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. */
