Subject: [SPARC64]: Don't clobber alt-global %g4 on window fixups.
X-Git-Tag: v2.6.17-rc1~1184^2~208

[SPARC64]: Don't clobber alt-global %g4 on window fixups.

If we are returning back to kernel mode, %g4 could be live
(for example, in the case where we window spill in the etrap
code).  So do not change it's value if going back to kernel.
