-/* These are the hard limits of the kernel. These values should not be

-/* In the Linux kernel version 3.17, and glibc 2.21, the signal numbers
- were rearranged in order to make hppa like every other arch. Previously
- we started __SIGRTMIN at 37, and that meant several pieces of important
- software, including systemd, would fail to build. To support systemd we
- removed SIGEMT and SIGLOST, and rearranged the others according to
- expected values. This is technically an ABI incompatible change, but
- because zero applications use SIGSTKFLT, SIGXCPU, SIGXFSZ and SIGSYS
- nothing broke. Nothing uses SIGEMT and SIGLOST, and they were present
- for HPUX compatibility which is no longer supported. Thus because
- nothing breaks we don't do any compatibility work here. */
