- Renamed IMAGE_BASE to LD_IMAGE_BASE_OPT. - Moved "-fcommon" to KLIBCREQFLAGS in scripts/Kbuild.klibc. - Remove "dash" warning fixes which have been upstreamed. - Conditionalize the inclusion of compiler flags by using the proper compiler name or "cc-option". - Added "-Werror" to "cc-option" to catch flags that...

Hi Peter, Thanks for the response. If we set aside the discussion of the relationship between sections and the application of the "location" or "at" attribute for a moment, do you have any objections to the proposed method of encoding metadata information about symbols (whether they are associated with actual data objects, functions, or sections) in the ELF object file?
