Haiyang Zhang f45708209d hyperv: Fix the NETIF_F_SG flag setting in netvsc
SG mode is not currently supported by netvsc, so remove this flag for now.
Otherwise, it will be unconditionally enabled by commit ec5f061564
    "Kill link between CSUM and SG features"
Previously, the SG feature is disabled because CSUM is not set here.

Greg Kroah-Hartman 78077256bc The first round of IIO fixes for the 3.11 cycle.
This set is larger than I would like, partly due to my lack of review
 time in the weeks before the merge window and partly because a
 couple of large drivers and the subsystem as a whole seem to be
 getting a lot more exposure and testing recently.
 
 1) A long term bug in trigger handling gave a double free of the device.
 
 2) Wrong return value handling means offsets are ignored in
    iio_convert_raw_to_processed_unlocked.
 
 3) The iio_channel_has_info utility function was incorrectly updated
    during the recent info_mask split, this is now fixed.
 
 4) mxs-lradc has a couple of little fixes.
 
 5) A couple of missing .driver_module entries meant that drivers
    could be removed from underneath their users.
 
 6) Error path fixes for ad7303 and lis3l02dq.
 
 7) The scale value for presure in the lps331ap driver was out by
    a factor of 100.

Greg Kroah-Hartman ade7615de0 staging: csr: remove driver
This driver is not being updated as the specifications are not able to
be gotten from CSR or anyone else.  Without those, getting this driver
into proper mergable shape is going to be impossible.  So remove the
driver from the tree.

If the specifications ever become available, this patch can be reverted
and the driver fixed up properly.

Dave Airlie 6bd2cab2c1 Merge tag 'drm-intel-fixes-2013-07-11' of git://people.freedesktop.org/~danvet/drm-intel
One feature latecomer, I've forgotten to merge the patch to reeanble the
Haswell power well feature now that the audio interaction is fixed up.
Since that was the only unfixed issue with it I've figured I could throw
it in a bit late, and it's trivial to revert in case I'm wrong.

Otherwise all bug/regression fixes:
- Fix status page reinit after gpu hangs, spotted by more paranoid igt
  checks.
- Fix object list walking fumble regression in the shrinker (only the
  counting part, the actual shrinking code was correct so no Oops
  potential), from Xiong Zhang.
- Fix DP 1.2 bw limits (Imre).
- Restore legacy forcewake on ivb, too many broken biosen out there. We
  dump a warn though that recent userspace might fall over with that
  config (Guenter Roeck).
- Patch up the gen2 cs tlb w/a.
- Improve the fence coherency w/a now that we have a better understanding
  what's going on. The removed wbinvd+ipi should make -rt folks happy. Big
  thanks to Jon Bloomfield for figuring this out, patches from Chris.
- Fix write-read race when switching ring (Chris). Spotted with code
  inspection, but now we also have an igt for it.

There's an ugly regression we're still working on introduced between
3.10-rc7 and 3.10.0. Unfortunately we can't just revert the offender since
that one fixes another regression :( I've asked Steven to include my
-fixes branch into linux-next to prevent such fallout in the future,
hopefully.

Srivatsa S. Bhat e8d05276f2 cpufreq: Revert commit 2f7021a8 to fix CPU hotplug regression
commit 2f7021a8 "cpufreq: protect 'policy->cpus' from offlining
during __gov_queue_work()" caused a regression in CPU hotplug,
because it lead to a deadlock between cpufreq governor worker thread
and the CPU hotplug writer task.

[   60.280582] smpboot: CPU 1 is now offline

The intention of that commit was to avoid warnings during CPU
hotplug, which indicated that offline CPUs were getting IPIs from the
cpufreq governor's work items.  But the real root-cause of that
problem was commit a66b2e5 (cpufreq: Preserve sysfs files across
suspend/resume) because it totally skipped all the cpufreq callbacks
during CPU hotplug in the suspend/resume path, and hence it never
actually shut down the cpufreq governor's worker threads during CPU
offline in the suspend/resume path.

Reflecting back, the reason why we never suspected that commit as the
root-cause earlier, was that the original issue was reported with
just the halt command and nobody had brought in suspend/resume to the
equation.

