commit d9ad77ebfd3a304306f9f18ff3f9e522da075e27 upstream.
This reverts commit 18b4fada275dd2b6dd9db904ddf70fe39e272222.
This code was correct, apologies to anyone who noticed things broke.
revert contents are different due to another commit in between.

commit 777eb1bf15b8532c396821774bf6451e563438f5 upstream.
A kernel crash is observed when a mounted ext3/ext4 filesystem is
physically removed. The problem is that blk_cleanup_queue() frees up
some resources eg by calling elevator_exit(), which are not checked for
in normal operation. So we should rather move these calls to the
destructor function blk_release_queue() as at that point all remaining
references are gone. However, in doing so we have to ensure that any
externally supplied queue_lock is disconnected as the driver might free
up the lock after the call of blk_cleanup_queue(),

commit 6c80c39d9a6986a566c30d797aae37bfb697eea3 upstream.
If iwl_scan_initiate() fails for any reason,
priv->scan_request and priv->scan_vif are left
dangling. This can lead to a crash later when
iwl_bg_scan_completed() tries to run a pending
scan request.
In practice, this seems to be very rare due to
the STATUS_SCANNING check earlier. That check,
however, is wrong -- it should allow a scan to
be queued when a reset/roc scan is going on.
When a normal scan is already going on, a new
one can't be issued by mac80211, so that code
can be removed completely. I introduced this
bug when adding off-channel support in commit
266af4c745952e9bebf687dd68af58df553cb59d.

iwlagn: do not use interruptible waits
Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.
This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.
Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.
This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD'
I have seen in P2P testing, but it is likely
that there are other errors caused by this.

iwlagn: fix command queue timeout
If the command queue is constantly busy,
which can happen in P2P, the hangcheck
timer will frequently find a command in
it and will eventually reset the device
because nothing sets the timestamp for
this queue when commands are processed.
Fix this by setting the timestamp when
a command completes.
iwlegacy does not support P2P, but this patch fix possible
unneeded hardware resets, hence is needed.

commit 1b9ca0272ffae212e726380f66777b30a56ed7a5 upstream.
Incorrect variable was used in validating the akm_suites array from
NL80211_ATTR_AKM_SUITES. In addition, there was no explicit
validation of the array length (we only have room for
NL80211_MAX_NR_AKM_SUITES).
This can result in a buffer write overflow for stack variables with
arbitrary data from user space. The nl80211 commands using the affected
functionality require GENL_ADMIN_PERM, so this is only exposed to admin
users.

child.
commit 24926dadc41cc566e974022b0e66231b82c6375f upstream.
In an enclosure model where there are chaining expanders to a large body
of storage, it was discovered that libsas, responding to a broadcast
event change, would only revalidate the domain of first child expander
in the list.
The issue is that the pointer value to the discovered source device was
used to break out of the loop, rather than the content of the pointer.
This still remains non-compliant as the revalidate domain code is
supposed to loop through all child expanders, and not stop at the first
one it finds that reports a change count. However, the design of this
routine does not allow multiple device discoveries and that would be a
more complicated set of patches reserved for another day. We are fixing
the glaring bug rather than refactoring the code.

commit 96067723e46b0dd24ae7b934085ab4eff4d26a1b upstream.
Following reports on the list, it looks like the 3e-9xxx driver will leak dma
mappings every time we get a transient queueing error back from the card.
This is because it maps the sg list in the routine that sends the command, but
doesn't unmap again in the transient failure path (even though the command is
sent back to the block layer). Fix by unmapping before returning the status.

commit 4508378b9523e22a2a0175d8bf64d932fb10a67d upstream.
Commit 246e87a93934 ("memcg: fix get_scan_count() for small targets")
fixes the memcg/kswapd behavior against small targets and prevent vmscan
priority too high.
But the implementation is too naive and adds another problem to small
memcg. It always force scan to 32 pages of file/anon and doesn't handle
swappiness and other rotate_info. It makes vmscan to scan anon LRU
regardless of swappiness and make reclaim bad. This patch fixes it by
adjusting scanning count with regard to swappiness at el.
At a test "cat 1G file under 300M limit." (swappiness=20)

the numbers of scanning anon are decreased(as expected), and elapsed time

(*) Because the amount of file-cache is much bigger than anon,
recalaim_stat's rotate-scan counter make scanning files more.

