Subject: mem: Ensure deferred snoops are cache-line aligned
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=912b20d02a4ec12b076e675ff150e3f1e89febaa;p=gem5.git

mem: Ensure deferred snoops are cache-line aligned

partial cache line, and not cache-line aligned, all due to how we copy
the packet.
