H A Dprom_init_check.shdiff 450e7dd4001f22f796e22422dd1d2cbd5bda21fc Fri Apr 26 11:23:28 CDT 2019 Christophe Leroy <christophe.leroy@c-s.fr> powerpc/prom_init: don't use string functions from lib/

When KASAN is active, the string functions in lib/ are doing the
KASAN checks. This is too early for prom_init.

This patch implements dedicated string functions for prom_init,
which will be compiled in with KASAN disabled.

Size of prom_init before the patch:
text data bss dec hex filename
12060 488 6960 19508 4c34 arch/powerpc/kernel/prom_init.o

Size of prom_init after the patch:
text data bss dec hex filename
12460 488 6960 19908 4dc4 arch/powerpc/kernel/prom_init.o

This increases the size of prom_init a bit, but as prom_init is
in __init section, it is freed after boot anyway.
