category: feature
bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I8XR3G
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=318c4985911245508f7e0bab5265e208a38b5f18



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

Some attrs and is_visible implementations are rather far away from one
another which makes the whole thing hard to interpret.

There are only two attribute groups which have both .attrs and
.is_visible, group_default and group_caps_lbr. Move them together.

No functional changes.

Intel-SIG: commit 318c49859112 perf/x86/intel: Reorganize attrs and is_visible
Backport LBR branch counter support to kernel v6.6.
