I’m not opposed to this patch, but isn’t this what core files are for?

I also pushed the patch upstream: https://github.com/wulf7/utouch/commit/0723a532d644faeb7c3aaf4fbbcf122af2282896 so it is possible to just bump PORTVERSION to 0.0.4

@sunpoet fixed it in https://cgit.freebsd.org/ports/commit/?id=b1e525f8607ab2c9605a68a8208e1c24bf41744a

Seems reasonable to me.

Note that -flto doesn't actually LTO system libraries, because we do not yet provide LLVM IR libraries. If you put an explicit_bzero implementation in your test code though you can get it to be eliminated. As it stands today for normal use (linking against libc as usual) it will not be eliminated.

I wasn't sure about adding new functions to libraries in stable/ branches, particularly to notify ports of the existence. I see now that stable/13 has the FBSD_1.7 in the top level Symbol.map anyway, so no issue.

You just merge it when you think that there is enough testing done in head, as usual. Or, is there some more background context I am not aware of?

I think I saw the errors you are mentioning earlier than 1400058.

I have a patch to use an IPI in pmap_update_entry. The variable to exit the loop is from the caller stack so would break exceptions in the same way if we promote/demote the page.

The main issue is deciding on which memory will need to use an IPI. I prototyped using a software flag in the pte, however this is likely to stop promotion as pmap_promote_l2 checks these attributes are identical over the entire range before promotion.

I don't remember it already, but you seem to be right, I see the 24 hours limit removed in 40e794ab19fb 9 years ago.

So, spent a few minutes looking into this, my testing was done on:

New patch has addressed a few of the comments.

Thanks, will address a few of the comments.
