Subject: [PATCH v7 19/28] KVM: arm64: Support unaligned fixmap in the pKVM hyp
Date: Fri, 3 Oct 2025 14:38:16 +0100 [thread overview]
Message-ID: <20251003133825.2068970-20-vdonnefort@google.com> (raw)
In-Reply-To: <20251003133825.2068970-1-vdonnefort@google.com>
Return the fixmap VA with the page offset, instead of the page base
address. This allows to use hyp_fixmap_map() seamlessly regardless of
the address alignment.
