Subject: malta 4kc and tlb-r4k.c

Message-ID: <3C474909.4DF82E72@mvista.com> (raw)

I needed to add a BARRIER between :

set_entryhi(KSEG0+idx*0x2000);  and
 tlb_write_indexed();

in  local_flush_tlb_range()  (tlb-r4k.c), otherwise I get a bootup
failure:

Kernel panic: Caught Machine Check exception - probably caused by
multiple matching entries in the TLB.

Malta 5kc didn't have this problem.

Also,  the call
set_entryhi(KSEG0);
doesn't seem necessary.
