[Qemu-devel] [PATCH v2 1/2] s390x/css: use macro for event-information pending error recover code |
Date: |
Tue, 1 Aug 2017 09:57:26 +0200 |
Let's use a macro for the ERC (error recover code) when generating a
Channel Subsystem Event-information pending CRW (channel report word).
While we are at it, let's also add all other ERCs.
