Hello

I've uploaded libuv1 with the patch proposed by Tobias. I'll also handle 
libuv0.10 soon.

Thanks to Tobias and Brandon for the help.

All the best

Bug#841354: Fix for hanging epoll_wait on arm64

[Tobias Leich]

Hi,

attached is a fix for the mips-epoll_pwait.diff patch file.
The exiting patch file removes zeroing sigmask, but does not zero 
sigset, the replacement of sigmask.


This causes sigset to hold bogus data and causes a hang.

The attached patch fixes this by moving the zeroing of sigset to before 
the condition, so it runs always.

Tested on arm64 chroot successfully.

Cheers, Tobias
