kbuild: use assignment instead of define ... endef for filechk_* rules

2019-01-06T01:22:35Z

You do not have to use define ... endef for filechk_* rules. For simple cases, the use of assignment looks cleaner, IMHO. I updated the usage for scripts/Kbuild.include in case somebody misunderstands the 'define ... endif' is the requirement. Signed-off-by: Masahiro Yamada Acked-by: Heiko Carstens

kbuild: do not redirect the first prerequisite for filechk

2018-07-28T01:34:10Z

Currently, filechk unconditionally opens the first prerequisite and redirects it as the stdin of a filechk_* rule. Hence, every target using $(call filechk,...) must list something as the first prerequisite even if it is unneeded. '< $<' is actually unneeded in most cases. Each rule can explicitly adds it if necessary. Signed-off-by: Masahiro Yamada

s390/kexec_file: Add kexec_file_load system call

2018-04-16T07:10:22Z

This patch adds the kexec_file_load system call to s390 as well as the arch specific functions common code requires to work. Loaders for the different file types will be added later. Signed-off-by: Philipp Rudo Signed-off-by: Martin Schwidefsky

s390/syscalls: add Makefile to generate system call header files

s390/syscalls: add syscalltbl script

2018-01-23T06:36:51Z

Introduce the syscalltbl script to read the system call table and generate respective uapi unistd.h header files. Also it generates the contents syscalls.S - the real system call table - which is included by arch/s390/kernel/entry.S.

s390/syscalls: add system call table

2018-01-23T06:36:50Z

Add a table that lists available system calls and their entry functions. With this change, adding new system calls become fairly easy: 1. Add a new table entry consisting of the system call number, abi (common or 64/31 bit only), and the entry functions. 2. If necessary, create a compat syscall wrapper.
