5cf8cf4146 Fix FREEZE/THAW compat_ioctl regression
Commit 8e961870bb removed the FREEZE/THAW
handling in xfs_compat_ioctl but never added any compat handler back, so
now any freeze/thaw request from a 32-bit binary ond 64-bit userspace
will fail.

As these ioctls are 32/64-bit compatible two simple COMPATIBLE_IOCTL
entries in fs/compat_ioctl.c will do the job.

It's this instruction:

Which corresponds to a dereference of va->purge_list.next:

It seems that we should use "safe" list traversal here, as the element
is freed inside the loop. Please verify that this is the right fix.

5170836679 Fix recursive lock in free_uid()/free_user_ns()
free_uid() and free_user_ns() are corecursive when CONFIG_USER_SCHED=n,
but free_user_ns() is called from free_uid() by way of uid_hash_remove(),
which requires uidhash_lock to be held.  free_user_ns() then calls
free_uid() to complete the destruction.

Fix this by deferring the destruction of the user_namespace.

3ecdb9acf3 USB: musb: be careful with 64K+ transfer lengths, host side
Feeding 32-bit length cast down to 'u16' to min() to calculate the FIFO
count in musb_host_tx() risks sending a short packet prematurely for
transfer sizes over 64 KB.

Similarly, although data transfer size shouldn't exceed 65535 bytes for
the control endpoint, making musb_h_ep0_continue() more robust WRT URBs
with possibly oversized buffer will not hurt either...

51d9f3e100 USB: musb: fix data toggle saving with shared FIFO
For some strange reason the host side musb_giveback() decides
that it's always got an IN transfer when the hardware endpoint
is using a shared FIFO.  This causes musb_save_toggle() to read
the toggle state from the RXCSR register instead of TXCSR, and
may also cause unneeded reloading of RX endpoint registers.

dc61d238b8 USB: musb: host endpoint_disable() oops fixes
The musb_h_disable() routine can oops in some cases:

 - It's not safe to read hep->hcpriv outside musb->lock,
   since it gets changed on completion IRQ paths.

 - The list iterators aren't safe to use in that way;
   just remove the first element while !list_empty(),
   so deletions on other code paths can't make trouble.

We need two "scrub the list" loops because only one branch
should touch hardware and advance the schedule.

a2fd814e6a USB: musb: fix urb_dequeue() method
The urb_dequeue() method forgets to unlink 'struct musb_qh' from the
control or bulk schedules when the URB being cancelled is the only
one queued to its endpoint.  That will cause musb_advance_schedule()
to block once it reaches 'struct musb_qh' with now empty URB list, so
URBs queued for other endpoints after the one being dequeued will not
be served.

Fix by unlinking the QH from the list except when it's already being
handled (typically by musb_giveback).  Since a QH with an empty URB
list is now supposed to be freed, do that.  And remove a now-useless
check from musb_advance_schedule().

34f32c9701 usb: musb: make Davinci *work* in mainline
Now that the musb build fixes for DaVinci got merged (RC3?), kick in
the other bits needed to get it finally *working* in mainline:

 - Use clk_enable()/clk_disable() ... the "always enable USB clocks"
   code this originally relied on has since been removed.

 - Initialize the USB device only after the relevant I2C GPIOs are
   available, so the host side can properly enable VBUS.

 - Tweak init sequencing to cope with mainline's relatively late init
   of the I2C system bus for power switches, transceivers, and so on.

Sanity tested on DM6664 EVM for host and peripheral modes; that system
won't boot with CONFIG_PM enabled, so OTG can't yet be tested.  Also
verified on OMAP3.

(Unrelated:  correct the MODULE_PARM_DESC spelling of musb_debug.)

67f5a4ba97 USB: usb_get_string should check the descriptor type
This patch (as1218) fixes a problem with a radio-control joystick used
in the "walkera 4#3" helicopter.  This device responds to the initial
Get-String-Descriptor request for string 0 (which is really the list
of supported languages) by sending its config descriptor!  The
usb_get_string() routine needs to check whether it got the right
type of descriptor.

Oddly enough, this sort of check is already present in
usb_get_descriptor().  The patch changes the error code from -EPROTO
to -ENODATA, because -EPROTO shows up in so many other contexts to
indicate a hardware failure rather than a firmware error.

29a46bf6f4 usb: gadget: obex: select correct ep descriptors
We where selecting wrong ep descriptors causing
some troubles while sending files over obex interface.

The problem was a typo while usb_find_endpoint() was being
called for HS endpoints.

9aa09d2f8f USB: EHCI: slow down ITD reuse
Currently ITDs are immediately recycled whenever their URB completes.
However, EHCI hardware can sometimes remember some ITD state.  This
means that when the ITD is reused before end-of-frame it may sometimes
cause the hardware to reference bogus state.

This patch defers reusing such ITDs by moving them into a new ehci member
cached_itd_list. ITDs resting in cached_itd_list are moved back into their
stream's free_list once scan_periodic() detects that the active frame has
elapsed.

This makes the snd_usb_us122l driver (in kernel since .28) work right
when it's hooked up through EHCI.

acfa5110b8 Staging: w35und: fix usb_control_msg() error handling in wb35_probe()
If successful, the usb_control_msg() function returns the number of
bytes transferred. Fix up wb35_probe() to only bail out if the function returns
a negative number. Also, fix up ieee80211_alloc_hw() error code to ENOMEM;
otherwise GCC complains that err might be undefined (and is right about that).

096c55d1de Staging: rtl8187se: Fix oops and memory poison caused by builtin ieee80211.
when modprobe and removing rtl8187se ( just for testing, i do not have
that card , and oops and a memory poison error happens on the builtin
ieee80211 of that driver.  I dont know if they will port it to the
current ieeee80221 instead of the builtin ones, but just in case i
attach a proposed fix for that problem.

- Change for loop on ieee80211_crypto_deinit for list_for_each_safe to
  remove items. Is there an spinlock needed here?
- Call ieee80211_crypto_deinit after exiting all registerd crypto protocols.

69e09c983e Staging: rtl8187se: fix Kconfig dependencies
rtl8187se uses wireless extensions so it needs to depend on
WIRELESS_EXT (or select it).

rtl8187se uses fields in struct net_device that are only present
if CONFIG_COMPAT_NET_DEV_OPS=y, so it needs to depend on
that symbol also.

0bfbce18b9 nl80211: Avoid AP mode BUG_ON hang with invalid lock assert
"cfg80211: add assert_cfg80211_lock() to ensure proper protection"
added assert_cfg80211_lock() calls into various places. At least
one of them, nl80211_send_wiphy(), should not have been there. That
triggers the BUG_ON in assert_cfg80211_lock() and pretty much kills
the kernel whenever someone runs hostapd.. Remove that call and make
assert_cfg80211_lock() use WARN_ON instead of BUG_ON to be a bit more
friendly to users.
