1e207eb1c3 Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
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."

This contains unexpectedly many changes in a wide range due to the
 fixes for races at disconnection of USB audio devices.  In the end,
 we end up covering fairly core parts of sound subsystem.

8280960181 ARM: OMAP: Remove cpu_is_omap usage from plat-omap/dma.c
This code will be eventually in drivers, and for the
code in the drivers we don't want to have any cpu_is_omap
usage. Those macros should be private to arch/arm/mach-omap1

To fix this, let's move the define for dma_omap2plus()
to dma-omap.h, and use the existing dma_attr passed in
the platform_data as the revision registers are what they
are.

Note that we can now also remove the relative includes
introduced by the recent clean-up patches.

87da7e66a4 KVM: x86: fix vcpu->mmio_fragments overflow
After commit b3356bf0db (KVM: emulator: optimize "rep ins" handling),
the pieces of io data can be collected and write them to the guest memory
or MMIO together

Unfortunately, kvm splits the mmio access into 8 bytes and store them to
vcpu->mmio_fragments. If the guest uses "rep ins" to move large data, it
will cause vcpu->mmio_fragments overflow

The bug can be exposed by isapc (-M isapc):

[23154.818733] general protection fault: 0000 [#1] SMP DEBUG_PAGEALLOC
[ ......]
[23154.858083] Call Trace:
[23154.859874]  [<ffffffffa04f0e17>] kvm_get_cr8+0x1d/0x28 [kvm]

[23154.863604]  [<ffffffffa04f5a1a>] ? kvm_arch_vcpu_load+0x17b/0x180 [kvm]

Actually, we can use one mmio_fragment to store a large mmio access then
split it when we pass the mmio-exit-info to userspace. After that, we only
need two entries to store mmio info for the cross-mmio pages access

324d003b0c NFS: add nfs_sb_deactive_async to avoid deadlock
Use nfs_sb_deactive_async instead of nfs_sb_deactive when in a workqueue
context.  This avoids a deadlock where rpc_shutdown_client loops forever
in a workqueue kworker context, trying to kill all RPC tasks associated with
the client, while one or more of these tasks have already been assigned to the
same kworker (and will never run rpc_exit_task).

This approach is needed because RPC tasks that have already been assigned
to a kworker by queue_work cannot be canceled, as explained in the comment
for workqueue.c:insert_wq_barrier.

97a5486826 nfs: Show original device name verbatim in /proc/*/mount{s,info}
Since commit c7f404b ('vfs: new superblock methods to override
/proc/*/mount{s,info}'), nfs_path() is used to generate the mounted
device name reported back to userland.

nfs_path() always generates a trailing slash when the given dentry is
the root of an NFS mount, but userland may expect the original device
name to be returned verbatim (as it used to be).  Make this
canonicalisation optional and change the callers accordingly.

acce94e68a nfsv3: Make v3 mounts fail with ETIMEDOUTs instead EIO on mountd timeouts
In very busy v3 environment, rpc.mountd can respond to the NULL
procedure but not the MNT procedure in a timely manner causing
the MNT procedure to time out. The problem is the mount system
call returns EIO which causes the mount to fail, instead of
ETIMEDOUT, which would cause the mount to be retried.

This patch sets the RPC_TASK_SOFT|RPC_TASK_TIMEOUT flags to
the rpc_call_sync() call in nfs_mount() which causes
ETIMEDOUT to be returned on timed out connections.

8d96b10639 NFS: fix bug in legacy DNS resolver.
The DNS resolver's use of the sunrpc cache involves a 'ttl' number
(relative) rather that a timeout (absolute).  This confused me when
I wrote
  commit c5b29f885a
     "sunrpc: use seconds since boot in expiry cache"

and I managed to break it.  The effect is that any TTL is interpreted
as 0, and nothing useful gets into the cache.

This patch removes the use of get_expiry() - which really expects an
expiry time - and uses get_uint() instead, treating the int correctly
as a ttl.

This fixes a regression that has been present since 2.6.37, causing
certain NFS accesses in certain environments to incorrectly fail.

John W. Linville says:

====================
This is a batch of fixes intended for 3.7...

The biggest portion of this is a pull request from Johannes Berg:

"Please pull my mac80211.git tree per below to get a number of fixes. I
have included a patch from Antonio to fix a memcpy overrun, Felix's
patches for the antenna gain/tx power issues, a few mesh-related fixes
from Javier for mac80211 and my own patches to not access data that
might not be present in an skb at all as well as a patch (the duplicate
IE check one) to make mac80211 forward-compatible with potential future
spec extensions that use the same IE multiple times.

