__NR_syscalls holds the number of system call exist in microblaze 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- _syscalls 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 moved the __NR_syscalls macro from asm/unistd.h to uapi- /asm/unistd.h. 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: Michal Simek <michal.simek@xilinx.com>
