Honestly, I think we should back out (revert):

1. 54878b80f3e332f3420132f8b4c74412fc29ef6b
2. 985c0d1903c173b896674b30480992e2414b8aa0
3. 418a3a45773a2a3fee1125534a073cec62c88b1e

Then go about:
1. implement prcntl
2. implement getauxval
3. implement sysconf
4. implement mincore

as 4 distinct commits/PRs.  We should not have landed 418a3a45773a2a3fee1125534a073cec62c88b1e using EXEC_PAGESIZE; it was a mistake of mine to have approved #73704
