Nathan Froyd bbfa8f72e9 target-mips: add microMIPS exception handler support
Unlike MIPS16, microMIPS lets you choose the ISA mode for your exception
handlers.  The ISA mode is selectable via a user-writable CP0.Config3
flag.

Paul Brook d4c430a80f Large page TLB flush
QEMU uses a fixed page size for the CPU TLB.  If the guest uses large
pages then we effectively split these into multiple smaller pages, and
populate the corresponding TLB entries on demand.

When the guest invalidates the TLB by virtual address we must invalidate
all entries covered by the large page.  However the address used to
invalidate the entry may not be present in the QEMU TLB, so we do not
know which regions to clear.

Implementing a full vaiable size TLB is hard and slow, so just keep a
simple address/mask pair to record which addresses may have been mapped by
large pages.  If the guest invalidates this region then flush the
whole TLB.

Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b72.
