iommu/vt-d: Treat PAGE_SNOOP and PWSNP separately

2026-02-06T10:01:00Z

The PASID_FLAG_PAGE_SNOOP and PASID_FLAG_PWSNP constants are identical. This will cause the pasid code to always set both or neither of the PGSNP and PWSNP bits in PASID table entries. However, PWSNP is a reserved bit if SMPWC is not set in the IOMMU's extended capability register, even if SC is supported. This has resulted in DMAR errors when testing the iommufd code on an Arrow Lake platform. With this patch, those errors disappear and the PASID table entries look correct.
