Subject: kbuild: add -fno-PIE
|
||
Origin: https://git.kernel.org/cgit/linux/kernel/git/mmarek/kbuild.git/commit?id=8ae94224c9d72fc4d9aaac93b2d7833cf46d7141
|
||
Bug-Debian: https://bugs.debian.org/841368
|
||
|
||
Debian started to build the gcc with -fPIE by default so the kernel
|
||
build ends before it starts properly with:
|
||
|kernel/bounds.c:1:0: error: code model kernel does not support PIC mode
|
||
|
||
Also add to KBUILD_AFLAGS due to:
|
||
|
||
|gcc -Wp,-MD,arch/x86/entry/vdso/vdso32/.note.o.d … -mfentry -DCC_USING_FENTRY … vdso/vdso32/note.S
|
||
|arch/x86/entry/vdso/vdso32/note.S:1:0: sorry, unimplemented: -mfentry isn’t supported for 32-bit in combination with -fpic
|
||
|
||
Tagging it stable so it is possible to compile recent stable kernels as
|
||
well.
