The section mismatch analysis checks if there are illegal
references from one section to another section.

During linktime or runtime, some sections are dropped;
any use of code/data previously in these sections would
most likely result in an oops.

__init, __devinit etc. (see full list in include/linux/init.h)
In the code, functions and variables are annotated with
__init, __devinit, etc. (see the full list in include/linux/init.h),
which results in the code/data being placed in specific sections.

The section mismatch analysis is always performed after a full
kernel build, and enabling this option causes the following
additional steps to occur:
- Add the option -fno-inline-functions-called-once to gcc commands.
When inlining a function annotated with __init in a non-init
function, we would lose the section information and thus
the analysis would not catch the illegal reference.
This option tells gcc to inline less but will also
result in a larger kernel.

This option tells gcc to inline less (but it does result in

- Run the section mismatch analysis for each module/built-in.o file.
When we run the section mismatch analysis on vmlinux.o, we
lose valueble information about where the mismatch was
introduced.
Running the analysis for each module/built-in.o file
will tell where the mismatch happens much closer to the
source. The drawback is that we will report the same
mismatch at least twice.
