 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
