Subject: [PATCH] m68k: mcfmmu: remove stale part of comment about steal_context
Date: Thu, 18 Jun 2020 11:17:27 +0300	[thread overview]
Message-ID: <20200618081727.4741-1-rppt@kernel.org> (raw)

From: Mike Rapoport <rppt@linux.ibm.com>

The comment about steal_context() came from powerpc and a part of it
addresses differences between powerpc variants that are not really
relevant to m68k.

Remove that part of the comment.

Hi,

I've found this by pure chance while grepping for pgalloc.h
It's been there since 2011, but I don't think it's a stable material, so I
didn't cc them.

 /*
  * Steal a context from a task that has one at the moment.
- * This is only used on 8xx and 4xx and we presently assume that
- * they don't do SMP.  If they do then thicfpgalloc.hs will have to check
- * whether the MM we steal is in use.
- * We also assume that this is only used on systems that don't
- * use an MMU hash table - this is true for 8xx and 4xx.
  * This isn't an LRU system, it just frees up each context in
  * turn (sort-of pseudo-random replacement :).  This would be the
  * place to implement an LRU scheme if anyone was motivated to do it.
