From 84c5e23edecd7013ceaed8460deed5c33842cb8d Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Mon, 14 Jun 2021 20:27:01 +0800 Subject: [PATCH] arm64: mm: Pass original fault address to handle_mm_fault() Currently, the lower bits of fault address is cleared before it's passed to handle_mm_fault(). It's unnecessary since generic code does same thing since the commit 1a29d85eb0f19 ("mm: use vmf->address instead of of vmf->virtual_address"). This passes the original fault address to handle_mm_fault() in case the generic code needs to know the exact fault address.
