kbuild: Add CONFIG_MODVERSIONING and __kcrctab
This patch adds the new config option CONFIG_MODVERSIONING which will
be the new way of checking for ABI changes between kernel and module
code.
This and the following patches are in part based on an initial
implementation by Rusty Russell and I believe some of the ideas go back
to discussions on linux-kbuild, Keith Owens and Rusty.
though I'm not sure I think credit for the basic idea of
storing version info in sections goes to Keith Owens and Rusty.
o Rename __gpl_ksymtab to __ksymtab_gpl since that looks more consistent
and appending _gpl instead of putting it into the middle simplifies
sharing code for EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL()
o Add CONFIG_MODVERSIONING
o If CONFIG_MODVERSIONING is set, add a section __kcrctab{,_gpl}, which
contains the ABI checksums for the exported symbols listed in
__ksymtab{,_crc} Since we don't know the checksums yet at compilation
time, just make them an unresolved symbol which gets filled in by the
linker later.
