-   directly rather than via glibc. The sigaction structure that the
-   syscall uses is a different shape from the one in userland and not
-   visible to us in a header file so we define it here.
-   Additionally we want a proper prototype for the handler function
-   with the struct sigcontext pointer passed by the kernel as the 2nd
-   argument, which isn't there in userland headers.
-
-   Note that we explicitly avoid the SA_SIGINFO flag in INIT_SEGV and
-   INIT_FPE below. Using the ucontext pointer passed as 3rd argument
-   of a SA_SIGINFO type handler would need complicated backwards
-   compatibility hacks in MAKE_THROW_FRAME, as the ucontext layout
-   on PPC changed during the 2.5 kernel series.  */
