ab16bdd834 staging: lustre: llog: fix wrong offset in llog_process_thread()
- llh_cat_idx may become bigger than llog bitmap size in
  llog_cat_set_first_idx() function
- it is wrong to use previous cur_offset as new buffer offset,
  new offset should be calculated from value returned by
  llog_next_block().
- optimize llog_skip_over() to find llog entry offset by index
  for llog with fixed-size records.

80dd4c42cc staging/lustre/ptlrpc: track unreplied requests
The request xid was used to make sure the ost object timestamps
being updated by the out of order setattr/punch/write requests
properly. However, this mechanism is broken by the multiple rcvd
slot feature, where we deferred the xid assignment from request
packing to request sending.

This patch moved back the xid assignment to request packing, and
the manner of finding lowest unreplied xid is changed from scan
sending & delay list to scan a unreplied requests list.

This patch also skipped packing the known replied XID in connect
and disconnect request, so that we can make sure the known replied
XID is increased only on both server & client side.

6fde3789a2 staging: vc04_services: clarify firmware dependency
The raspberrypi-firmware driver may be built as a loadable module,
which causes a link-time failure if the vc04_services driver is
built-in during compile-testing:

drivers/staging/vc04_services/vchiq.o: In function `vchiq_probe':
vchiq_connected.c:(.text.vchiq_probe+0x2c): undefined reference to `rpi_firmware_get'
drivers/staging/vc04_services/vchiq.o: In function `vchiq_platform_init':
vchiq_connected.c:(.text.vchiq_platform_init+0x1f0): undefined reference to `rpi_firmware_property'

This extends the dependency list to ensure the firmware is either
reachable, or completely disabled in case of compile-testing.

b826d73b30 staging: vc04_services: remove duplicate mutex_lock_interruptible
The driver tries to redefine mutex_lock_interruptible as an open-coded
mutex_lock_killable, but that definition clashes with the normal
mutex_lock_interruptible definition when CONFIG_DEBUG_LOCK_ALLOC
is set:

staging/vc04_services/interface/vchiq_arm/vchiq_killable.h:67:0: error: "mutex_lock_interruptible" redefined [-Werror]
 #define mutex_lock_interruptible mutex_lock_interruptible_killable
include/linux/mutex.h:161:0: note: this is the location of the previous definition

This simply removes the private implementation and uses the
normal mutex_lock_killable directly.

We could do the same for the down_interruptible_killable here, but
it's better to just remove the semaphores entirely from the driver,
which also takes care of that.

735bb39ca3 staging: wilc1000: simplify vif[i]->ndev accesses
With gcc-7, I got a new warning for this driver:

wilc1000/linux_wlan.c: In function 'wilc_netdev_cleanup':
wilc1000/linux_wlan.c:1224:15: error: 'vif[1]' may be used uninitialized in this function [-Werror=maybe-uninitialized]
wilc1000/linux_wlan.c:1224:15: error: 'vif[0]' may be used uninitialized in this function [-Werror=maybe-uninitialized]

A closer look at the function reveals that it's more complex than
it needs to be, given that based on how the device is created
we always get

	netdev_priv(vif->ndev) == vif

Based on this assumption, I found a few other places in the same file
that can be simplified. That code appears to be a relic from times
when the assumption above was not valid.

 * mpu3050
   - Remove duplicate initializer for the module owner.
   - Add missing i2c dependency.
   - Inform the i2c mux core how it is used - step one in implifying device
   tree bindings.
 * st-sensors
   - Get rid of large number of uninformative defines in favour of putting the
   constants where they are relevant. It is clear what they are from where
   they are used.
 * tsl2583
   - Fix unused function warning when CONFIG_PM disabled and remove the
   ifdefs in favour of __maybe_unused.
   - Refactor taos_chip_on  to only read relevant registers.
   - Make sure calibscale and integration time are being set.
   - Verify chip is in ready to be used before calibration.
   - Remove some repeated checks for chip status (it's protected by a mutex
   so can't change until it's released)
   - Change current state storage from a tristate enum to a boolean seeing as
   only two values are actually used now.
   - Drop a redundant write to the control regiser in taos_probe (it's a noop)
   - Drop the FSF mailing address.
   - Clean up logging to not use hard coded function names (use __func__
   instead).
   - Cleanup up variable and function name prefixes.
   - Alignment of #define fixes.
   - Fix comparison between signed and unsigned integer warnings.
   - Add some newlines in favour of readability.
   - Combine the two sysfs ABI docs that somehow ended up in different places.
   - Fix multiline comment syntax.
   - Move a code block to inside an else statement as it makes more sense there.
   - Change tsl2583_als_calibrate to return 0 rather than a value nothing
   reads.
   - Drop some pointless brackets
   - Don't assume 32bit unsigned int.
   - Change to a per device instance lux table.
   - Add missing tsl2583 to the list of supported devices in the intro comments.
   - Improve commment on clearing of interrupts.
   - Drop some uninformative comments.
   - Drop a memset call that doesn't do anything useful any more.
   - Don't initialize some return variables that are always set.
   - Add Brian Masney as a module author after all these changes.

