commit 587c39e552fbbdfa4ca64c703ad9df7191a76e8e Author: Jan Beulich <jbeulich@xxxxxxxx> AuthorDate: Fri Jun 21 17:16:52 2019 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Fri Jun 21 17:16:52 2019 +0200 AMD/IOMMU: initialize IRQ tasklet only once Don't do this once per IOMMU, nor after setting up the IOMMU interrupt (which will want to schedule this tasklet). In fact it can be initialized at build time.
