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. Fixes: 1e9167726c41 ("powerpc/powernv: Use PE instead of number during setup and release" Cc: stable@vger.kernel.org # v4.7+ Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
