The sparse tool complains as follow:
arch/powerpc/kernel/btext.c:48:5: warning:
symbol 'boot_text_mapped' was not declared. Should it be static?
This symbol is not used outside of btext.c, so this commit make
it static.

Are you sure the initialisation to 0 can be removed ? Usually initialisation to 0 is not needed
because not initialised variables go in the BSS section which is zeroed at startup. But here the
variable is flagged with __force_data so it is not going in the BSS section.
