[Qemu-devel] [PATCH qom v4 7/7] cpus: Change exec_init() arg to cpu, not env

[Peter Crosthwaite]

The callers (most of them in target-foo/cpu.c) to this function all
have the cpu pointer handy. Just pass it to avoid an ENV_GET_CPU() from
core code (in exec.c).

changed since v3:
inline cpu->env_ptr to get rid of C99 declaration (eduardo review).
changed since v1:
Add () to function in commit message.
Rebase on Bharata's Error ** patch
