commit fd87b7783802b45cdd261b273e6b2b792823064d upstream.
The devmem socket options and socket control message definitions introduced in the TCP devmem series[1] incorrectly continued the socket definitions for arch/parisc.
The UAPI change seems safe as there are currently no drivers that declare support for devmem TCP RX via PP_FLAG_ALLOW_UNREADABLE_NETMEM. Hence, fixing this UAPI should be safe.
Fix the devmem socket options and socket control message definitions to reflect the series followed by arch/parisc.
