#     powerpc/highmem: Change BUG_ON() to WARN_ON()
#     
#     In arch/powerpc/mm/highmem.c, BUG_ON() is called only when
#     CONFIG_DEBUG_HIGHMEM is selected, this means the BUG_ON() is not vital
#     and can be replaced by a a WARN_ON().
#     
#     At the same time, use IS_ENABLED() instead of #ifdef to clean a bit.

WARNING: vmlinux.o(.text+0x2d28): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:early_setup()
The function start_here_multiplatform() references
the function __init early_setup().
This is often because start_here_multiplatform lacks a __init 
annotation or the annotation of early_setup is wrong.

WARNING: vmlinux.o(.text+0x2d5c): 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.
