For ARM, modpost fails to detect some types of section mismatches.

  [test code]

    .section .init.data,"aw"
    bar:
            .long 0

    .section .data,"aw"
    .globl foo
    foo:
            .long bar - .

It is apparently a bad reference, but modpost does not report anything.

The test code above produces the following relocations.

  Relocation section '.rel.data' at offset 0xe8 contains 1 entry:
   Offset     Info    Type            Sym.Value  Sym. Name
  00000000  00000403 R_ARM_REL32       00000000   .init.data

Currently, R_ARM_REL32 is just skipped.

Handle it like R_ARM_ABS32.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
