    signal: Add restore_user_sigmask() · 854a6ed5
    Deepa Dinamani authored
    Refactor the logic to restore the sigmask before the syscall
    returns into an api.
    This is useful for versions of syscalls that pass in the
    sigmask and expect the current->sigmask to be changed during
    the execution and restored after the execution of the syscall.
    
    With the advent of new y2038 syscalls in the subsequent patches,
    we add two more new versions of the syscalls (for pselect, ppoll
    and io_pgetevents) in addition to the existing native and compat
    versions. Adding such an api reduces the logic that would need to
    be replicated otherwise.
