Hi Scott,
You are right. The TLB handlers for 8xx in arch/powerpc branch set the
PAGE_ACCESSED flag unconditionally too. And the
include/asm-powerpc/pgtable-ppc32.h file still includes the comment that this
is the bug. So, probably the corresponding patch for powerpc branch will be
usefull. Does anybody use swap with some of the 8xx-based boards supported in
powerpc branch ?
Regards, Yuri
