[PATCH] powernv: Load correct TOC pointer while waking up from winkle.

2016-08-05 Thread Mahesh J Salgaonkar
From: Mahesh Salgaonkar The function pnv_restore_hyp_resource() loads the TOC into r2 from the invalid PACA pointer before fixing r13 value. This do not affect POWER ISA 3.0 but it does have an impact on POWER ISA 2.07 or less leading CPU to get stuck forever. login: [ 471.830433] Proce
