Thanks, but this fails an allmodconfig build for me:


arch/arm64/kernel/kaslr.c: In function ‘kaslr_early_init’:
arch/arm64/kernel/kaslr.c:127:6: error: implicit declaration of function ‘__early_cpu_has_rndr’; did you mean ‘__early_pfn_to_nid’? [-Werror=implicit-function-declaration]
  if (__early_cpu_has_rndr()) {
      ^~~~~~~~~~~~~~~~~~~~
      __early_pfn_to_nid
cc1: some warnings being treated as errors


(no gcc, we didn't mean that!)
