    MIPS: Use set_current_blocked() and block_sigmask() · 8598f3cd
    Matt Fleming authored
    As described in e6fa16ab ("signal: sigprocmask() should do
    retarget_shared_pending()") the modification of current->blocked is
    incorrect as we need to check whether the signal we're about to block
    is pending in the shared queue.
    
    Also, use the new helper function introduced in commit 5e6292c0
    ("signal: add block_sigmask() for adding sigmask to current->blocked")
    which centralises the code for updating current->blocked after
    successfully delivering a signal and reduces the amount of duplicate
    code across architectures. In the past some architectures got this
    code wrong, so using this helper function should stop that from
    happening again.
