#     powerpc/powernv: no need to check return value of debugfs_create functions
#     
#     When calling debugfs functions, there is no need to ever check the
#     return value.  The function can work or not, but the code logic should
#     never do something different based on this.

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.

WARNING: vmlinux.o(.text+0x33c8): 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.
