All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0x5b7f13): Section mismatch in reference from the function tick_nohz_full_setup() to the function .init.text:alloc_bootmem_cpumask_var()
The function tick_nohz_full_setup() references
the function __init alloc_bootmem_cpumask_var().
This is often because tick_nohz_full_setup lacks a __init
annotation or the annotation of alloc_bootmem_cpumask_var is wrong.
