From: Sebastian Andrzej Siewior <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit 8ae94224c9d72fc4d9aaac93b2d7833cf46d7141 upstream. 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.
