* [PATCH] sigprocmask.2: do not specify an exact value of rt_sigprocmask's 4th argument

As sizeof(kernel_sigset_t) is not the same for all architectures,
it would be better not to mention any numbers as its value.

why not add this information like:
Note: sizeof(kernel_sigset_t) is not the same for all architectures
