Yes, the initial patch was sent prior the release dates. The only bit I
would some comments is why adding '__glibc_reserved1' fields (alignment
maybe?).

That's because __private_ss offset from thread pointer is hardcoded in gcc, and needs to be constant regardless of glibc configuration (it works out to 0x20 for 31-bit, 0x38 for 64-bit) - the same thing is done in i386 and x86_64 tcbhead.

This is okay for s390.

Adhemerval, is this okay for 2.23?

It is needed to enable split-stack support on s390 (See gcc bug #68191).

I don't have push access, how do I get the patch applied?

Stefan Liebler should be able to push it for you.

Cheers,
Carlos.



I've applied the patch.
