UML: define RUNTIME_DISCARD_EXIT With CONFIG_VIRTIO_UML=y, GNU ld < 2.36 fails to link UML vmlinux (w/wo CONFIG_LD_SCRIPT_STATIC). `.exit.text' referenced in section `.uml.exitcall.exit' of arch/um/drivers/virtio_uml.o: defined in discarded section `.exit.text' of arch/um/drivers/virtio_uml.o collect2: error: ld returned 1 exit status This fix is similar to the following commits: - 4b9880dbf3bd ("powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT") - a494398bde27 ("s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36") - c1c551bebf92 ("sh: define RUNTIME_DISCARD_EXIT") Fixes: 99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv") Reported-by: SeongJae Park <sj@kernel.org> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: SeongJae Park <sj@kernel.org> Signed-off-by: Richard Weinberger <richard@nod.at>

arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0 Albin Tonnerre <albin.tonnerre@free-electrons.com> reported: Bash 4 filters out variables which contain a dot in them. This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.

[PATCH] uml: tidy biarch gcc support On top of the previous biarch changes for UML, this makes the preprocessor changes a bit cleaner. Specify the 64-bit build in CPPFLAGS on the x86_64 SUBARCH, rather than #undef'ing i386. Compile-tested with i386 and x86_64 SUBARCHs.

[PATCH] uml: fix biarch gcc build on x86_64 I run an x86_64 kernel with i386 userspace (Ubuntu Dapper) and decided to try out UML today. I found that UML wasn't quite aware of biarch compilers (which Ubuntu i386 ships). A fix similar to what was done for x86_64 should probably be committed (see http://marc.theaimsgroup.com/?l=linux-kernel&m=113425940204010&w=2). Without the FLAGS changes, the build will fail at a number of places and without the LINK change, the final link will fail.
