Subject: [PATCH 0/3] Add some missing cache infomation
Date: Thu, 08 Jun 2017 22:57:00 -0000	[thread overview]
Message-ID: <20170608225728.26779-1-rth@twiddle.net> (raw)

I was looking to use _SC_LEVEL1_ICACHE_LINESIZE in QEMU,
and notice that some of our common hosts are missing this
information.

For my purposes, a guess at the linesize is good enough,
and I can't imagine that returning the linesize used for
flushing the cache could be incorrect.
