5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Helge Deller deller@gmx.de
commit e5f3e299a2b1e9c3ece24a38adfc089aef307e8a upstream.
Those return codes are only defined for the parisc architecture and are leftovers from when we wanted to be HP-UX compatible.
They are not returned by any Linux kernel syscall but do trigger problems with the glibc strerrorname_np() and strerror() functions as reported in glibc issue #31080.
There is no need to keep them, so simply remove them.
