This should remedy the kernel panics due to an assertion failure in
vm_page.c that various people have reported.
Regards,
Alan

Modified files:
sys/vm vm_page.c
Log:
Revision 1.52 of vm/uma_core.c has led to UMA's obj_alloc() being
called without Giant; and obj_alloc() in turn calls vm_page_alloc()
without Giant. This causes an assertion failure in vm_page_alloc().
Fortunately, obj_alloc() is now MPSAFE. So, we need only clean up
some assertions.
- Weaken the assertion in vm_page_lookup() to require Giant only
if the vm_object isn't locked.
- Remove an assertion from vm_page_alloc() that duplicates a check
performed in vm_page_lookup().
