Subject: [PATCH v2 4/7] riscv: Stop calling page_address() in free_pages()
Date: Tue, 26 Aug 2025 13:56:14 -0700	[thread overview]
Message-ID: <20250826205617.1032945-5-vishal.moola@gmail.com> (raw)
In-Reply-To: <20250826205617.1032945-1-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.
