mainline inclusion
from mainline-v5.15-rc1
commit 5806099a
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I63VF5
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=5806099a2e2ab36fa7a7705faaf3d7296b701e67

--------------------------------------------------------------------------

Calling pmu_is_uncore() for fake PMUs does not work, as it checks sysfs
for the PMU details (which won't exist).

Check .is_uncore field instead, which makes sense anyway.
