duplicate tlb entries

duplicate tlb entries

[Marco]

Hello,

Could anyone tell me if the following dump_tlb_all() is valid?  I see a 
few duplicate tlb entries, which I'm under the impression is not a good 
thing.  Unfortunately, I haven't been able to figure it out from my 
investigating.  I'm using a Mips32/r4000-style TLB setup with 2.6.16.18.

I did the dump below during a squashfs error I was experiencing.

Also please note I commented out
       if ((entryhi & 0xf0000000) != 0x80000000
            && (entryhi & 0xff) == asid) {
which normally suppresses some of the output so every tlb entry would be 
dumped.


Heres dump_tlb_all() output slightly modified and sorted on va for 
readability.