  so can't change until it's released)
  - Change current state storage from a tristate enum to a boolean seeing as
  only two values are actually used now.
  - Drop a redundant write to the control regiser in taos_probe (it's a noop)
  - Drop the FSF mailing address.
  - Clean up logging to not use hard coded function names (use __func__
  instead).
  - Cleanup up variable and function name prefixes.
  - Alignment of #define fixes.
  - Fix comparison between signed and unsigned integer warnings.
  - Add some newlines in favour of readability.
  - Combine the two sysfs ABI docs that somehow ended up in different places.
  - Fix multiline comment syntax.
  - Move a code block to inside an else statement as it makes more sense there.
  - Change tsl2583_als_calibrate to return 0 rather than a value nothing
  reads.
  - Drop some pointless brackets
  - Don't assume 32bit unsigned int.
  - Change to a per device instance lux table.
  - Add missing tsl2583 to the list of supported devices in the intro comments.
  - Improve commment on clearing of interrupts.
  - Drop some uninformative comments.
  - Drop a memset call that doesn't do anything useful any more.
  - Don't initialize some return variables that are always set.
  - Add Brian Masney as a module author after all these changes.

e3007002f1 staging: comedi: ni_mio_common: remove variable 'dl' in ni_ai_insn_read()
In `ni_ai_insn_read()`, local variable `dl` is declared as `unsigned
long`, but `unsigned int` will do.  Get rid of it and use local variable
`d` instead.  (That used to be `unsigned short`, but has been `unsigned
int` since kernel version 3.18.)

857a661020 staging: comedi: ni_mio_common: fix E series ni_ai_insn_read() data
Commit 0557344e21 ("staging: comedi: ni_mio_common: fix local var for
32-bit read") changed the type of local variable `d` from `unsigned
short` to `unsigned int` to fix a bug introduced in
commit 9c340ac934 ("staging: comedi: ni_stc.h: add read/write
callbacks to struct ni_private") when reading AI data for NI PCI-6110
and PCI-6111 cards.  Unfortunately, other parts of the function rely on
the variable being `unsigned short` when an offset value in local
variable `signbits` is added to `d` before writing the value to the
`data` array:

			d += signbits;
		  	data[n] = d;

The `signbits` variable will be non-zero in bipolar mode, and is used to
convert the hardware's 2's complement, 16-bit numbers to Comedi's
straight binary sample format (with 0 representing the most negative
voltage).  This breaks because `d` is now 32 bits wide instead of 16
bits wide, so after the addition of `signbits`, `data[n]` ends up being
set to values above 65536 for negative voltages.  This affects all
supported "E series" cards except PCI-6143 (and PXI-6143). Fix it by
ANDing the value written to the `data[n]` with the mask 0xffff.

For NI M Series cards, the Comedi `insn_read` handler for the AI
subdevice is broken due to ANDing the value read from the AI FIFO data
register with an incorrect mask.  The incorrect mask clears all but the
most significant bit of the sample data.  It should preserve all the
sample data bits.  Correct it.

After following a discussion about the used integer types Dan Carpenter
pointed out that 'int' types should be used over the current change to
's16'. The reason for this is to have an upper bound instead of overflowing
the 's16' so we could still remove devices.

7cb15d0448 staging: lustre: mdc: manage number of modify RPCs in flight
This patch is the main client part of a new feature that supports
multiple modify metadata RPCs in parallel. Its goal is to improve
metadata operations performance of a single client, while maintening
the consistency of MDT reply reconstruction and MDT recovery
mechanisms.

It allows to manage the number of modify RPCs in flight within
the client obd structure and to assign a virtual index (the tag) to
each modify RPC to help server side cleaning of reply data.

The mdc component uses this feature to send multiple modify RPCs
in parallel.

0ffaa9c8eb staging: lustre: hsm: Use file lease to implement migration
Implement non-blocking migration based on exclusive open instead of
group lock. Implemented exclusive close operation to atomically put
a lease, swap two layouts and close a file. This allows race-free
migrations.

Make the caller responsible for retrying on failure (EBUSY, EAGAIN)
in non-blocking mode.

In blocking mode, allow applications to trigger layout swaps using a
grouplock they already own, to prevent race conditions between the
actual data copy and the layout swap. Updated lfs accordingly. File
leases are also taken in blocking mode, so that lfs migrate can issue
a warning if an application attempts to open a file that is being
migrated and gets blocked.

Timestamps (atime/mtime) are set from userland, after the layout swap
is performed, to prevent conflicts with the grouplock.

lli_trunc_sem is taken/released in the vvp_io layer, under the DLM
lock. This re-ordering fixes the original issue between truncate and
migrate.
