Subject: perf: Bump max number of cpus to 1024
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4d255766d28b1fecec7e00ab4166b2c17bfc37be;p=openwrt%2Fstaging%2Fblogic.git

perf: Bump max number of cpus to 1024

SPARC based systems currently support up to 1024 cpus (e.g. T5-8).
Allow perf to work on those systems.
