2014-06-11bsd-user: add HOST_VARIANT_DIR for various *BSD dependent codeStacey Son2-1/+13
This change adds HOST_VARIANT_DIR so the various BSD OS dependent code can be separated into its own directories rather than using #ifdef's. This may also allow an BSD variant OS to host another BSD variant's executable as a target.

2014-06-11exec: replace ffsl with ctzlNatanael Copa1-1/+1
See commit fbeadf50 (bitops: unify bitops_ffsl with the one in host-utils.h, call it bitops_ctzl) on why ctzl should be used instead of ffsl. This is also needed for musl libc which does not implement ffsl.

2014-06-11vhost: replace ffsl with ctzlNatanael Copa1-4/+2
Avoid using the GNU extesion ffsl which is not implemented in musl libc. The atomic_xchg() means we know that vhost_log_chunk_t will never be larger than the 'long' type, so ctzl() is always sufficient.

2014-06-11util/qemu-openpty: fix build with musl libc by include termios.h as fallbackNatanael Copa1-0/+2
Include termios.h as POSIX fallback when not glibc, bsd or solaris. POSIX says that termios.h should define struct termios and TCAFLUSH. http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/termios.h.html This fixes the following compile errors with musl libc: util/qemu-openpty.c: In function 'qemu_openpty_raw': util/qemu-openpty.c:112:20: error: storage size of 'tty' isn't known struct termios tty; ^ ... util/qemu-openpty.c:128:24: error: 'TCSAFLUSH' undeclared (first use in this function) tcsetattr(*aslave, TCSAFLUSH, &tty); ^ Signed-off-by: Natanael Copa <ncopa@alpinelinux.org> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2014-06-11bsd-user/mmap.c: Don't try to override g_malloc/g_freePeter Maydell1-60/+0
Trying to override the implementations of g_malloc and g_free is a really bad idea -- it means statically linked builds fail to link (because of the multiple definitions provided by this file and by glib), and non-statically linked builds segfault as soon as they try to do anything more complicated than printing the usage message. Remove these overridden versions and just use the glib ones. This is sufficient that bsd-user can run basic x86-64 binaries on OpenBSD again; FreeBSD and NetBSD seem to have further issues.

2014-06-11util/hbitmap.c: Use ctpopl rather than reimplementing a local equivalentPeter Maydell1-7/+2
The function popcountl() in hbitmap.c is effectively a reimplementation of what host-utils.h provides as ctpopl(). Use ctpopl() directly; this fixes a failure to compile on NetBSD (whose strings.h erroneously exposes a system popcountl() which clashes with this one).

2014-06-10migration: Plug memory leak in migrate-set-cache-size commandChen Gang2-1/+1
We call g_free() after cache_fini() in migration_end(), but we don't call it after cache_fini() in xbzrle_cache_resize(), leaking the memory. cache_init() and cache_fini() are a pair. Since cache_init() allocates the cache, let cache_fini() free it. This plugs the leak.
