I have just built my "pending-fixes" branch (which I have pushed out to the linux-next tree on git.kernel.org), then merged your tree and then built again: $ make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu- O=../obj -j15 -O make[1]: Entering directory '/home/sfr/kernels/obj' GEN Makefile make[1]: Leaving directory '/home/sfr/kernels/obj' make[1]: Entering directory '/home/sfr/kernels/obj' UPD include/generated/compile.h make[1]: Leaving directory '/home/sfr/kernels/obj' DESCEND objtool make[2]: *** No rule to make target 'objtool/objtool'. Stop. make[1]: *** [/home/sfr/kernels/test/Makefile:1361: tools/objtool/objtool] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [Makefile:222: __sub-make] Error 2 (I actually did this on my laptop rather than my build machine, but the compiles are still cross compiles - just from arm64 instead of powerpc64le). -- Cheers, Stephen Rothwell
