-Subject: powerpc/pci: Fix unmapping of IO space on 64-bit
-From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
-References: 439491
-
-A typo/thinko made us pass the wrong argument to __flush_hash_table_range
-when unplugging bridges, thus not flushing all the translations for
-the IO space on unplug.
-
-This causes the hypervisor to refuse unplugging slots.
