__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 information. 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_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'll count the number of syscalls and keep it in a generated 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 name also changed form __NR_Linux_syscalls to __NR_syscalls 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.
