Hendrik Brueckner	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.

Hendrik Brueckner	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.
