#     powerpc/64: remove support for kernel-mode syscalls
#     
#     There is support for the kernel to execute the 'sc 0' instruction and
#     make a system call to itself. This is a relic that is unused in the
#     tree, therefore untested. It's also highly questionable for modules to
#     be doing this.

WARNING: vmlinux.o(.text+0x2bc8): 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.
