Modified Files:
        src/sys/fs/tmpfs: tmpfs_vnops.c
        src/sys/uvm: uvm_aobj.c uvm_bio.c uvm_object.c uvm_pager.h uvm_vnode.c

Log Message:
PR kern/32166: pgo_get protocol is ambiguous
Also problems with tmpfs+nfs noted by hannken@.

Don't pass PGO_ALLPAGES to pgo_get, and ignore PGO_DONTCARE in the
!PGO_LOCKED case.  In uao_get() have uvm_pagealloc() take care of page
zeroing and release busy pages on error.
