Subject: [PATCH 6/7] arm64: Stop calling page_address() in free_pages()
Date: Tue, 26 Aug 2025 12:32:57 -0700	[thread overview]
Message-ID: <20250826193258.902608-7-vishal.moola@gmail.com> (raw)
In-Reply-To: <20250826193258.902608-1-vishal.moola@gmail.com>

free_pages() should be used when we only have a virtual address. We
should call __free_pages() directly on our page instead.
