License cleanup: add SPDX license identifier to uapi header files with no license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

alpha: update syscall macro definitions Other architectures commonly use __NR_umount2 for sys_umount, only ia64 and alpha use __NR_umount here. In order to synchronize the generated tables, use umount2 like everyone else, and add back the old name from asm/unistd.h for compatibility. For shmat, alpha uses the osf_shmat name, we can do the same thing here, which means we don't have to add an entry in the __IGNORE list now that shmat is mandatory everywhere alarm, creat, pause, time, and utime are optional everywhere these days, no need to list them here any more. I considered also adding the regular versions of the get*id system calls that have different names and calling conventions on alpha, which would further help unify the syscall ABI, but for now I decided against that.

/* These are traditionally the names linux-alpha uses for

#define __NR_umount __NR_umount2
#define __NR_osf_shmat __NR_shmat
alpha: add generic get{eg,eu,g,p,u,pp}id() syscalls Alpha has traditionally followed the OSF1 calling conventions here, with its getxpid, getxuid, getxgid system calls returning two different values in separate registers. Following what glibc has done here, we can define getpid, getuid and getgid to be aliases for getxpid, getxuid and getxgid respectively, and add new system call numbers for getppid, geteuid and getegid.

alpha: generate uapi header and syscall table header files System call table generation script must be run to gener- ate unistd_32.h and syscall_table.h files. This patch will have changes which will invokes the script. This patch will generate unistd_32.h and syscall_table.h files by the syscall table generation script invoked by alpha/Makefile and the generated files against the removed files must be identical. The generated uapi header file will be included in uapi/- asm/unistd.h and generated system call table header file will be included by kernel/systbls.S file.

alpha: add __NR_syscalls along with NR_SYSCALLS NR_SYSCALLS macro holds the number of system call exist in alpha architecture. We have to change the value of NR- _SYSCALLS, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_SY- CALLS value. 1. Update NR_SYSCALLS in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_SYS- CALLS until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_SYSCALLS in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_SYSCALLS asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects. Signed-off-by: Firoz Khan <firoz.khan@linaro.org> Signed-off-by: Matt Turner <mattst88@gmail.com>
