9 * glibc-2.x. Hence the #ifdef __KERNEL__ ugliness.

58 * SA_ONSTACK indicates that a registered stack_t will be used.
59 * SA_RESTART flag to get restarting signals (which were the default long ago)
60 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
61 * SA_RESETHAND clears the handler when the signal is delivered.
62 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
63 * SA_NODEFER prevents the current signal from being masked in the handler.
65 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
66 * Unix names RESETHAND and NODEFER respectively.

88 * The minimum stack size needs to be fairly large because we want to
89 * be sure that an app compiled for today's CPUs will continue to run
90 * on all future CPU models. The CPU model matters because the signal
91 * frame needs to have space for the complete machine state, including
92 * all physical stacked registers. The number of physical stacked
93 * registers is CPU model dependent, but given that the width of
94 * ar.rsc.loadrs is 14 bits, we can assume that they'll never take up
95 * more than 16KB of space.

101 * incorrect value and fix libc only.
