Re: Problems with allyesconfig kernel build

This was first noted with the -mm tree, but has now migrated into 
Linus'
tree.  An allyesconfig build dies in the link stage like this:

/usr/bin/ld: arch/powerpc/kernel/head_64.o(.text+0x80c8): sibling call 
optimization to `.text.init.refok' does not allow automatic multiple 
TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls, or 
make `.text.init.refok' extern
/usr/bin/ld: arch/powerpc/kernel/head_64.o(.text+0x8160): sibling call 
optimization to `.text.init.refok' does not allow automatic multiple 
TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls, or 
make `.text.init.refok' extern
/usr/bin/ld: arch/powerpc/kernel/head_64.o(.text+0x81c4): sibling call 
optimization to `.text.init.refok' does not allow automatic multiple 
TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls, or 
make `.text.init.refok' extern
/usr/bin/ld: final link failed: Bad value

I just tried, and it works fine for me.

Intuiting the obvious, I changed all the _INIT_STATIC and _INIT_GLOBAL
uses in head_64.S back to _STATIC and _GLOBAL (which just moves the 
code
from .text.init.refok to .text).  Now the linker segfaults instead.  
:-)

Tried that, too, and no segfault, everything happy.

$ ld --version
GNU ld (GNU Binutils for Debian) 2.18

I'm using CVS HEAD of binutils.  Could you try that, with the same
GCC version you are currently using?  Just to narrow things down...
