#     
#        - fix a crash when shutting down a KVM PR guest (our original style
#          of KVM which doesn't use hypervisor mode)
#     
#        - fix for the recently added 32-bit KASAN_VMALLOC support
#

WARNING: vmlinux.o(.text+0x2fc8): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
