s390: add a few more SPDX identifiers Add the correct SPDX license to a few more files under arch/s390 and drivers/s390 which have been missed to far. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

s390/syscalls: use generated syscall_table.h and unistd.h header files Update the uapi/asm/unistd.h to include the generated compat and 64-bit version of the unistd.h and, as well as, the unistd_nr.h header file. Also remove the arch/s390/kernel/syscalls.S file and use the generated system call table, syscall_table.h, instead.

y2038: s390: Remove unneeded ipc uapi header files The s390 msgbuf/sembuf/shmbuf header files are all identical to the version from asm-generic. This patch removes the files and replaces them with 'generic-y' statements, to avoid having to modify each copy when we extend sysvipc to deal with 64-bit time_t in 32-bit user space. Note that unlike alpha and ia64, the ipcbuf.h header file is slightly different here, so I'm leaving the private copy. To deal with 32-bit compat tasks, we also have to adapt the definitions of compat_{shm,sem,msg}id_ds to match the changes to the respective asm-generic files.

s390: use generic uapi/asm/swab.h clang doesn't like s390 specific inline assembler constraints. These are present in our arch specific uapi/asm/swab.h which again is required by some ebpf test cases. For current compiler versions the generic swab.h already makes use of gcc's builtin functions. Therefore we can simply remove our own header file and use the generic one. This will generate worse code if used with compilers before gcc 4.8, which has no __builtin_bswap16(); or before gcc v4.4, which has no __builtin_bswap[32|64](). For these cases a C implementation fallback would be used which generates more code, but is still correct (170KB extra code for gcc 4.3 with performance_defconfig). However given that we need (and want) to get rid of the inline assemblies anyway in order to be able to use clang, the above is just a minor drawback if old gcc compilers are used. With current compilers there is close to zero difference, except for three btrfs bit functions which generate more out-of-line code. The generated code looks still correct and also uses the s390 specific byteswap instructions.

signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE Rework the defintion of struct siginfo so that the array padding struct siginfo to SI_MAX_SIZE can be placed in a union along side of the rest of the struct siginfo members. The result is that we no longer need the __ARCH_SI_PREAMBLE_SIZE or SI_PAD_SIZE definitions. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
