ppc64 kernel config changes heads up

[Peter Robinson]

Hi All,

If you don't care about powerpc you can stop reading :-)

If you do.... I went to do what I thought was a basic fix up to the
kernel builds on POWER to get rid of the last bits of the ppc32
legacy, on my list for some time, and it has become more of a slightly
epic slash and burn!

The resulting output kernel configs are for all intents and purpose
unchanged but the git diff is some what epic.

The top level of the changes are:

Core changes that apply too all kernels (ppc64/ppc64p7/ppc64le) reside
in config-powerpc64-generic

config-powerpc64 -> legacy platforms that are older than POWER7 and
their dependencies (here lies the ghosts of PowerPC G5 and friends).

config-powerpc64le and config-powerpc64p7 contain anything specific to
POWER7 and newer that might affect older platforms, or LE/BE specific
to p7 and later

I've removed anything that pertains to PPC32 and Cell processors (the
later were all disabled now anyway) but if the kernel docs were wrong
and they do by chance work on some other 64 bit platform that still
works do let me know.

So the only thing of real note is the ppc64p7 and ppc64le configs no
longer have any old IDE configs enabled or any of the legacy Apple
bits pulled in, I don't believe that should cause any pain what so
ever, I only bring this up because it's the only thing of note on
diffs of before/after resulting config diffs.

So ultimately please test kernel builds going forward. There's a
scratch build here [1] until we get an official one to test. There's
no perf packages, that appears broeken... even on vanilla pre commit
:)

For those that are morbidly interested in the diff (and don't have the
Fedora kernel package check out) you can see that here [2].

Ultimately the large git commit looks quite scary but the actual
change to the 3 configs are minimal and I believe this should make
things cleaner moving forward :-)

I look forward to the testing feedback including any further suggested
cleanups to the new configs, oh and please test :-)
