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

2023-10-06T08:03:04Z

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

2023-01-30T15:40:15Z

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

2022-10-02T09:04:05Z

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].

m68knommu: fix non-specific 68328 choice interrupt build failure

2022-09-26T00:27:53Z

Compiling for a classic m68k non-MMU target with no specific CPU selected fails with the following error: arch/m68k/68000/ints.c: In function 'process_int': >> arch/m68k/68000/ints.c:82:30: error: 'ISR' undeclared (first use in this function) 82 | unsigned long pend = ISR; | ^~~ This interrupt handling code is specific to the 68328 family of 68000 parts. There is a couple of variants (68EZ328, 68VZ328) and the common ancestor of them the strait 68328. The code here includes a specific header for each variant type. But if none is selected then nothing is included to supply the appropriate register and bit flags defines. Rearrange the includes so that at least one type is always included. At the very least the 68328 base type should be the fallback, so make that true. Reported-by: kernel test robot Reviewed-by: Geert Uytterhoeven Signed-off-by: Greg Ungerer
