#     
#     Pull KVM fixes from Paolo Bonzini:
#      "ARM and x86 bugfixes of all kinds.
#     
#       The most visible one is that migrating a nested hypervisor has always
#       been busted on Broadwell and newer processors, and that has finally
#       been fixed"

WARNING: vmlinux.o(.text+0x31e4): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init()
The function __boot_from_prom() references
the function __init prom_init().
This is often because __boot_from_prom lacks a __init 
annotation or the annotation of prom_init is wrong.

The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init
