[POWERPC] iSeries: Make iseries_reg_save private to iSeries
Now that we have the alpaca, the reg_save_ptr is no longer needed in the paca. Eradicate all global uses of it and make it static in the iSeries lpardata.c Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
