From dce69259aebbc43b248d3593e46bdc7d4d33d94c Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 12 Oct 2021 15:33:09 +0200 Subject: x86/xen: Remove redundant irq_enter/exit() invocations All these handlers are regular device interrupt handlers, so they already went through the proper entry code which handles this correctly.
