#     modpost: return error if module is missing ns imports and MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS=n
#     
#     Currently when CONFIG_MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS=n, modpost
#     only warns when a module is missing namespace imports. Under this
#     configuration, such a module cannot be loaded into the kernel anyway, as
#     the module loader would reject it. We might as well return a build
#     error when a module is missing namespace imports under
#     CONFIG_MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS=n, so that the build
#     warning does not go ignored/unnoticed.

WARNING: modpost: vmlinux.o(.text+0x31dc): 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: modpost: 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.
