Modified Files:
        src/sys/arch/m68k/m68k: pmap_motorola.c

Log Message:
in pmap_enter_ptpage(), if we are allowed to fail then fail rather than
waiting for memory to be available.  when we are mapping an anon or uobj page
then we will be holding the lock for that page owner, and sleeping to wait
for memory with a page owner lock held is illegal because the pagedaemon
can wait for that lock, which will lead to deadlock.  fixes PR 56932.