The reason for _that_ in turn, as it turns out, is that earlier
halt/shutdown was being done by disabling non-boot CPUs while tasks
were frozen, just like suspend/resume....  but commit cf7df378a
(reboot: migrate shutdown/reboot to boot cpu) which came somewhere
along that very same time changed that logic: shutdown/halt no longer
takes CPUs offline.  Thus, the test-cases for reproducing the bug
were vastly different and thus we went totally off the trail.

Overall, it was one hell of a confusion with so many commits
affecting each other and also affecting the symptoms of the problems
in subtle ways.  Finally, now since the original problematic commit
(a66b2e5) has been completely reverted, revert this intermediate fix
too (2f7021a8), to fix the CPU hotplug deadlock.  Phew!

Sarveshwar Bandi 52fe29e4bb be2net: Fix to avoid hardware workaround when not needed
Hardware workaround requesting hardware to skip vlan insertion is necessary

Neil Horman 584ec43553 atl1e: unmap partially mapped skb on dma error and free skb
Ben Hutchings pointed out that my recent update to atl1e
in commit 352900b583
("atl1e: fix dma mapping warnings") was missing a bit of code.

Specifically it reset the hardware tx ring to its origional state when
we hit a dma error, but didn't unmap any exiting mappings from the
operation.  This patch fixes that up.  It also remembers to free the
skb in the event that an error occurs, so we don't leak.  Untested, as
I don't have hardware.  I think its pretty straightforward, but please
review closely.

We should be using groups, not attribute lists, for classes to allow
subdirectories, and soon, binary files.  Groups are just more flexible
overall, so add them.

The dev_attrs list will go away after all in-kernel users are converted

Paul Gortmaker a83048ebd4 drivers: delete __cpuinit usage from all remaining drivers files
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

This removes all the remaining one-off uses of the __cpuinit macros
from all C files in the drivers/* directory.

Paul Bolle 4a6c41083d cpufreq: s3c24xx: rename CONFIG_CPU_FREQ_S3C24XX_DEBUGFS
The Kconfig symbol CPU_FREQ_S3C24XX_DEBUGFS was renamed to
ARM_S3C24XX_CPUFREQ_DEBUGFS in commit f023f8dd59 ("cpufreq: s3c24xx:
move cpufreq driver to drivers/cpufreq"). But that commit missed one
instance of its macro CONFIG_CPU_FREQ_S3C24XX_DEBUGFS. Rename it too.

Srivatsa S. Bhat aae760ed21 cpufreq: Revert commit a66b2e to fix suspend/resume regression
commit a66b2e (cpufreq: Preserve sysfs files across suspend/resume)
has unfortunately caused several things in the cpufreq subsystem to
break subtly after a suspend/resume cycle.

The intention of that patch was to retain the file permissions of the
cpufreq related sysfs files across suspend/resume.  To achieve that,
the commit completely removed the calls to cpufreq_add_dev() and
__cpufreq_remove_dev() during suspend/resume transitions.  But the
problem is that those functions do 2 kinds of things:
  1. Low-level initialization/tear-down that are critical to the
     correct functioning of cpufreq-core.
  2. Kobject and sysfs related initialization/teardown.

Ideally we should have reorganized the code to cleanly separate these
two responsibilities, and skipped only the sysfs related parts during
suspend/resume.  Since we skipped the entire callbacks instead (which
also included some CPU and cpufreq-specific critical components),
cpufreq subsystem started behaving erratically after suspend/resume.

So revert the commit to fix the regression.  We'll revisit and address
the original goal of that commit separately, since it involves quite a
bit of careful code reorganization and appears to be non-trivial.

(While reverting the commit, note that another commit f51e1eb
 (cpufreq: Fix cpufreq regression after suspend/resume) already
 reverted part of the original set of changes.  So revert only the
 remaining ones).

Toshi Kani d19f503e22 ACPI / memhotplug: Fix a stale pointer in error path
device->driver_data needs to be cleared when releasing its data,
mem_device, in an error path of acpi_memory_device_add().

The function evaluates the _CRS of memory device objects, and fails
when it gets an unexpected resource or cannot allocate memory.  A
kernel crash or data corruption may occur when the kernel accesses
the stale pointer.

