#     kbuild: add --hash-style= and --build-id unconditionally
#     
#     As commit 1e0221374e30 ("mips: vdso: drop unnecessary cc-ldoption")
#     explained, these flags are supported by the minimal required version
#     of binutils. They are supported by ld.lld too.

WARNING: vmlinux.o(.text+0x3204): 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+0x33d0): 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.
