Subject: Blackfin: include system/processor info in dump messages
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9ba3c24f10c948dadac2ca91ed714dfbcedd61ca;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Blackfin: include system/processor info in dump messages

People often copy & paste crash messages without surrounding context, so
include common useful information like system/processor stats in the crash
summary.  This should smooth over the report/test cycle a bit more.
