__NR_Linux_syscalls macro holds the number of system call exist in PARISC architecture. This macro is currently the part of uapi/asm/unistd.h file. We have to change the value of __NR_Linux_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 number of system call inform- ation. So we have two option to update __NR_Linux_syscalls value. 1. Update __NR_Linux_syscalls in uapi/asm/unistd.h manually by counting the no.of system calls. No need to update __NR_Linux_syscalls until we either add a new system call or delete an 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 gener- ated file. In this case we don't need to explicitly update __NR_Linux_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I moved the __NR_Linux_syscalls macro from uapi/asm/unistd.h to asm/ unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_sys- calls 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.
