1a8382d6ee Added used include of <sys/mutex.h>. The SMP case was broken by 
incompletely converting simplelocks to mutexes (COM_LOCK() is supposed
to hide the SMP locking internals, but it now depends on mutex interfaces
being visible).

fc82a0c37b Clear intr_nesting_level when an interrupt thread has no more 
handlers and wants to exit, so it doesn't panic in exit1()
which malloc()s with M_WAITOK.

4f534409b3 Move the setting of curproc to idleproc up earlier in ap_init(). The 
problem is that a mutex lock, prior to this change, is acquired before
the curproc is set to idleproc, so we mess ourselves up by calling
the mutex lock routine with curproc == NULL.

Moving it up after the aps_ready spin-wait has us hopefully setting it
after idleproc is setup.

Solved by: jake (the allmighty) :-)

ec55088093 Move most of sys/mutex.h into kern/kern_mutex.c, thereby making the mutex 
inline functions non-inlined.  Hide parts of the mutex implementation that
should not be exposed.

Make sure that WITNESS code is not executed during boot until the mutexes
are fully initialized by SI_SUB_MUTEX (the original motivation for this
commit).

b3c27aaaf7 First step towards an MP-safe zone allocator: 
- have zalloc() and zfree() always lock the vm_zone.
 - remove zalloci() and zfreei(), which are now redundant.
