Subject: [PATCH] Quieten cache information at boot
Date: Sun, 14 Oct 2007 14:33:17 -0500	[thread overview]
Message-ID: <20071014193317.GC26693@kryten> (raw)


After 6 years the ppc64 kernel still thinks its important to tell me my
cache line size is 0x80 bytes. I think most people who care know that by
now. The rest probably cant even understand the hex output.

Since we might have misconfigured firmware or cpus that have a linesize
that isnt 128 bytes, I still print it out for those cases. If people
would prefer to remove it completely, lets do it.

Also for lpar remove the htab_address printout since its not used.
