The branch main has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=da77382f55129a0304af8985e32d0632eba7cd74 commit da77382f55129a0304af8985e32d0632eba7cd74 Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2021-01-09 20:14:00 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2021-01-09 20:14:00 +0000 arm: revert MAXDSIZ change from 202aea9c82ea This imposes a fairly severe limitation on space available for mmap that was not noticed prior to commit. Unfixed mmap will only map from [data + MAXSIZE, end of user VA space], bringing the amount of usable space down way too low for non-trivial link jobs (for instance).
