Masahiro Yamada d082402e21 kbuild: remove meaningless 'targets' in ./Kbuild
timeconst.h is generated by $(call filechk,...), missing-syscalls and
old-atomics are invoked by $(call cmd,...)

None of them needs to be added to 'targets'.

Kbuild for top-level directory of the kernel

Generate bounds.h

bounds-file := include/generated/bounds.h

always := $(bounds-file) targets := kernel/bounds.s

$(bounds-file): kernel/bounds.s FORCE $(call filechk,offsets,LINUX_BOUNDS_H)

Generate timeconst.h

timeconst-file := include/generated/timeconst.h

filechk_gentimeconst = echo $(CONFIG_HZ) | bc -q $<

$(timeconst-file): kernel/time/timeconst.bc FORCE $(call filechk,gentimeconst)

Generate asm-offsets.h

offsets-file := include/generated/asm-offsets.h

always += $(offsets-file) targets += arch/$(SRCARCH)/kernel/asm-offsets.s

arch/$(SRCARCH)/kernel/asm-offsets.s: $(timeconst-file) $(bounds-file)

$(offsets-file): arch/$(SRCARCH)/kernel/asm-offsets.s FORCE $(call filechk,offsets,ASM_OFFSETS_H)

Check for missing system calls

always += missing-syscalls

quiet_cmd_syscalls = CALL $< cmd_syscalls = $(CONFIG_SHELL) $< $(CC) $(c_flags) $(missing_syscalls_flags)

missing-syscalls: scripts/checksyscalls.sh $(offsets-file) FORCE $(call cmd,syscalls)

Check atomic headers are up-to-date

always += old-atomics

quiet_cmd_atomics = CALL $< cmd_atomics = $(CONFIG_SHELL) $<

Keep these three files during make clean

no-clean-files := $(bounds-file) $(offsets-file) $(timeconst-file)
