sparc64: Do not clobber %g2 in xcall_fetch_glob_regs().
[ Upstream commit a5a737e090e25981e99d69f01400e3a80356581c ]
%g2 is meant to hold the CPUID number throughout this routine, since
at the very beginning, and at the very end, we use %g2 to calculate
indexes into per-cpu arrays.
However we erroneously clobber it in order to hold the %cwp register
value mid-stream.
Fix this code to use %g3 for the %cwp read and related calulcations
instead.
