Package: openssl
Version: 1.0.2g-1ubuntu4.1
Severity: wishlist
Tags: patch

Dear Maintainer,

openssl as built in unstable does not have s390x asm optimisations
enabled for the debian-s390x configuration. The attached patch enables
them. I have verified on the porter box that things remain executable
and operational with 4x speed improvements on some algorithms. Other
distributions have these asm optimistions enabled for a while, and I
have just enabled them in ubuntu too.

The experimental build appears to enabled s390x asm optimisations
already, thanks to the config inheritance from linux-s390x build config
which has them enabled by default.