It's a bit bigger than I'd like maybe, but I think all of these are
worthwhile fixes at this point."

In addition...

Felix Fietkau fixes an ath9k use-after-free issue.

Stanislaw Gruszka adds a valid value check to rt2800.

Sven Eckelmann adds a check to only check a TID value in a BlockAck, for
frames that could be either a BlockAck or a normal Ack.

399f11c3d8 NFS: Wait for session recovery to finish before returning
Currently, we will schedule session recovery and then return to the
caller of nfs4_handle_exception.  This works for most cases, but causes
a hang on the following test case:

	Client				Server
	------				------
	Open file over NFS v4.1
	Write to file
					Expire client
	Try to lock file

The server will return NFS4ERR_BADSESSION, prompting the client to
schedule recovery.  However, the client will continue placing lock
attempts and the open recovery never seems to be scheduled.  The
simplest solution is to wait for session recovery to run before retrying
the lock.

95a7d76897 xen/mmu: Use Xen specific TLB flush instead of the generic one.
As Mukesh explained it, the MMUEXT_TLB_FLUSH_ALL allows the
hypervisor to do a TLB flush on all active vCPUs. If instead
we were using the generic one (which ends up being xen_flush_tlb)
we end up making the MMUEXT_TLB_FLUSH_LOCAL hypercall. But
before we make that hypercall the kernel will IPI all of the
vCPUs (even those that were asleep from the hypervisor
perspective). The end result is that we needlessly wake them
up and do a TLB flush when we can just let the hypervisor
do it correctly.

This patch gives around 50% speed improvement when migrating
idle guest's from one host to another.

44c91697fb drm/exynos: fix display on issue
When crtc_funcs->dpms callback is called, exynos_crtc->dpms
and exynos_encoder->dpms are changed to new mode. But if user
requests dpms mode operation, OFF -> ON, when crtc's dpms callback
is called, exynos_encoder->dpms is also changed to ON. This
makes encoder's dpms callback call be ignored so display power
couldn't become on again.

This patch removes exynos_encoder->dpms changing and adds 'updated'
variable to exynos_drm_encoder structure to avoid duplicated overlay
updating.

Fix maxcontacts problem for PWT GeneralTouch multi-touchscreen.

Our device didn't contain HID_DG_CONTACTMAX usage. This usage use to describe
touchscreen's maxcontacts for hid-multitouch.c to get maxcontacts automatic. We
fix the device that driver can get maxcontact from our device, hence it doesn't
need .maxcontact=10. Now there is just one device class can fix all our PWT

3ccc60f9d8 HID: microsoft: fix invalid rdesc for 3k kbd
Microsoft Digital Media Keyboard 3000 has two interfaces, and the
second one has a report descriptor with a bug. The second collection
says:
05 01 -- global; usage page -- 01 -- Generic Desktop Controls
09 80 -- local; usage -- 80 -- System Control
a1 01 -- main; collection -- 01 -- application

85 03 -- global; report ID -- 03
19 00 -- local; Usage Minimum -- 00
29 ff -- local; Usage Maximum -- ff
15 00 -- global; Logical Minimum -- 0
26 ff 00 -- global; Logical Maximum -- ff
81 00 -- main; input

c0 -- main; End Collection

I.e. it makes us think that there are all kinds of usages of system
control. That the keyboard is a not only a keyboard, but also a
joystick, mouse, gamepad, keypad, etc. The same as for the Wireless
Desktop Receiver, this should be Physical Min/Max. So fix that
appropriately.

32ed1911fc Input: tsc40 - remove wrong announcement of pressure support
The tsc40 driver announces it supports the pressure event, but will never
send one. The announcement will cause tslib to wait for such events and
sending all touch events with a pressure of 0. Removing the announcement
will make tslib fall back to emulating the pressure on touch events so
everything works as expected.

08f05c4974 Return the right error value when dup[23]() newfd argument is too large
Jack Lin reports that the error return from dup3() for the RLIMIT_NOFILE
case changed incorrectly after 3.6.

The culprit is commit f33ff9927f ("take rlimit check to callers of
expand_files()") which when it moved the "return -EMFILE" out to the
caller, didn't notice that the dup3() had special code to turn the
EMFILE return into EBADF.

The replace_fd() helper that got added later then inherited the bug too.
