      usb: hub: take hub->hdev reference when processing from eventlist · c605f3cd
      Joe Lawrence authored 
      During surprise device hotplug removal tests, it was observed that
hub_events may try to call usb_lock_device on a device that has already
been freed. Protect the usb_device by taking out a reference (under the
hub_event_lock) when hub_events pulls it off the list, returning the
reference after hub_events is finished using it.

      uas: Disable uas on ASM1051 devices · a9c54caa
      Hans de Goede authored 
      There are a large numbers of issues with ASM1051 devices in uas mode:

1) They do not support REPORT SUPPORTED OPERATION CODES

2) They use out of spec 8 byte status iu-s when they have no sense data,
   switching to normal 16 byte status iu-s when they do have sense data.

3) They hang / crash when combined with some disks, e.g. a Crucial M500 ssd.

4) They hang / crash when stressed (through e.g. sg_reset --bus) with disks
   with which then normally do work (once 1 & 2 are worked around).

Where as in BOT mode they appear to work fine, so the best way forward with
these devices is to just blacklist them for uas usage.

Unfortunately this is easier said then done. as older versions of the ASM1053
(which works fine) use the same usb-id as the ASM1051.

When connected over USB-3 the 2 can be told apart by the number of streams
they support. So this patch adds some less then pretty code to disable uas for
the ASM1051. When connected over USB-2, simply disable uas alltogether for
devices with the shared usb-id.

      This VID:PID is used for some Direct IP devices behaving
identical to the already supported 0F3D:68AA devices.

      USB: sierra: avoid CDC class functions on "68A3" devices · 049255f5
      Bjørn Mork authored 
      Sierra Wireless Direct IP devices using the 68A3 product ID
can be configured for modes including a CDC ECM class function.
The known example uses interface numbers 12 and 13 for the ECM
control and data interfaces respectively, consistent with CDC
MBIM function interface numbering on other Sierra devices.

It seems cleaner to restrict this driver to the ff/ff/ff
vendor specific interfaces rather than increasing the already
long interface number blacklist.  This should be more future
proof if Sierra adds more class functions using interface
numbers not yet in the blacklist.

      Add back some PIDs that were mistakingly remove when reverting commit
73228a05 ("USB: option,zte_ev: move most ZTE CDMA devices to
zte_ev"), which apparently did more than its commit message claimed in
that it not only moved some PIDs from option to zte_ev but also added
some new ones.

      Pull Xtensa updates from Chris Zankel:
 "Xtensa improvements for 3.17:
   - support highmem on cores with aliasing data cache.  Enable highmem
     on kc705 by default
   - simplify addition of new core variants (no need to modify Kconfig /
     Makefiles)
   - improve robustness of unaligned access handler and its interaction
     with window overflow/underflow exception handlers
   - deprecate atomic and spill registers syscalls
   - clean up Kconfig: remove orphan MATH_EMULATION, sort 'select'
     statements
   - wire up renameat2 syscall.

  Various fixes:
   - fix address checks in dma_{alloc,free}_coherent (runtime BUG)
   - fix access to THREAD_RA/THREAD_SP/THREAD_DS (debug build breakage)
   - fix TLBTEMP_BASE_2 region handling in fast_second_level_miss
     (runtime unrecoverable exception)
   - fix a6 and a7 handling in fast_syscall_xtensa (runtime userspace
     register clobbering)
   - fix kernel/user jump out of fast_unaligned (potential runtime
     unrecoverabl exception)
   - replace termios IOCTL code definitions with constants (userspace
     build breakage)"

Bisect points to commit 649671c9 ("unicore32: Use get_signal()

This code never even compiled.  Reverting the patch does not work, since
previously used functions no longer exist, so try to fix it up.  Compile
tested only.
