66ce3e08c5 system/core Replace cutils/log.h with android/log.h
Should use android/log.h instead of cutils/log.h as a good example
to all others.  Adjust header order to comply with Android Coding
standards.

Use the wakeup count interface for requesting suspend, instead of
autosleep, to allow userspace to collect stats on suspend/resume
activity.

a26b4caf4c autosuspend_inited flag set even if initialization fails
Prevents possible SIGSEGV on second autosuspend_enable attempt when
first intialization attempt fails.  autosuspend_inited should only
be set once autosuspend_ops has been assigned.

Consider the first call to autosuspend_enable().
autosuspend_init() sets its inited flag to true, and attempts to
set autosuspend_ops.  If all the other autosuspend_*_init() attempts
fail, autosuspend_init() returns -1, which autosuspend_enable()
will return as a failure.  A second call to autosuspend_enable()
will check autosuspend_init() and see that autosuspend has already
been initialized.  It will attempt to access autosuspend_ops, which
were not set in the first initialization attempt, causing a SIGSEGV.
