needed information into a
"struct mtd_part_parser_data" and passing it to
"mtd_device_parse_register()".

UBUNTU: SAUCE: staging: comedi: Add module parameters for default buffer size
BugLink: http://bugs.launchpad.net/bugs/981234
For comedi subdevices that support asynchronous transfer commands, the
initial buffer size and maximum buffer size for the transfer are both
set to 64 KiB when the comedi device is "attached" to the hardware
device. For many applications with reasonable fast sample rates and
slow user-space (e.g. Python) these sizes are a bit too small.
A task with CAP_SYS_ADMIN privileges can change the maximum buffer size
for a comedi subdevice with an ioctl call or by writing to a device
attribute file in sysfs, but that's not very convenient. For comedi
devices attached during system startup, this could be done by a start-up
script, but for hot-plugged devices it would require scripts run by udev
rules, etc.
Rather than use hardwired values, this patch introduces a couple of
module parameters to set the defaults for the initial buffer size
(comedi_default_buf_size_kb) and maximum buffer size
(comedi_default_buf_maxsize_kb). These values are applied in place of
the previous hard-wired values when the comedi device is "attached".
The module parameter values are in units of KiB for consistency with the
existing device attribute files.

On the other hand, the FSP found on UX21/31 doesn't have hardware capability
register other than PnP ID, which means that we'll have to figure out an
alternative approach to identify such pad correctly; otherwise, blindly
adding INPUT_PROP_BUTTONPAD property may compatability issues amongst
existing FSPs.

kmsg_dump: don't run on non-error paths by default
BugLink: http://bugs.launchpad.net/bugs/944772
Since commit
04c6862c055f ("kmsg_dump: add kmsg_dump() calls to the
reboot, halt, poweroff and emergency_restart paths"), kmsg_dump() gets
run on normal paths including poweroff and reboot.
This is less than ideal given pstore implementations that can only
represent single backtraces, since a reboot may overwrite a stored oops
before it's been picked up by userspace. In addition, some pstore
backends may have low performance and provide a significant delay in
reboot as a result.
This patch adds a printk.always_kmsg_dump kernel parameter (which can also
be changed from userspace). Without it, the code will only be run on
failure paths rather than on normal paths. The option can be enabled in
environments where there's a desire to attempt to audit whether or not a
reboot was cleanly requested or not.

NLS: improve UTF8 -> UTF16 string conversion routine
The utf8s_to_utf16s conversion routine needs to be improved. Unlike
its utf16s_to_utf8s sibling, it doesn't accept arguments specifying
the maximum length of the output buffer or the endianness of its
16-bit output.
This patch (as1501) adds the two missing arguments, and adjusts the
only two places in the kernel where the function is called. A
follow-on patch will add a third caller that does utilize the new
capabilities.
The two conversion routines are still annoyingly inconsistent in the
way they handle invalid byte combinations. But that's a subject for a

net/hyperv: Fix data corruption in rndis_filter_receive()
Limiting the memcpy to be the sizeof(struct rndis_message) can truncate
the message if there are Per-Packet-Info or Out-of-Band data.
In my earlier patch (commit
45326342), the unnecessary kmap_atomic and
kunmap_atomic surrounding this memcpy have been removed because the memory
in the receive buffer is always mapped. This memcpy is not necessary
either. To fix the bug, I removed the memcpy.

drivers: hv: Increase the number of VCPUs supported in the guest
The current code arbirarily limited the number of CPUs the guest could have.
Change that so that we can support the maximum number of CPUs the guest can
support. While we use NR_CPUS to size the per-cpu state all we are allocating
based on NR_CPUS are the pointers to per-cpu state that will be allocatted in
the context of the initializing CPU. This patch triggers a checkpatch warning
for the usage of NR_CPU and since all we are allocating a couple of pointers
per CPU, it should be ok.

drm/i915: Sanitize BIOS debugging bits from PIPECONF
Quoting the BSpec from time immemorial:
PIPEACONF, bits 28:27: Frame Start Delay (Debug)
Used to delay the frame start signal that is sent to the display planes.
Care must be taken to insure that there are enough lines during VBLANK
to support this setting.
An instance of the BIOS leaving these bits set was found in the wild,
where it caused our modesetting to go all squiffy and skewiff.

This reverts commmit
d4b74bf07873da2e94219a7b67a334fc1c3ce649 which
reverted the origin fix
fb8b5a39b6310379d7b54c0c7113703a8eaf4a57.
We have at least 3 different bug reports that this fixes things and no
indication what is exactly wrong with this. So try again.
To make matters slightly more fun, the commit itself was cc: stable
whereas the revert has not been.
According to Peter Clifton he discussed this with Zhao Yakui and this
seems to be in contradiction of the GM45 PRM, but rumours have it that
this is how the BIOS does it ... let's see.
