While at Connect I had a go at reproducing a problem that Ard had
reported to me about guest debug not working. I managed to replicate
it and uncovered a few other nits in the process. While upgrading to a
tip-of-tree gdb to get around:


works we certainly can be better at handling the DBGBVR bits in QEMU.
That fixed the additional BQL assertion and target_el assertion
failures are harder to trigger (you need to debug your debug while
debugging debug). However I've included the obvious fixes for that as

Alex Bennée (4):
  target/arm64: properly handle DBGVR RESS bits
  target/arm64: hold BQL when calling do_interrupt()
  target/arm64: kvm debug set target_el when passing exception to guest
  tests/guest-debug: fix scoping of failcount
