The "tile" changes for the core were merged (thanks again to Roland) and I
have the glibc-ports changes ready to push up; I'm just waiting to see if
anyone has any other issues with the current set of patches before I do
so. (I don't think they're very controversial.)
I've appended a list of commits for master that are relevant; for ports,
after I commit, I think it's safe to just sweep up all the changes for the
relevant sysdeps pieces for tile (sysdeps/tile,
sysdeps/unix/sysv/linux/tile, and sysdeps/unix/sysv/linux/generic) since it
certainly can't break anything else.
Let me know if there's anything I can do to make it easier for you to
consider doing this, or if you have any concerns with the safety of pulling
in the changes in question. In particular I'll try setting up a 2.15
branch that just has the tile changes integrated into it, but I haven't
played with cherry-picking, git-merge-changelog, etc., before so we'll see
how that goes. :-)
Thanks!
