Modified Files:
        src/sys/uvm: uvm_bio.c

Log Message:
- ubc_uiomove():  Always use direct access in the UBC_FAULTBUSY case, since
  it works basically the same way as !direct minus temporary mappings, and
  there are no concurrency issues.

- ubc_alloc_direct(): In the PGO_OVERWRITE case blocks are allocated
  beforehand.  Avoid waking or activating pages unless needed.