commit 34c869855a28af3c6031d29e2267b5a3cce0d67d upstream.
Attempt to change McBSP CLKS source while another stream is active is not
safe after commit d135865 ("OMAP: McBSP: implement functional clock
switching via clock framework") in 2.6.37.
CLKS parent clock switching using clock framework have to idle the McBSP
before switching and then activate it again. This short break can cause a
DMA transaction error to already running stream which halts and recovers
only by closing and restarting the stream.
This goes more fatal after commit e2fa61d ("OMAP3: l3: Introduce
l3-interconnect error handling driver") in 2.6.39 where l3 driver detects a
severe timeout error and does BUG_ON().
Fix this by not changing any configuration in omap_mcbsp_dai_set_dai_sysclk
if the McBSP is already active. This test should have been here just from
the beginning anyway.

commit caca9510ff4e5d842c0589110243d60927836222 upstream.
In commit a144c6a6c924 ("PM: Print a warning if firmware is requested
when tasks are frozen") we not only printed a warning if somebody tried
to load the firmware when tasks are frozen - we also failed the load.
But that check was done before the check for built-in firmware, and then
when we disallowed usermode helpers during bootup (commit 288d5abec831:
"Boot up with usermodehelper disabled"), that actually means that
built-in modules can no longer load their firmware even if the firmware
is built in too. Which used to work, and some people depended on it for
the R100 driver.
So move the test for usermodehelper_is_disabled() down, to after
checking the built-in firmware.
This should fix:

commit d36b3279e157641c345b12eddb3db78fb42da80f upstream.
Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone
as the physical port and shares the same LUN. This happens due to the fact that
vport destroy and unsolicited ELS are scheduled to run on the same workqueue,
and vport destroy destroys the lport and the unsolicited ELS tries to access
the invalid lport. This patch fixes this issue by maintaining a list of valid
lports and verifying if the lport is valid or not before accessing it.

commit 7625eb2f2fff7bfae41d3119b472c20b48874895 upstream.
Based on earlier patch from Neil Horman <nhorman@tuxdriver.com>
If iSCSI is not supported on a bnx2 device, bnx2_cnic_probe() will
return NULL and the cnic device will not be visible to bnx2i. This
will prevent bnx2i from registering and then unregistering during
cnic_start() and cause the warning message:
bnx2 0003:01:00.1: eth1: Failed waiting for ULP up call to complete

commit db1d350fcb156b58f66a67680617077bcacfe6fc upstream.
During NETDEV_UP, we use symbol_get() to get the net driver's cnic
probe function. This sometimes doesn't work if NETDEV_UP happens
right after NETDEV_REGISTER and the net driver is still running module
init code. As a result, the cnic device may not be discovered. We
fix this by probing on all NETDEV events if the device's netif_running
state is up.

commit 101c40c8cb0d10c30f423805f9f5b7a75956832d upstream.
During iSCSI connection terminations, if the target is also terminating
at about the same time, the firmware may not complete the driver's
request to close or reset the connection. This is fixed by handling
other events (instead of the expected completion event) as an indication
that the driver's request has been rejected.

commit 93736656138e6d2f39f19c1d68f9ef81cfc9dd66 upstream.
We need to keep looping until cnic_get_kcqes() returns 0. cnic_get_kcqes()
returns a maximum of 64 entries. If there are more entries in the queue
and we don't loop back, the remaining entries may not be serviced for a
long time.

commit 3765fefaee2da83f10829fa64a74e6b7360350cb upstream.
Since the d_off in the first dirent for "." (that originates from
the 4th argument "offset" of filldir() for the 2nd dirent for "..")
is wrongly assigned in btrfs_real_readdir(), telldir returns same
offset for different locations.
| # mkfs.btrfs /dev/sdb1
| # mount /dev/sdb1 fs0
| # cd fs0
| # touch file0 file1
| # ../test
| telldir: 0
| readdir: d_off = 2, d_name = "."
| telldir: 2
| readdir: d_off = 2, d_name = ".."
| telldir: 2
| readdir: d_off = 3, d_name = "file0"
| telldir: 3
| readdir: d_off = 2147483647, d_name = "file1"
| telldir: 2147483647
To fix this problem, pass filp->f_pos (which is loff_t) instead.
| # ../test
| telldir: 0
| readdir: d_off = 1, d_name = "."
| telldir: 1
| readdir: d_off = 2, d_name = ".."
| telldir: 2
| readdir: d_off = 3, d_name = "file0"
:
At the moment the "offset" for "." is unused because there is no
preceding dirent, however it is better to pass filp->f_pos to follow
grammatical usage.

