David Gibson 77058e1adc powerpc: Fix address masking bug in hpte_need_flush() ... Commit f71dc176aa 'Make hpte_need_flush() correctly mask for multiple page sizes' introduced bug, which is triggered when a kernel with a 64k base page size is run on a system whose hardware does not 64k hash PTEs. In this case, we emulate 64k pages with multiple 4k hash PTEs, however in hpte_need_flush() we incorrectly only mask the hardware page size from the address, instead of the logical page size. This causes things to go wrong when we later attempt to iterate through the hardware subpages of the logical page. This patch corrects the error. It has been tested on pSeries bare metal by Michael Neuling. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>		15 years ago
