From 51303113e32fd92d327b3c441c45e235642fa69c Mon Sep 17 00:00:00 2001 From: Breno Leitao Date: Tue, 7 Aug 2018 10:35:00 -0300 Subject: powerpc/tm: Print 64-bits MSR On a kernel TM Bad thing program exception, the Machine State Register (MSR) is not being properly displayed. The exception code dumps a 32-bits value but MSR is a 64 bits register for all platforms that have HTM enabled. This patch dumps the MSR value as a 64-bits value instead of 32 bits. In order to do so, the 'reason' variable could not be used, since it trimmed MSR to 32-bits (int).
