Hi all,

After merging the arm64 tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/perf/arm_cspmu/arm_cspmu.c: In function 'arm_cspmu_get_cpus':
drivers/perf/arm_cspmu/arm_cspmu.c:1114:29: error: implicit declaration of function 'get_acpi_id_for_cpu' [-Werror=implicit-function-declaration]
 1114 |                             get_acpi_id_for_cpu(cpu)) {
      |                             ^~~~~~~~~~~~~~~~~~~

Caused by commit

  e37dfd65731d ("perf: arm_cspmu: Add support for ARM CoreSight PMU driver")

I have used the arm64 tree from next-20221115 for today.
