#     merge_config.sh: ignore unwanted grep errors
#     
#     The merge_config.sh script verifies that all the config options have
#     their expected value in the resulting file and prints any issues as
#     warnings.  These checks aren't intended to be treated as errors given
#     the current implementation.  However, since "set -e" was added, if the
#     grep command to look for a config option does not find it the script
#     will then abort prematurely.
#     
#     Handle the case where the grep exit status is non-zero by setting
#     ACTUAL_VAL to an empty string to restore previous functionality.
#     
#     Fixes: cdfca821571d ("merge_config.sh: Check error codes from make")

WARNING: vmlinux.o(.text+0x2fd0): 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.
