Subject: uapi/linux/prctl: provide macro definitions for the PR_SCHED_CORE
 type argument
Git-commit: 61bc346ce64a3864ac55f5d18bdc1572cda4fb18
Patch-mainline: v5.16-rc1
References: bsc#1194659

Commit 7ac592aa35a684ff ("sched: prctl() core-scheduling interface")
made use of enum pid_type in prctl's arg4; this type and the associated
enumeration definitions are not exposed to userspace.  Christian
has suggested to provide additional macro definitions that convey
the meaning of the type argument more in alignment with its actual
usage, and this patch does exactly that.

Get rid of the non-uapi bits, and tweak the path so that it applies.
