The patch titled
Subject: kernel/signal.c: protect the SIGNAL_UNKILLABLE tasks from !sig_kernel_only() signals
has been removed from the -mm tree. Its filename was
protect-the-signal_unkillable-tasks-from-sig_kernel_only-signals.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: kernel/signal.c: protect the SIGNAL_UNKILLABLE tasks from !sig_kernel_only() signals
Change sig_task_ignored() to drop the SIG_DFL && !sig_kernel_only()
signals even if force == T. This simplifies the next change and this
matches the same check in get_signal() which will drop these signals
anyway.
