Testing with h2 and linux has uncovered some bugs in the way the locks are
implemented and privileged instructions.

Note that this will be rebased to make adjustments when the *next_pc removals
land.  See https://lore.kernel.org/qemu-devel/20261008211005.1853542-1-brian.cain@oss.qualcomm.com/

In v2:
- now rebased after *next_pc state removal, hex_tlb_lock() now receives the
packet PC, records that PC before halting the CPU, then exits TB.
- minivm test now preserves sparse test_mmu file in the archive, so
extraction is fast, disk space required is small.  Removed skipBigDataTest
filter and subTest() hack.

v1: https://lore.kernel.org/qemu-devel/20261009192541.4163758-1-brian.cain@oss.qualcomm.com/

Brian Cain (5):
  target/hexagon: check privilege mode for system instructions
  target/hexagon: wake K0 and TLB lock waiters
  target/hexagon: halt on tlblock when the TLB lock is contended
  target/hexagon: set a started thread's enable bit when start retires
  tests/functional/hexagon: add MiniVM, lock tests
