svn commit: r222840 - head/sys/sparc64/sparc64

New Revision: 222840
URL: http://svn.freebsd.org/changeset/base/222840

Log:
  - For the case when tl1_align(_trap) is used to call rsf_fatal via
    RSF_FATAL we need to switch to alternate globals for KSTACK_CHECK just
    like tl1_data_excptn(_trap) does. This is more or less cosmetic because
    in case RSF_FATAL is called we're already heading south.
  - Correct an END().
  - Read the window state from the correct register for a CATR().
