Subject: This patch pulls out the auxiliary vector struct from individual ISA
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e2c7618e508c6e5c0cbbd091eabb336f3e259465;p=gem5.git

This patch pulls out the auxiliary vector struct from individual ISA
LiveProcesses to the base LiveProcess definition so anyone can use them.
