Subject: [PATCH v4 14/24] KVM: arm64: Support unaligned fixmap in the nVHE hyp
Date: Tue, 6 May 2025 17:48:10 +0100 [thread overview]
Message-ID: <20250506164820.515876-15-vdonnefort@google.com> (raw)
In-Reply-To: <20250506164820.515876-1-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.
