43fee2b238 kbuild: do not redirect the first prerequisite for filechk
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.

71406883fd s390/kexec_file: Add kexec_file_load system call
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.

fd834e0970 s390/syscalls: add syscalltbl script
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.

857f46bfb0 s390/syscalls: add system call table
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.
