If mfc0 $12 follows store and the mfc0 is last instruction of a page and fetching the next instruction causes TLB miss, the result of the mfc0 might wrongly contain EXL bit.
Hmm, a TLB miss in fetching from KSEG0?!
ERT-TX49H2-027, ERT-TX49H3-012, ERT-TX49HL3-006, ERT-TX49H4-008 Workaround: mask EXL bit of the result or place a nop before mfc0.
Is this workaround really needed?
