Thank you for the report Michael, I have no PPC toolchain so I have not tested this one. Added now.

Just one question, with this release, no -rc patch was emitted. Do you think you would have built it in time if I had provided a way to retrieve the -rc patch ? I'm asking because it's much more difficult right now to put it somewhere, but for instance it can be emitted with the announcement mail.

Regards,
Willy

Willy,

No problem.

I would test it but to fit with my work flow I'd really like the rc in a git tree. I've asked gregkh to do this in the past, but he's not been able to. Hence I only test the final releases.

Thanks,
Mikey

Just pimping the cross toolchains I build:

Hi Tony,

Thanks for this pointer, it can indeed be quite useful from time to time, especially to check gcc-related regressions.

That said, I'd rather not install a number of toolchains for systems I can't test. I regularly build for i386/x86_64/arm with real configs that I can boot a machine on when I have a doubt. Building random configs do not always test all source code, especially on architectures which support a wide variety of embedded platforms.

But I'm keeping the URL, Thanks :-)
Willy
