Fortunately, Frans said it works for him, and htat distros are using it, so I guess we too should use it.
However, there was one problem other than my own typos in editing scripts - tried to build linux-5.10.13 - CC arch/x86/kernel/apic/apic.o make[3]: *** [scripts/Makefile.build:279: arch/x86/kernel/apic/apic.o] Segmentation fault Feb 8 20:45:13 leshp klogd: [62379.838193] objtool[10870]: segfault at 70 ip 000000000040c13e sp 00007ffd0f655670 error 4 in objtool[402000+11000] followed by a dump of the code bytes. Decided to try 5.10.14 just in case, but that failed the same way, on the same file (freshly extracted 5.10 source, freshly patched to .14). Then I tried 5.11.0-rc7 and that built without problems. My initial guess is that the memory has gone faulty, so I booted memtest86. That is currently part-way through the second of four passes, no errors found so far. Maybe it was the old "cosmic rays" problem, maybe an error will show before memtest86 finishes, or maybe binutils-2.36.1 still has a problem with something in the kernel. I suppose I'd better go back to updating the rest of my scripts so that I can try builds on haswell and zen1 with -march=native.+ ĸen -- Any attempt to brew coffee with a teapot should result in the error code "418 I'm a teapot".
