Re: [PATCH] powerpc: merge include/asm/cputable.h

Arnd,

I not sure I understand what the introduction of the enum's gets us.

This is an updated version of my old patch that creates a more  
optimized
version of cpu_has_feature(). This version actually combines
asm-ppc/cputable.h and asm-ppc64/cputable.h, which turned out to be
a lot more work than only the 64 bit version.

The 64 bit parts a relatively straightforward port of my earlier work
which I tested in a number of configurations. The 32 bit parts are
not tested at all, all I did was compiling the ppc defconfig with  
this.

I think it is best if I hand the patch over to Kumar and Becky for
further testing and cleaning up the remaining bits in the new
file, as they appear to have invested some thought in it already.
This version still has a number of #ifdef __powerpc64__ that should
probably go away in the process.

The patch also relies on having the ASM_CONST() macro in ppc_asm.h,
as proposed by Kumar Gala, so it won't work on the current git
head without that change.
