Hi guys,

I read from the Qemu internal documentation this:
    ``When MMU mappings change, only the chaining of the basic 
    blocks is reset (i.e. a basic block can no longer jump directly 
    to another one).''

But when I read the code, I find that tlb_flush() doesn't reset the
chaining between TBs. Is that the intended behaviour?? Won't that
cause problems on guest context switch??

If two people love each other, there can be no happy end to it.
