Subject: [PATCH V2 13/30] mm/mmap: Drop arch_vm_get_page_pgprot()
Date: Mon, 21 Feb 2022 12:08:22 +0530 [thread overview]
Message-ID: <1645425519-9034-14-git-send-email-anshuman.khandual@arm.com> (raw)
In-Reply-To: <1645425519-9034-1-git-send-email-anshuman.khandual@arm.com>
There are no platforms left which use arch_vm_get_page_prot(). Just drop
arch_vm_get_page_prot() construct and simplify remaining code.
