H A D | pci-ioda.c | caa58f80 Mon Sep 05 23:17:18 CDT 2016 Gavin Shan <gwshan@linux.vnet.ibm.com> powerpc/powernv: Fix corrupted PE allocation bitmap on releasing PE
In pnv_ioda_free_pe(), the PE object (including the associated PE number) is cleared before resetting the corresponding bit in the PE allocation bitmap. It means PE#0 is always released to the bitmap wrongly.
This fixes above issue by caching the PE number before the PE object is cleared.
