      soc: ti: wkup_m3_ipc: Fix race condition with rproc_boot · 03729cfa
      Dave Gerlach authored 
      Any user of wkup_m3_ipc calls wkup_m3_ipc_get to get a handle and this
checks the value of the static variable m3_ipc_state to see if the
wkup_m3 is ready. Currently this is populated during probe before
rproc_boot has been called, meaning there is a window of time that
wkup_m3_ipc_get can return a valid handle but the wkup_m3 itself is not
ready, leading to invalid IPC calls to the wkup_m3 and system
instability.

To avoid this, move the population of the m3_ipc_state variable until
after rproc_boot has succeeded to guarantee a valid and usable handle
is always returned.

      ARM: dts: beagle-x15-common: Model 5V0 regulator · e17e7c49
      Kishon Vijay Abraham I authored 
      On am57xx-beagle-x15, 5V0 is connected to P16, P17, P18 and P19
connectors. On am57xx-evm, 5V0 regulator is used to get 3V6 regulator
which is connected to the COMQ port. Model 5V0 regulator here in order
for it to be used in am57xx-evm to model 3V6 regulator.

      ARM: dts: am571x-idk: Fix gpios property to have the correct gpio number · 0c4eb2a6
      Kishon Vijay Abraham I authored 
      commit d23f3839 ("ARM: dts: DRA7: Add pcie1 dt node for
EP mode") while adding the dt node for EP mode for DRA7 platform,
added rc node for am571x-idk and populated gpios property with
"gpio3 23". However the GPIO_PCIE_SWRST line is actually connected
to "gpio5 18". Fix it here. (The patch adding "gpio3 23" was tested
with another am57x board in EP mode which doesn't rely on reset from
host).

      Kishon Vijay Abraham I authored 
      PERST# line in the PCIE connector is driven by the host mode and not
EP mode. The gpios property here is used for driving the PERST# line.
Remove gpios property from all endpoint device tree nodes.

 "I didn't get a batch in this weekend, so here's what we queued up last
  week and today.

   - A couple of defconfigs add back debugfs -- it used to be implicitly
     enabled through CONFIG_TRACING, but 0e4a459f ("tracing:
     Remove unnecessary DEBUG_FS dependency") removed that.

   - The rest are mostly minor fixlets of the usual kind; some DT

      Pull rdma fixes from Doug Ledford:
 "A small collection of -rc fixes. Mostly. One API addition, but that's
  because we wanted to use it in a fix. There's also a bug fix that is
  going to render the 5.5 kernel's soft-RoCE driver incompatible with
  all soft-RoCE versions prior, but it's required to actually implement
  the protocol according to the RoCE spec and required in order for the
  soft-RoCE driver to be able to successfully work with actual RoCE
  hardware.

  Summary:

   - Update Steve Wise info

   - Fix for soft-RoCE crc calculations (will break back compatibility,
     but only with the soft-RoCE driver, which has had this bug since it
     was introduced and it is an on-the-wire bug, but will make
     soft-RoCE fully compatible with real RoCE hardware)

   - cma init fixup

   - counters oops fix

   - fix for mlx4 init/teardown sequence

   - fix for mkx5 steering rules

   - introduce a cleanup API, which isn't a fix, but we want to use it
     in the next fix

   - fix for mlx5 memory management that uses API in previous patch"

      Linus Torvalds authored 
      Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski:
 "This small series replaces all in-kernel calls to the
  userspace-focused ksys_mount() and ksys_dup() with calls to
  kernel-centric functions:

  For each replacement of ksys_mount() with do_mount(), one needs to
  verify that the first and third parameter (char *dev_name, char *type)
  are strings allocated in kernelspace and that the fifth parameter
  (void *data) is either NULL or refers to a full page (only occurence
  in init/do_mounts.c::do_mount_root()). The second and fourth
  parameters (char *dir_name, unsigned long flags) are passed by
  ksys_mount() to do_mount() unchanged, and therefore do not require
  particular care.

  Moreover, instead of pretending to be userspace, the opening of
  /dev/console as stdin/stdout/stderr can be implemented using in-kernel
  functions as well. Thereby, ksys_dup() can be removed for good"

[ This doesn't get rid of the special "kernel init runs with KERNEL_DS"
  case, but it at least removes _some_ of the users of "treat kernel
  pointers as user pointers for our magical init sequence".

  One day we'll hopefully be rid of it all, and can initialize our
  init_thread addr_limit to USER_DS.    - Linus ]
