Subject: perf arm_spe: Correct memory level for remote access
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=cb300e3515057fb555983ce47e8acc86a5c69c3c;p=users%2Fhch%2Fmisc.git

perf arm_spe: Correct memory level for remote access

For remote accesses, the data source packet does not contain information
about the memory level. To avoid misinformation, set the memory level to
NA (Not Available).
