   1 /********************************************************************
   2  Flush register windows on sparc.
   3
   4  This function is in a separate file to prevent inlining. The "flushw"
   5  assembler instruction used on sparcv9 flushes all register windows
   6  except the current one, so if it is inlined, the current register
   7  window of the process executing the instruction will not be flushed
   8  correctly.
