[POWERPC] Stop the TOC overflowing for large builds
We were using -mno-minimal-toc on everything in arch/powerpc/kernel, which means that all the functions in there were putting all their TOC entries in the top-level TOC, and it was overflowing on an allyesconfig build. For various reasons, prom_init.c does need -mno-minimal-toc, but the other .c files in there can use sub-TOCs quite happily. This change is sufficient for now to stop the TOC overflowing; other directories under arch/powerpc also use -mno-minimal-toc and could also be changed later if necessary. Lmbench runs with and without this patch showed no significant speed differences. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
