Subject: [patch 122/200] arch, mm: make kernel_page_present() always available
Date: Mon, 14 Dec 2020 19:10:35 -0800 [thread overview]
Message-ID: <20201215031035.JFrXPelpJ%akpm@linux-foundation.org> (raw)
In-Reply-To: <20201214190237.a17b70ae14f129e2dca3d204@linux-foundation.org>
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: arch, mm: make kernel_page_present() always available
For architectures that enable ARCH_HAS_SET_MEMORY having the ability to
verify that a page is mapped in the kernel direct map can be useful
regardless of hibernation.
Add RISC-V implementation of kernel_page_present(), update its forward
declarations and stubs to be a part of set_memory API and remove ugly
ifdefery in inlcude/linux/mm.h around current declarations of
kernel_page_present().
