Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

Description:
|
|
Attribute group to describe the magic bits that go into
|
|
perf_event_attr::config[012] for a particular pmu.
|
|
Each attribute of this group defines the 'hardware' bitmask
|
|
we want to export, so that userspace can deal with sane
|
|
name/value pairs.
|
|
|
|
Userspace must be prepared for the possibility that attributes
|
|
define overlapping bit ranges. For example:
|
|
attr1 = 'config:0-23'
|
|
attr2 = 'config:0-7'
|
|
attr3 = 'config:12-35'
|
|
|
|
Example: 'config1:1,6-10,44'
|
|
Defines contents of attribute that occupies bits 1,6-10,44 of
|
|
perf_event_attr::config1.
