Merge tag 'init_task-20180117' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull init_task initializer cleanups from David Howells:
"It doesn't seem useful to have the init_task in a header file rather
than in a normal source file. We could consolidate init_task handling
instead and expand out various macros.
Here's a series of patches that consolidate init_task handling:
(1) Make THREAD_SIZE available to vmlinux.lds for cris, hexagon and
openrisc.
(2) Alter the INIT_TASK_DATA linker script macro to set
init_thread_union and init_stack rather than defining these in C.
Insert init_task and init_thread_into into the init_stack area in
the linker script as appropriate to the configuration, with
different section markers so that they end up correctly ordered.
We can then get merge ia64's init_task.c into the main one.
We then have a bunch of single-use INIT_*() macros that seem only
to be macros because they used to be used per-arch. We can then
expand these in place of the user and get rid of a few lines and
a lot of backslashes.
(3) Expand INIT_TASK() in place.
(4) Expand in place various small INIT_*() macros that are defined
conditionally. Expand them and surround them by #if[n]def/#endif
in the .c file as it takes fewer lines.
(5) Expand INIT_SIGNALS() and INIT_SIGHAND() in place.
(6) Expand INIT_STRUCT_PID in place.
These macros can then be discarded"
