Subject: [parisc-linux] [PATCH 17/23] [PARISC] Match show_cache_info with reality
Date: Sun, 25 Jun 2006 19:34:45 -0400	[thread overview]
Message-ID: <11512784931379-git-send-email-kyle@parisc-linux.org> (raw)
In-Reply-To: <20060625233123.GC2837@athena.road.mcmartin.ca>

show_cache_info and struct pdc_cache_cf were out of sync with
published documentation. Fix the reporting of cache associativity
and update the pdc_cache_cf bitfields to match documentation.