An ACPI_NOTIFY_BUS_CHECK notification means that we should scan the
entire namespace starting from the given handle even if the device
represented by that handle is present (other devices below it may
just have appeared).

For this reason, modify acpi_scan_bus_device_check() to always run
acpi_bus_scan() if the notification being handled is of type
ACPI_NOTIFY_BUS_CHECK.

Rafael J. Wysocki 3a391a3959 ACPI / scan: Do not try to attach scan handlers to devices having them
In acpi_bus_device_attach(), if there is an ACPI device object
for the given handle and that device object has a scan handler
attached to it already, there's nothing more to do for that handle.
Moreover, if acpi_scan_attach_handler() is called then, it may
execute the .attach() callback of the ACPI scan handler already
attached to the device object and that may lead to interesting
breakage.

For this reason, make acpi_bus_device_attach() return success
immediately when the handle's device object has a scan handler
attached to it.

The usual straighforward failure to check for dma_mapping_error after a map
operation is completed.

This patch should fix it, the reporter wandered off after filing this bz:
https://bugzilla.redhat.com/show_bug.cgi?id=954170

and I don't have hardware to test, but the fix is pretty straightforward, so I
figured I'd post it for review.

Base on cdc_ether, add the mii functions for RTL8152 and RTL8153.
The RTL8152 and RTL8153 support ECM mode which use the driver of
cdc_ether. Add the mii functions. Then, the basic PHY access is

Russell King 6910ceb5ca Watchdog: fix clearing of the watchdog interrupt
The bits in BRIDGE_CAUSE are documented as RW0C - read, write 0 to
clear.  If we read the register, mask off the watchdog bit, and
write it back, we're actually clearing every interrupt which wasn't
pending at the time we read the register - and that is racy.

Fix this to only write ~WATCHDOG_BIT to the register, which means
we write as zero only the watchdog bit.

   - Make persistent reservations APTPL buffer allocated on-demand, and
     drop per t10_reservation buffer.  (grover)
   - Make virtual LUN=0 a NULLIO device, and skip allocation of NULLIO
     device pages (grover)

     access of ->t_state_lock is WRITE I/O submission fast-path.  (nab)
   - Drop unnecessary CMD_T_DEV_ACTIVE check from
     transport_lun_remove_cmd to avoid extra access of ->t_state_lock in
     release fast-path.  (nab)
   - Avoid extra t_state_lock access in __target_execute_cmd fast-path
     (nab)
   - Drop unnecessary vhost-scsi wait_for_tasks=true usage +
     ->t_state_lock access in release fast-path.  (nab)
   - Convert vhost-scsi to use modern se_cmd->cmd_kref
     TARGET_SCF_ACK_KREF usage (nab)
   - Add tracepoints for SCSI commands being processed (roland)
   - Refactoring of iscsi-target handling of ISCSI_OP_NOOP +
     ISCSI_OP_TEXT to be transport independent (nab)
   - Add iscsi-target SendTargets=$IQN support for in-band discovery

Viresh Kumar 6e63a3a294 watchdog: delete mpcore_wdt driver
Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu
interrupt (usually interrupt #30), and the GIC configuration should flag it as
such. With this setup, request_irq() should fail, and the right API is
request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq().

Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the
right CPU.

There are no users of this driver since a long time and it makes more sense to
get rid of it as nobody is looking to fix it.

In case somebody wakes up after this has been removed and needs it, please
revert this driver and pick these updates (These were never pushed to mainline):

Hector Palacios fcf95670fd watchdog: core: don't try to stop device if not running
A watchdog device may be stopped from userspace using WDIOC_SETOPTIONS
ioctl and flag WDIOS_DISABLECARD. If the device is closed after this
operation, watchdog_release() is called and status bits checked for
stopping it. Besides, if the device has not been unregistered a critical
message "watchdog did not stop!" is printed, although the ioctl may have
successfully stopped it already.

Without the patch a user application sample code like this will successfully
stop the watchdog, but the kernel will output the message
"watchdog did not stop!":

	wd_fd = open("/dev/watchdog", O_RDWR);

	flags = WDIOS_DISABLECARD;
	ioctl(wd_fd, WDIOC_SETOPTIONS, &flags);

	close(wd_fd);
