[PATCH] powerpc: remove second definition of STACK_FRAME_OVERHEAD

Stephen Rothwell sfr at canb.auug.org.au
Fri Nov 19 12:06:17 EST 2010 

Since STACK_FRAME_OVERHEAD is defined in asm/ptrace.h and that
is ASSEMBER safe, we can just include that instead of going via
asm-offsets.h.

This was prompted by another change that caused the multiple definitions
to produce a warning.  That warning has already been fixe, but this seems
the correct thing to do anyway.

I have build tested this for all the (top level) powerpc defconfigs.
