[Qemu-devel] [PATCH for-2.4 0/8] memory: enable unlocked PIO/MMIO in KVM

[Paolo Bonzini <pbonzini@redhat.com>]

And here we are...  These are the changes required to make the BQL
optional for memory access, and use that support in KVM.  For now,
only one device model is changed to do unlocked accesses.

Please review!

Jan Kiszka (4):
  memory: Add global-locking property to memory regions
  memory: Provide address_space_rw_unlocked
  kvm: First step to push iothread lock out of inner run loop
  kvm: Switch to unlocked PIO

Paolo Bonzini (4):
  exec: move rcu_read_lock/unlock to address_space_translate callers
  exec: mark unassigned_io_ops as unlocked
  acpi: mark PMTIMER as unlocked
  kvm: Switch to unlocked MMIO
