2.31: glibc master is now kinda, sorta, frozen

[Siddhesh Poyarekar <siddhesh@gotplt.org>]

Hello,

It's almost the end of the year where I am (and already 2020 further
east, hope your new year resolutions have not broken already!) and the
much anticipated release freeze is here, kinda.

If your patch has been reviewed and acked, please commit it as soon as
you can.  There are 4 release blockers in the list and we need to try to
get them off the list one way or another by the end of the week.

- iconv: rewrite option parsing
    https://sourceware.org/ml/libc-alpha/2019-12/msg00613.html

Arjun, how's this going?  I see a v2 but no reviews.  I'll review this
on Thursday if nobody gets to it by then.

- New DSO sorting algorithm and test script
    https://sourceware.org/ml/libc-alpha/2019-07/msg00472.html
    https://sourceware.org/ml/libc-alpha/2019-07/msg00473.html

Chung-Lin, based on Carlos' review comments, a new revision looks like a
fair amount of work, which makes this unsuitable as a release blocker.
I suggest we drop this from the blocker list so that you're not rushed
into pushing a patchset.  Please do post the patch for review in the
meantime since we're still OK to do reviews; just that you can only
commit after the 2.31 release is done.

Of course, if you want (and if the patch does not have ABI implications)
we can always backport to the 2.31 branch after the release.

- vDSO refactor and fixes
    https://sourceware.org/ml/libc-alpha/2019-12/msg00597.html

Adhemerval, I see some reviews and change requests.  Are you waiting for
reviews on the rest of your patches or do you intend to post a v3
patchset?  I can help with reviews on Thursday if nobody gets to it by then.

- Add libm_alias_finite for _finite symbols
    https://sourceware.org/ml/libc-alpha/2019-10/msg00627.html
    It moves the _finite symbol to compat symbols and not enable them
    for newer architectures.

Adhemerval, would you be OK with dropping this off the blocker list if a
review suggests that the patchset needs an update?  I'll do a review on
Thursday and if there are no changes needed, you can push it in.
However if the patchset needs changes, I'll help with reviews of the
updated patchset too, but you can commit after the 2.31 release.  Does
that sound reasonable?
