From: Sebastian Andrzej Siewior Date: Fri, 4 Nov 2016 18:39:38 +0000 (+0100) Subject: kbuild: add -fno-PIE X-Git-Tag: firefly_0821_release~176^2~4^2~12^2~24 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f740b5cc39dd4f3dd301a2b60afe8b70e45554da;p=firefly-linux-kernel-4.4.55.git kbuild: add -fno-PIE 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.
