Like 4.9.y it builds clean except for a couple of stack frame size warnings and this one that continues to puzzle me.
/bin/sh: 1: /home/buildslave/workspace/kernel-builder/arch/x86/defconfig/allmodconfig+CONFIG_OF=n/label/builder/next/build-x86/tools/objtool//fixdep: Permission denied
Jiri? Josh?
hum, looks like it imight be related to this fix we did for perf: abb26210a395 perf tools: Force fixdep compilation at the start of the build
it's forcing fixdep to be build as first.. having it as a simple dependency (which AFAICS is objtool case), the make -jX occasionaly raced on high cpu servers, and executed unfinished binary, hence the permission fail
It's probably another variation of this bug, but the commit you cite got merged into 4.10-rc1, while the problem still persists in mainline (4.11-rc2+).
the problem is in objtool build right? the fix was for perf build
Ah, got it. Yes, that must be it then. I supposed we coul duplicate what you did for perf in objtool, but a cleaner way would be to generalize it for all of tools/, right?
This is a shot in the dark, since I don't have a way to recreate, but can you try the following patch? This should make sure that objtool only tries to build fixdep once.
