m68k: coldfire/device.c: only build FEC when HW macros are defined

2024-12-05T13:02:24+00:00

[ Upstream commit 63a24cf8cc330e5a68ebd2e20ae200096974c475 ] When CONFIG_FEC is set (due to COMPILE_TEST) along with CONFIG_M54xx, coldfire/device.c has compile errors due to missing MCFEC_* and MCF_IRQ_FEC_* symbols. Make the whole FEC blocks dependent on having the HW macros defined, rather than on CONFIG_FEC itself. This fix is very similar to commit e6e1e7b19fa1 ("m68k: coldfire/device.c: only build for MCF_EDMA when h/w macros are defined") Fixes: b7ce7f0d0efc ("m68knommu: merge common ColdFire FEC platform setup code") To: Greg Ungerer To: Geert Uytterhoeven Cc: linux-m68k@lists.linux-m68k.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Antonio Quartulli Signed-off-by: Greg Ungerer Signed-off-by: Sasha Levin

arch: include linux/cpu.h for trap_init() prototype

some architectures run into a -Wmissing-prototypes warning for trap_init() arch/microblaze/kernel/traps.c:21:6: warning: no previous prototype for 'trap_init' [-Wmissing-prototypes] Include the right header to avoid this consistently, removing the extra declarations on m68k and x86 that were added as local workarounds already.

m68k: Replace GPL 2.0+ README.legal boilerplate with SPDX

2023-10-06T08:03:04+00:00

Upstream Linux never had a "README.legal" file, but it was present in early source releases of Linux/m68k. It contained a simple copyright notice and a link to a version of the "COPYING" file that predated the addition of the "only valid GPL version is v2" clause. Get rid of the references to non-existent files by replacing the boilerplate with SPDX license identifiers.

m68k: Check syscall_trace_enter() return code

2023-01-30T15:40:15+00:00

Check return code of syscall_trace_enter(), and skip syscall if -1. Return code will be left at what had been set by ptrace or seccomp (in regs->d0). No regression seen in testing with strace on ARAnyM.

kbuild: use obj-y instead extra-y for objects placed at the head

2022-10-02T09:04:05+00:00

The objects placed at the head of vmlinux need special treatments: - arch/$(SRCARCH)/Makefile adds them to head-y in order to place them before other archives in the linker command line. - arch/$(SRCARCH)/kernel/Makefile adds them to extra-y instead of obj-y to avoid them going into built-in.a. This commit gets rid of the latter. Create vmlinux.a to collect all the objects that are unconditionally linked to vmlinux. The objects listed in head-y are moved to the head of vmlinux.a by using 'ar m'. With this, arch/$(SRCARCH)/kernel/Makefile can consistently use obj-y for builtin objects. There is no *.o that is directly linked to vmlinux. Drop unneeded code in scripts/clang-tools/gen_compile_commands.py. $(AR) mPi needs 'T' to workaround the llvm-ar bug. The fix was suggested by Nathan Chancellor [1].
