Subject: [PARISC] Make local cache flushes take a void *
X-Git-Tag: v2.6.16-rc1~428^2~19
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1b2425e3c79984975a1a3e6fa84512f23d96da9f;p=linux-2.6

[PARISC] Make local cache flushes take a void *

Make flush_data_cache_local, flush_instruction_cache_local and
flush_tlb_all_local take a void * so they don't have to be cast
when using on_each_cpu().  This becomes a problem when on_each_cpu
is a macro (as it is in current -mm).

Also move the prototype of flush_tlb_all_local into tlbflush.h and
remove its declaration from .c files.
