svn commit: r195371 - projects/mips/sys/mips/mips

[Warner Losh]

New Revision: 195371
URL: http://svn.freebsd.org/changeset/base/195371

Log:
  Now that we define atomic_{load,store}_64 inline in atomic.h, we don't
  need to define them here for the !N64 case.
  
  We now define atomic_readandclear_64 in atomic.h, so no need to repeat
  it here.
