-Subject: [PATCH] kbuild: Steal gcc's pie from the very beginning
-
-commit c6a385539175ebc603da53aafb7753d39089f32e upstream.
-
-So Sebastian turned off the PIE for kernel builds but that was too late
-- Kbuild.include already uses KBUILD_CFLAGS and trying to disable gcc
-options with, say cc-disable-warning, fails:
-
- gcc -D__KERNEL__ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs
- ...
- -Wno-sign-compare -fno-asynchronous-unwind-tables -Wframe-address -c -x c /dev/null -o .31392.tmp
- /dev/null:1:0: error: code model kernel does not support PIC mode
-
-because that returns an error and we can't disable the warning. For
-example in this case:
-
-KBUILD_CFLAGS += $(call cc-disable-warning,frame-address,)
-
-which leads to gcc issuing all those warnings again.
-
-So let's turn off PIE/PIC at the earliest possible moment, when we
-declare KBUILD_CFLAGS so that cc-disable-warning picks it up too.
-
-Also, we need the $(call cc-option ...) because -fno-PIE is supported
-since gcc v3.4 and our lowest supported gcc version is 3.2 right now.
