Message

Kefeng Wang June 8, 2021, 8:34 a.m. UTC

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
