Hello, I have 3 different things in this patchset. All arch specific, but all involve kbuild changes, so I'd like to discuss them with kbuild maintainers. The goal has been to improve long standing linking difficulties with the powerpc kernel. * First, building kernel using thin archives rather than incremental linking. This seems quite clean and is per-arch, so I hope it should not be too controversial. * Second, building kernel using -ffunction-sections -fdata-sections, --gc-sections. Yes, I'm spinning the wheel again. It was motivated by tiny codesize regression in the first patch, but the results seem too good to ignore. * Third, allowing architecture to run a tool over module after it has been linked. Powerpc wants to use it in order to relocate "alternate code" instructions that get don't get linked at their runtime address. No idea if this is the right approach wrt kbuild, but it seems to work. I have included the powerpc code for the first two as a reference. The third is much bigger and mostly uninteresting for this cc list, but it can be found here: https://patchwork.ozlabs.org/patch/651006/ Comments appreciated.
