[PATCH] powerpc/tm: Print 64-bits MSR

From: Breno Leitao <leitao@debian.org>
Date: 2018-08-07 00:32:55
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

On a kernel TM Bad thing program exception, the MSR is not being properly
displayed, since it dumps a 32-bits value. MSR is a 64 bits register for
all platforms that have HTM enabled.

This patch dumps the MSR value as 64-bits instead of 32 bits.
