      watchdog: kempld: revert to full dependency · ed4a9eca
      Arnd Bergmann authored 
      The kempld watchdog driver requires the respective MFD driver:

drivers/watchdog/built-in.o: In function `kempld_wdt_probe':
kempld_wdt.c:(.text+0x5c78): undefined reference to `kempld_get_mutex'
kempld_wdt.c:(.text+0x5c84): undefined reference to `kempld_read8'
kempld_wdt.c:(.text+0x5c8e): undefined reference to `kempld_release_mutex'
kempld_wdt.c:(.text+0x5d1c): undefined reference to `kempld_read8'
kempld_wdt.c:(.text+0x5d2c): undefined reference to `kempld_write8'

This adds the Kconfig dependency back.

      watchdog: bcm2835: add CONFIG_OF dependency · 2672b7e0
      Arnd Bergmann authored 
      Without CONFIG_OF, the driver fails to link:

drivers/watchdog/built-in.o: In function `bcm2835_power_off':
bcm2835_wdt.c:(.text+0x1946): undefined reference to `of_find_device_by_node'

This adds a new dependency, to allow the COMPILE_TEST check to succeed.

      watchdog: sp805: add back AMBA dependency · 3eafee95
      Arnd Bergmann authored 
      The driver fails to link if ARM_AMBA is disabled:

drivers/watchdog/sp805_wdt.o: In function `sp805_wdt_driver_init':
sp805_wdt.c:(.init.text+0x4): undefined reference to `amba_driver_register'

It seems that the COMPILE_TEST was added in the wrong place, as there
is no architecture dependency, but a bus dependency. This moves
the dependency accordingly.

      watchdog: menf21bmc: add I2C dependency · 6fb303a8
      Arnd Bergmann authored 
      This driver fails to link when CONFIG_I2C is disabled or a loadable module while
the watchdog is built-in:

drivers/watchdog/built-in.o: In function `menf21bmc_wdt_shutdown':
menf21bmc_wdt.c:(.text+0x9b44): undefined reference to `i2c_smbus_write_word_data'
menf21bmc_wdt.c:(.text+0x9b44): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `i2c_smbus_write_word_data'

This adds a Kconfig dependency for it, to enforce a valid configuration.

      watchdog: geode: restore hard CS5535_MFGPT dependency · 0369fdf2
      Arnd Bergmann authored 
      Wtihout CONFIG_CS5535_MFGPT, the driver does not link right:

drivers/watchdog/built-in.o: In function `geodewdt_probe':
geodewdt.c:(.init.text+0xca3): undefined reference to `cs5535_mfgpt_alloc_timer'

geodewdt.c:(.init.text+0xcef): undefined reference to `cs5535_mfgpt_toggle_event'

This adds back the dependency on this base driver.

      watchdog: wm831x watchdog really needs mfd · d0e32fba
      Arnd Bergmann authored 
      The wm831x watchdog driver can now be built without the wm831x mfd
driver, which results in a link error:

(.text+0x1a95c): undefined reference to `wm831x_set_bits'
(.text+0x1a95c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `wm831x_set_bits'
(.text+0x1a968): undefined reference to `wm831x_reg_lock'
(.text+0x1a968): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `wm831x_reg_lock'
(.text+0x1a9dc): undefined reference to `wm831x_reg_unlock'
(.text+0x1a9dc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `wm831x_reg_unlock'

This adds back the dependency that was removed. We can still build test
this driver on all architectures by enabling the MFD driver for it first.

      Pull IPMI updates from Corey Minyard:
 "This is a few small fixes to the main IPMI driver, make some things
  const, fix typos, etc.

  The last patch came in about a week ago, but IMHO it's best to go in
  now. It is not for the main driver, it's for the bt-bmc driver, which
  runs on the managment controller side, not on the host side, so the
  scope is limited and the change is necessary"

      Merge branch 'idr-4.11' of git://git.infradead.org/users/willy/linux-dax · cf393195
      Linus Torvalds authored 
      Pull IDR rewrite from Matthew Wilcox:
 "The most significant part of the following is the patch to rewrite the
  IDR & IDA to be clients of the radix tree. But there's much more,
  including an enhancement of the IDA to be significantly more space
  efficient, an IDR & IDA test suite, some improvements to the IDR API
  (and driver changes to take advantage of those improvements), several
  improvements to the radix tree test suite and RCU annotations.

  The IDR & IDA rewrite had a good spin in linux-next and Andrew's tree
  for most of the last cycle. Coupled with the IDR test suite, I feel
  pretty confident that any remaining bugs are quite hard to hit. 0-day
  did a great job of watching my git tree and pointing out problems; as
  it hit them, I added new test-cases to be sure not to be caught the
  same way twice"

Willy goes on to expand a bit on the IDR rewrite rationale:
 "The radix tree and the IDR use very similar data structures.

  Merging the two codebases lets us share the memory allocation pools,
  and results in a net deletion of 500 lines of code. It also opens up
  the possibility of exposing more of the features of the radix tree to
  users of the IDR (and I have some interesting patches along those
  lines waiting for 4.12)

  It also shrinks the size of the 'struct idr' from 40 bytes to 24 which
  will shrink a fair few data structures that embed an IDR"
