No, this patch is not in our tree. Do we want it?

Yes. Please apply the patch.

Thanks.

Sure.
Just want to make sure.
Is the patch this one?

I think 2 patches are needed.

"Reallocate DTV if the current DTV isn't big enough"

"Resize DTV if the current DTV isn't big enough"

Sorry. I guess the 2 patches actually refers to the same CL.

Yes. The link is https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=d8dd00805b8f3a011735d7a407097fb1c408d867

The patch applies cleanly but it depends on other patches. It may take some time to apply it to our tree.

glibc: backport a patch requested by ChromeCast

This backports the upstream commit
commit d8dd00805b8f3a011735d7a407097fb1c408d867

    Resize DTV if the current DTV isn't big enough

And it replaces a call to atomic_load_acquire() with
__atomic_load_n(). The former macro was introduced by another patch and
glibc 2.19 could not build with that one because a macro was not defined.

The patch that adds atomic_load_acquire() was
commit ff8714269c9312d9164456279a56b6f6c47e2771

    Add atomic operations similar to those provided by C11.

BUG= chromium:606067 
TEST=emerge glibc passes.
     cbuildbot chromiumos-sdk falco-release daisy-release
     test case in the bug entry passes.
