Subject: [PATCH 04/12] riscv: mm: init: Pass a pointer to virt_to_page()
Date: Thu, 11 May 2023 13:59:21 +0200 [thread overview]
Message-ID: <20230503-virt-to-pfn-v6-4-rc1-v1-4-6c4698dcf9c8@linaro.org> (raw)
In-Reply-To: <20230503-virt-to-pfn-v6-4-rc1-v1-0-6c4698dcf9c8@linaro.org>
Functions that work on a pointer to virtual memory such as
virt_to_pfn() and users of that function such as
virt_to_page() are supposed to pass a pointer to virtual
memory, ideally a (void *) or other pointer. However since
many architectures implement virt_to_pfn() as a macro,
this function becomes polymorphic and accepts both a
(unsigned long) and a (void *).
Fix this in the RISCV mm init code, so we can implement
a strongly typed virt_to_pfn().
