Subject: sh: perf: Set up perf_max_events.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=51c6c9bb34fcd112d4ab8b8f5c1d1b6a10a00e71;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

sh: perf: Set up perf_max_events.

Presently this is uninitialized in the architecture code, so it's
artificlally capped to the default initialization value. Set it up at
registration time.