commit c37279b92aba2893578f61076cd2eef5c5fa0e99 upstream.
Commit 9676001559fce06e37c7dc230ab275f605556176
("ALSA: fm801: add error handling if auto-detect fails") seems to
break systems that were previously working without a tuner.
As a bonus, this should fix init and cleanup for the case where the
tuner is explicitly disabled.

("ALSA: fm801: add error handling if auto-detect fails") added
incorrect error handling.
Once we have successfully called snd_device_new(), the cleanup
function fm801_free() will automatically be called by snd_card_free()
and we must *not* also call fm801_free() directly.

commit 362e4e49abe53e89d87455dfcd7c1bbaf08a839d upstream.
The Terratec Aureon 5.1 USB sound card support is broken since kernel
2.6.39.
2.6.39 introduced power management support for USB sound cards that added
a probing flag in struct snd_usb_audio.
During the probe of the card it gives following error message :
usb 7-2: new full speed USB device number 2 using uhci_hcd
cannot find UAC_HEADER
snd-usb-audio: probe of 7-2:1.3 failed with error -5
input: USB Audio as
/devices/pci0000:00/0000:00:1d.1/usb7/7-2/7-2:1.3/input/input6
generic-usb 0003:0CCD:0028.0001: input: USB HID v1.00 Device [USB Audio]
on usb-0000:00:1d.1-2/input3
I can not comment about that "cannot find UAC_HEADER" error, but until
2.6.38 the card worked anyway.
With 2.6.39 chip->probing remains 1 on error exit, and any later ioctl
stops in snd_usb_autoresume with -ENODEV.

commit adb091846318f86e4f46c7d6a7b40d2f478abdbe upstream.
64bit PowerPC debuginfo files have an empty function descriptor section.
I hit a SEGV when perf tried to use this section for symbol resolution.
To fix this we need to check the section is valid and we can do this by
checking for type SHT_PROGBITS.

commit a7e6401e19aa54924ab11ee548afaad0a55ffdc6 upstream.
ehci_bios_handoff() is marked __devinit, `ehci_dmi_nohandoff_table' should be
marked __devinitconst, not __initconst. This fixes the following section
mismatch:
WARNING: vmlinux.o(.devinit.text+0x4f08): Section mismatch in reference from the function ehci_bios_handoff() to the variable .init.rodata:ehci_dmi_nohandoff_table
The function __devinit ehci_bios_handoff() references a variable __initconst ehci_dmi_nohandoff_table.
If ehci_dmi_nohandoff_table is only used by ehci_bios_handoff then annotate ehci_dmi_nohandoff_table with a matching annotation.

commit 985af6f70dbb8a33b3af8a7c7df508d924650e37 upstream.
Need the following workaround in the driver for interoperability with
the older Intel SSD drives and any other SATA drive that may exhibit the
same behavior. This is a corner case where SCU speed is limited to
either 3G or 1.5G and the drive has a period of DC idle when it switches
speed during SATA speed negotiation. Workaround :change PHYTOV[31:24]
from 0x36 to 0x3B.

commit 0a96e9754d6c4a2a31e50ee6c6e36ec13f80bc25 upstream.
PCI and SR-IOV Fixes
- Call pci_save_state after the pci_restore_state completes.
- After calling pci_enable_pcie_error_reporting() and checking the return
value for logging messages from rc, reset rc to 0 to it will not later be
interpreted for error.
- Read PCI config space SR-IOV capability to get the number of VFs supported.
- Check for the PF's supported number of VFs before invoking PCI enable sriov
API call and log error message that user requested number of VFs is beyond
the PF capability if such request is passed in.
- Added check for Physical function with Virtual Functions attached. If so,
first disable all the VFs before proceeding to device reset.
