Subject: perf: arm_v6/7_pmu: Drop non-DT probe support
X-Git-Tag: v6.11-rc1~217^2~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=12f051c987dc91d3bf7c4dbb740321f8b24070b4;p=thirdparty%2Fkernel%2Flinux.git

perf: arm_v6/7_pmu: Drop non-DT probe support

There are no non-DT based PMU users for v6 or v7, so drop the custom
non-DT probe table. Unfortunately XScale still needs non-DT probing.

Note that this drops support for arm1156 PMU, but there are no arm1156
based systems supported in the kernel.
