Subject: vfio: Add explicit alignments in vfio_iommu_spapr_tce_create
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=77d6bd47cc2824af016086c2bd4650685b159e22;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

vfio: Add explicit alignments in vfio_iommu_spapr_tce_create

The vfio_iommu_spapr_tce_create struct has 4x32bit and 2x64bit fields
which should have resulted in sizeof(fio_iommu_spapr_tce_create) equal
to 32 bytes. However due to the gcc's default alignment, the actual
size of this struct is 40 bytes.

This fills gaps with __resv1/2 fields.

This should not cause any change in behavior.
