Subject: [PATCH v5 1/3] PCI: hv: Add __aligned(8) to struct retarget_msi_interrupt
Date: Fri, 1 Mar 2019 06:56:24 +0000 [thread overview]
Message-ID: <5f6f7fa3d287867ae4c2220ff7235efe544cdd6e.1551421809.git.m.maya.nakamura@gmail.com> (raw)
In-Reply-To: <cover.1551421809.git.m.maya.nakamura@gmail.com>
Because Hyper-V requires that hypercall arguments be aligned on an 8
byte boundary, add __aligned(8) to struct retarget_msi_interrupt.
