Paul Burton 00bf1c691d MIPS: tlbex: Avoid placing software PTE bits in Entry* PFN fields ... Commit 748e787eb6 ("MIPS: Optimize TLB refill for RI/XI configurations.") stopped explicitly clearing the bits used by software in PTEs by making use of a rotate instruction that rotates them into the fill bits of the Entry{Lo,Hi} register. This can only work if there are actually enough fill bits in the register to cover the software maintained bits, otherwise we end up writing those bits into the upper bits of the PFN or PFNX field of the Entry{Lo,Hi} register. Fix this by detecting the number of fill bits present in the Entry{Lo,Hi} registers & explicitly clearing the software bits where necessary.
