[PATCH 0/4] Relocate module code from init.h to module.h

[PATCH 0/4] Relocate module code from init.h to module.h

[Paul Gortmaker]

What started as a removal of no longer required include <linux/init.h>
due to the earlier __cpuinit and __devinit removal led to the observation
that some module specfic support was living in init.h itself, thus
preventing the full removal from introducing compile regressions.

This series of commits includes the final relocation of the modular
init code from <init.h> to <module.h> -- we do this because modular
users will always be users of init functionality, but users of init
functionality are not necessarily always modules.  Once done, the
trivial one line removals can be finalized at any time, a bit at a
time, through maintainer trees etc.

In order to do that, a couple of final things that this will uncover
are fixed up here -- things that weren't easily categorized into any
of the other previous series leading up to this final one.  The
previous groupings of commits that get us to this final series are:

1: [PATCH 00/11] Delete new __cpuinit users and then delete stubs
   https://lkml.kernel.org/r/1430174880-27958-1-git-send-email-paul.gortmaker at windriver.com

2: [PATCH 00/11] Fix implicit includes of <module.h> that will break.                                                                                                                    
   https://lkml.kernel.org/r/1430444867-22342-1-git-send-email-paul.gortmaker at windriver.com>

3: [PATCH 00/15] Replace module_init with device_initcall in non modules                                                                                                                 
   https://lkml.kernel.org/r/1432860493-23831-1-git-send-email-paul.gortmaker at windriver.com

4: [PATCH 00/11] Replace module_init with an alternate initcall in non modules                                                                                                           
   https://lkml.kernel.org/r/1433120052-18281-1-git-send-email-paul.gortmaker at windriver.com

5: [PATCH 0/7] Introduce builtin_driver and use it for non-modular code
   https://lkml.kernel.org/r/1431287385-1526-1-git-send-email-paul.gortmaker at windriver.com>

This group of six is factored out from what was a previously larger series[1]
so that there is a common theme and lower patch count to ease review.  Setting
aside the trivial one line include <linux/init.h> removals for later also
greatly reduces the series size and makes all six parts more manageable.

Paul.

[PATCH 2/4] arm: fix implicit #include <linux/init.h> in entry asm.

[Paul Gortmaker]

They use the "_INIT" macro and friends, and hence need to
source this header file, vs. relying on getting it implicitly.
