[PATCH v2] Schedule removal of arch/ppc

[PATCH v2] Schedule removal of arch/ppc

[Josh Boyer]

The arch/ppc tree has been in a semi-nebulous "bug fix only" state for a
few kernel releases now.  The patch below officially declares this as of
the 2.6.22 kernel release and schedules arch/ppc for removal in June of
2008.

June 2008 is a long time away to let this linger. Why not say by End of the
year 2007?  That should give folks essentially two more 2.6 releases.

Regards,

Tom

A year seemed like the appropriate amount of time for an arch removal.
And Segher had made a suggestion that it could be officially killed
during the PowerPC BOF at OLS 2008 for fun.  But honestly, it doesn't
matter to me.  As others have said, things can always be resurrected
from old tags if needs be.

Essentially, I'm trying to be sneaky and get Paul to declare it dead
officially.  When it actually dies, I don't care ;)

Please don't; us 4xx folks aren't yet ready.  Active support for
Xilinx Virtex in arch/ppc only right now.  I want to move over to
arch/powerpc; but end of year is rather aggressive.

cheers,

Selfishly, that's why I listed it as June 2008 to begin with.  We've got
base 440 support in arch/powerpc now, but it needs more work.  And I
just started 405 this morning.

However, I definitely want some date present when arch/ppc will go away.
Otherwise it will languish on indefinitely, more so than it already has.

Given that we started this process (or at least made the decision to
start it) in July 2005, June 2008 sounds quite reasonable as an end
date.

Is that a signed-off-by?  Hurray!
