a829abf8da ARM: pxa: propagate errors from regulator_enable() to pxamci
The em_x270_mci_setpower() and em_x270_usb_hub_init() functions
call regulator_enable(), which may return an error that must
be checked.

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.

e4daf1ffbe nfsd: nfsd_open: when dentry_open returns an error do not propagate as struct file
The following call chain:
------------------------------------------------------------
nfs4_get_vfs_file
- nfsd_open
  - dentry_open
    - do_dentry_open
      - __get_file_write_access
        - get_write_access
          - return atomic_inc_unless_negative(&inode->i_writecount) ? 0 : -ETXTBSY;
------------------------------------------------------------

can result in the following state:
------------------------------------------------------------
struct nfs4_file {
...
  fi_fds = {0xffff880c1fa65c80, 0xffffffffffffffe6, 0x0},
  fi_access = {{
      counter = 0x1
    }, {
      counter = 0x0
    }},
...
------------------------------------------------------------

1) First time around, in nfs4_get_vfs_file() fp->fi_fds[O_WRONLY] is
NULL, hence nfsd_open() is called where we get status set to an error
and fp->fi_fds[O_WRONLY] to -ETXTBSY. Thus we do not reach
nfs4_file_get_access() and fi_access[O_WRONLY] is not incremented.

2) Second time around, in nfs4_get_vfs_file() fp->fi_fds[O_WRONLY] is
NOT NULL (-ETXTBSY), so nfsd_open() is NOT called, but
nfs4_file_get_access() IS called and fi_access[O_WRONLY] is incremented.
Thus we leave a landmine in the form of the nfs4_file data structure in
an incorrect state.

3) Eventually, when __nfs4_file_put_access() is called it finds
fi_access[O_WRONLY] being non-zero, it decrements it and calls
nfs4_file_put_fd() which tries to fput -ETXTBSY.

085b513f97 [SCSI] sd: fix crash when UA received on DIF enabled device
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.

commit b29900e6 (AHCI: Make distinct names for ports in /proc/interrupts)
introuded a regression, which resulted Null pointer dereference for achi
host with dummy ports. For ahci ports, when the port is dummy port, its
private_data will be NULL, as ata_dummy_port_ops doesn't support ->port_start.

changes in v2: use pp to check dummy ports, update comments

96f15f2903 [SCSI] isci: Fix a race condition in the SSP task management path
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.

82b2f495fb arm64: virt: ensure visibility of __boot_cpu_mode
Secondary CPUs write to __boot_cpu_mode with caches disabled, and thus a
cached value of __boot_cpu_mode may be incoherent with that in memory.
This could lead to a failure to detect mismatched boot modes.

This patch adds flushing to ensure that writes by secondaries to
__boot_cpu_mode are made visible before we test against it.

89c8233f82 drm/gem: simplify object initialization
drm_gem_object_init() and drm_gem_private_object_init() do exactly the
same (except for shmem alloc) so make the first use the latter to reduce
code duplication.

Also drop the return code from drm_gem_private_object_init(). It seems
unlikely that we will extend it any time soon so no reason to keep it
around. This simplifies code paths in drivers, too.

Last but not least, fix gma500 to call drm_gem_object_release() before
freeing objects that were allocated via drm_gem_private_object_init().
That isn't actually necessary for now, but might be in the future.

7d148ef51a drm/i915: fix hdmi portclock limits
In

commit 325b9d0488
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Fri Apr 19 11:24:33 2013 +0200

    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.

6287e73198 ARM: footbridge: fix overlapping PCI mappings
Commit 8ef6e6201b (ARM: footbridge: use
fixed PCI i/o mapping) broke booting on my netwinder.  Before that,
everything boots fine.  Since then, it crashes on boot.

With earlyprintk, I see it BUG-ing like so:
kernel BUG at lib/ioremap.c:27!
Internal error: Oops - BUG: 0 [#1] ARM
...
[<c0139b54>] (ioremap_page_range+0x128/0x154) from [<c02e6a6c>] (dc21285_setup+0xd0/0x114)

[<c02e793c>] (netwinder_pci_init+0xc/0x18) from [<c02e27d0>] (do_one_initcall+0xb4/0x180)
...

Russell points out it's because of overlapping PCI mappings that was
added with the aforementioned commit.  Rob thought the code would re-use
the static mapping, but that turns out to not be the case and instead
hits the BUG further down.

After deleting this hunk as suggested by Russel, the system boots up fine
again and all my PCI devices work (IDE, ethernet, the DC21285).

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"
