Subject: [SPARC64]: Give move verbose show_mem() output just like i386.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5be4a963675d3270fab7f55e8c4a2e56afd408f6;p=linux-beck.git

[SPARC64]: Give move verbose show_mem() output just like i386.

We now report everything i386 does except for highmem which
doesn't apply.
