[PATCH v3 0/9] bsd-user mmap fixes

[Warner Losh]

This series synchronizes mmap.c with the bsd-user fork. This is a mix of old bug
fixes pulled in from linux-user, as well as some newer fixes to adress bugs
found in check-tcg and recent FreeBSD developments. There are also a couple of
style commits. Updated to migrate debugging to qemu_log.

v3: reimplement the logging with qemu_log
    redo MAP_EXCL based on review feedback
    update fd == -1 MAP_ANON fix with description of what's going on

v2: do the cherry-picks from linux-user in qemu-style.

Guy Yur (1):
  bsd-user/mmap.c: Don't mmap fd == -1 independently from MAP_ANON flag

Kyle Evans (1):
  bsd-user/mmap.c: Implement MAP_EXCL, required by jemalloc in head

Mikaël Urankar (2):
  bsd-user/mmap.c: Always zero MAP_ANONYMOUS memory in mmap_frag()
  bsd-user/mmap.c: check pread's return value to fix warnings with
    _FORTIFY_SOURCE

Warner Losh (5):
  bsd-user/mmap.c: MAP_ symbols are defined, so no need for ifdefs
  bsd-user/mmap.c: mmap return ENOMEM on overflow
  bsd-user/mmap.c: mmap prefer MAP_ANON for BSD
  bsd-user/mmap.c: Convert to qemu_log logging for mmap debugging
  bsd-user/mmap.c: assert that target_mprotect cannot fail
