Violators will be prosecuted for from ; Tue, 3 Jul 2018 18:05:14 +0100 From: Mike Rapoport Subject: [PATCH] mm/memblock: replace u64 with phys_addr_t where appropriate Date: Tue, 3 Jul 2018 20:05:06 +0300 Message-Id: <1530637506-1256-1-git-send-email-rppt@linux.vnet.ibm.com> Sender: owner-linux-mm@kvack.org List-ID: To: Andrew Morton Cc: linux-mm , lkml , Mike Rapoport , Michal Hocko , Matthew Wilcox Most functions in memblock already use phys_addr_t to represent a physical address with __memblock_free_late() being an exception. This patch replaces u64 with phys_addr_t in __memblock_free_late() and switches several format strings from %llx to %pa to avoid casting from phys_addr_t to u64.
