This patch introduces a new macro "__NR_CPUS__" to perf's embedded
clang compiler, which represent the available CPU counters in this
system. BPF program can use this macro to create a map with same
number of system CPUs. For exmaple:
struct bpf_map_def SEC("maps") pmu_map = {

You have done different types of changes in this patch. Please break
them up so that each patch will be doing only one type of change.
Also your subject is not correct.

Some atomic operations now have _relaxed/acquire/release variants, this
patch then adds some trivial tests for two purpose:
1. test the behavior of these new operations in single-CPU
environment.
2. make their code generated before we actually use them somewhere,

Folks, the LKP robot reported an issue with Paolo's recent bug fix

that KERNEL_PGD_PTRS is not the correct constant to use when copying

For primary plane initialization failure cases, ipu_plane_init() may return
a pointer encoded by ERR_PTR(). So, we should bailout instead of use that
pointer blindly.

Since we are using ipu_plane_init() to add one primary plane for each
IPU CRTC, it's unnecessary to create the safe one by using the helper
create_primary_plane().
Furthermore, the safe one is attached to crtc->primary, which actually
carries a framebuffer(crtc->primary->fb) created by the fbdev
