Subject: Re: [PATCH v2 11/30] perf pmu-events: Add e_machine to struct pmu_events_map

> The CPUID strings in the pmu-events mapfile.csv files have an
> architecture specific format, such as "GenuineIntel-6-55-[56789ABCDEF]"
> on x86 or a MIDR value like "0x00000000410fd0c0" on arm64. When perf is
> built with JEVENTS_ARCH=all the tables of every architecture are
> present and map_for_cpu() compared the host's CPUID against all of
> them, even though only the host architecture's tables can match.
>
> Record the ELF machine of each architecture's CPUIDs in struct
> pmu_events_map, EM_NONE for the test and common tables, and have
> map_for_cpu() only consider tables for the host's ELF machine. The 32
> and 64-bit variants of x86 and PowerPC share tables.
