Pull module_init replacement part one from Paul Gortmaker:
"Replace module_init with equivalent device_initcall in non modules.
This series of commits converts non-modular code that is using the
module_init() call to hook itself into the system to instead use
device_initcall().
The conversion is a runtime no-op, since module_init actually becomes
__initcall in the non-modular case, and that in turn gets mapped onto
device_initcall. A couple files show a larger negative diffstat,
representing ones that had a module_exit function that we remove here
vs previously relying on the linker to dispose of it.
We make this conversion now, so that we can relocate module_init from
init.h into module.h in the future.
The files changed here are just limited to those that would otherwise
have to add module.h to obviously non-modular code, in order to avoid
a compile fail, as testing has shown"

The zonelist locking and the oom_sem are two overlapping locks that are
used to serialize global OOM killing against different things.
The historical zonelist locking serializes OOM kills from allocations with
overlapping zonelists against each other to prevent killing more tasks
than necessary in the same memory domain. Only when neither tasklists nor
zonelists from two concurrent OOM kills overlap (tasks in separate memcgs
bound to separate nodes) are OOM kills allowed to execute in parallel.
The younger oom_sem is a read-write lock to serialize OOM killing against
the PM code trying to disable the OOM killer altogether.
However, the OOM killer is a fairly cold error path, there is really no
reason to optimize for highly performant and concurrent OOM kills. And
the oom_sem is just flat-out redundant.
Replace both locking schemes with a single global mutex serializing OOM
kills regardless of context.

- a big set of cleanups to the aged sysfs interface from Johan

* NXP LPC18xx (currently LPC1850)
* NetLogic XLP

* Axis ETRAXFS
* Zynq Ultrascale+ (subdriver)
- ACPI:

* merge some dependent I2C changes exploiting this.
* support the ARM X-Gene GPIO standby driver.

The metag_da TTY driver can't get built as a module at the moment, but
it still uses module_init() and module_exit(). Those macros are moving
to module.h which isn't included by metag_da.c, which will result in the
following build warnings (remarkably no build errors) and an apparent
failure to boot as the TTY driver won't be loaded.
drivers/tty/metag_da.c:660: warning: data definition has no type or storage class

drivers/tty/metag_da.c:670 : warning: passing argument 4 of ‘chancall’ discards qualifiers from pointer target type
Instead of just adding the module.h include, now would be a good time to
remove the use of these macros, replacing the module_init with
device_initcall, and removing the exit function altogether since it
isn't needed. If module support is added later the code can always be
resurrected.
