Subject: [PATCH v1 0/2] iommu/vt-d: Remove dmar_readl(), etc
Date: Tue, 17 Feb 2026 15:44:36 -0600 [thread overview]
Message-ID: <20260217214438.3395039-1-bhelgaas@google.com> (raw)
Remove dmar_readl() and similar wrappers because they add nothing over
readl() and are used inconsistently.
dmar_writel() and dmar_writeq() swapped the order of the address and value
parameters, so I put those changes in a separate patch for ease of
reviewing. I'm happy to squash them if desired.
