From b34497d1844ac89269eb2c6faea0ceec7757a9c3 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Thu, 24 Apr 2014 18:00:10 +1000 Subject: [PATCH] powerpc/powernv: Remove fields in PHB diag-data dump For some fields (e.g. LEM, MMIO, DMA) in PHB diag-data dump, it's meaningless to print them if they have non-zero value in the corresponding mask registers because we always have non-zero values in the mask registers. The patch only prints those fieds if we have non-zero values in the primary registers (e.g. LEM, MMIO, DMA status) so that we can save couple of lines. The patch also removes unnecessary spare line before "brdgCtl:" and two leading spaces as prefix in each line as Ben suggested.
