From 191c5cf1ffc8acf61cd2d2407052ced1a1116130 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Thu, 25 Aug 2011 13:06:57 -0500 Subject: [PATCH] tty/powerpc: fix build break with ehv_bytechan.c on allyesconfig The ePAPR hypervisor byte channel driver is supposed to work on all ePAPR-compliant embedded PowerPC systems, but it had a reference to the MSR_GS bit, which is available only on Book-E systems. Also fix a couple integer-to-pointer typecast problems.
