From 2de4823dc0424923a6d6070a7378a7bf6ee67556 Mon Sep 17 00:00:00 2001 From: Thomas Chou Date: Tue, 27 Oct 2015 09:02:17 +0800 Subject: nios2: change virt_to_phys to use physaddr_mask in global data As virt_to_phys() is used a lot in DMA transfer, change it to use physaddr_mask in global data. This will save an "if" statement and get a little faster.
