Changes since v3: 1) Rebased onto Linux 6.10-rc6+. 2) Added Muhammad's acks for the series. Cover letter for v3: Hi, Dave Hansen, Muhammad Usama Anjum, here is the combined series that we discussed yesterday [1]. As I mentioned then, this is a bit intrusive--but no more than necessary, IMHO. Specifically, it moves some clang-un-inlineable things out to "pure" assembly code files. I've tested this by building with clang, then running each binary on my x86_64 test system with today's 6.10-rc1, and comparing the console and dmesg output to a gcc-based build without these patches applied. Aside from timestamps and virtual addresses, it looks identical. Earlier cover letter: Just a bunch of build and warnings fixes that show up when building with clang. Some of these depend on each other, so I'm sending them as a series. Changes since v2: 1) Dropped my test_FISTTP.c patch, and picked up Muhammad's fix instead, seeing as how that was posted first. 2) Updated patch descriptions to reflect that Valentin Obst's build fix for LLVM [1] has already been merged into Linux main. 3) Minor wording and typo corrections in the commit logs throughout. Changes since the first version: 1) Rebased onto Linux 6.10-rc1 Enjoy!
