[Qemu-devel] [PATCH 00/10] translate-all.c thread-safety

[Paolo Bonzini <pbonzini@redhat.com>]

Hi, this is my attempt at 1) extracting upstreamable parts out of Fred's
MTTCG, and 2) documenting what's going on in user-mode MTTCG 3) fix
one bug in the process.  I couldn't find any other locking problem
from reading the code.

The final two patches are not really upstreamable because they
add some still unnecessary locks to system emulation, but I included
them to show what's going on.  With this locking logic I do not need
tb_lock to be recursive anymore.

KONRAD Frederic (4):
  cpus: protect work list with work_mutex
  cpus: remove tcg_halt_cond global variable.
  replace spinlock by QemuMutex.
  tcg: protect TBContext with tb_lock.

Paolo Bonzini (8):
  exec-all: remove non-TCG stuff from exec-all.h header.
  cpu-exec: elide more icount code if CONFIG_USER_ONLY
  tcg: code_bitmap is not used by user-mode emulation
  tcg: comment on which functions have to be called with mmap_lock held
  tcg: add memory barriers in page_find_alloc accesses
  exec: make mmap_lock/mmap_unlock globally available
  cpu-exec: fix lock hierarchy for user-mode emulation
  tcg: comment on which functions have to be called with tb_lock held
