kbuild: rename hostprogs-y/always to hostprogs/always-y

2020-02-03T16:53:07+00:00

In old days, the "host-progs" syntax was used for specifying host programs. It was renamed to the current "hostprogs-y" in 2004. It is typically useful in scripts/Makefile because it allows Kbuild to selectively compile host programs based on the kernel configuration. This commit renames like follows: always -> always-y hostprogs-y -> hostprogs So, scripts/Makefile will look like this: always-$(CONFIG_BUILD_BIN2C) += ... always-$(CONFIG_KALLSYMS) += ... ... hostprogs := $(always-y) $(always-m) I think this makes more sense because a host program is always a host program, irrespective of the kernel configuration. We want to specify which ones to compile by CONFIG options, so always-y will be handier. The "always", "hostprogs-y", "hostprogs-m" will be kept for backward compatibility for a while.

s390: add support for IBM z15 machines

2019-09-13T10:19:14+00:00

Add detection for machine types 0x8562 and 8x8561 and set the ELF platform name to z15. Add the miscellaneous-instruction-extension 3 facility to the list of facilities for z15. And allow to generate code that only runs on a z15 machine. Reviewed-by: Christian Borntraeger Signed-off-by: Martin Schwidefsky Signed-off-by: Heiko Carstens

s390: drop meaningless 'targets' from tools Makefile

2019-06-04T13:03:38+00:00

'targets' should be specified to include .*.cmd files to evaluate if_changed or friends. Here, facility-defs.h and dis-defs.h are generated by filechk. Because filechk does not generate .*.cmd file, the 'targets' addition is meaningless. The filechk correctly updates the target when its content is changed.

s390: drop redundant directory creation from tools Makefile

2019-06-04T13:03:34+00:00

As you can see in scripts/Kbuild.include, the filechk creates the parent directory of the target as needed. This Makefile does not need to explicitly create the directory. Signed-off-by: Masahiro Yamada Signed-off-by: Heiko Carstens

s390: drop unneeded -Wall addition from tools Makefile

2019-06-04T13:03:29+00:00

The top level Makefile adds -Wall globally for all host tools: KBUILD_HOSTCFLAGS := -Wall -Wmissing-prototypes -Wstrict-prototypes -O2 \ I see two "-Wall" added for compiling these tools. Of course, it is allowed to pass the same option multiple times, but we do not need to do so. Signed-off-by: Masahiro Yamada Signed-off-by: Heiko Carstens

s390: do not pass $(LINUXINCLUDE) to gen_opcode_table.c

2019-06-04T13:03:22+00:00

I guess HOSTCFLAGS_gen_opcode_table.o was blindly copied from HOSTCFLAGS_gen_facilities.o The reason of adding $(LINUXINCLUDE) to HOSTCFLAGS_gen_facilities.o is because gen_facilities.c references some CONFIG options. (Kbuild does not cater to this for host tools automatically.) On the other hand, gen_opcode_table.c does not reference CONFIG options at all. So, there is no good reason to pass $(LINUXINCLUDE).
