Add setup_initial_init_mm() helper, then use it
to cleanup the text, data and brk setup code.
v3:
- resend all and fix x86 warning
- make helper declaration in mm.h, implemention in init-mm.c, suggested
by Mike
- collect ACKs
v2:
- change argument from "char *" to "void *" setup_initial_init_mm()
suggested by Geert Uytterhoeven
- use NULL instead of (void *)0 on h8300 and m68k
Kefeng Wang (15):
mm: add setup_initial_init_mm() helper
arc: convert to setup_initial_init_mm()
arm: convert to setup_initial_init_mm()
arm64: convert to setup_initial_init_mm()
csky: convert to setup_initial_init_mm()
h8300: convert to setup_initial_init_mm()
m68k: convert to setup_initial_init_mm()
nds32: convert to setup_initial_init_mm()
nios2: convert to setup_initial_init_mm()
openrisc: convert to setup_initial_init_mm()
powerpc: convert to setup_initial_init_mm()
riscv: convert to setup_initial_init_mm()
s390: convert to setup_initial_init_mm()
sh: convert to setup_initial_init_mm()
x86: convert to setup_initial_init_mm()
