2016-12-11kbuild: fix scripts/adjust_autoksyms.sh* for the no modules caseNicolas Pitre
When CONFIG_TRIM_UNUSED_KSYMS=y and no modules are actually selected, the adjust_autoksyms.sh script fails with: sed: can't read .tmp_versions/*.mod: No such file or directory Let's cope with that case gracefully.

2016-05-10kbuild: fix adjust_autoksyms.sh for modules that need only one symbolNicolas Pitre
When only one symbol was listed and therefore the line didn't contain any space to separate multiple symbols, that symbol got ignored. Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Michal Marek <mmarek@suse.com>

Given the list of exported symbols needed by all modules, we can create a header file containing preprocessor defines for each of those symbols. Also, when some symbols are added and/or removed from the list, we can update the time on the corresponding files used as build dependencies for those symbols. And finally, if any symbol did change state, the corresponding source files must be rebuilt. The insertion or removal of an EXPORT_SYMBOL() entry within a module may create or remove the need for another exported symbol. This is why this operation has to be repeated until the list of needed exported symbols becomes stable. Only then the final kernel and modules link take place.
