From: Anup Patel Date: Wed, 26 Jan 2022 17:14:46 +0530 Subject: [PATCH v10 2/8] RISC-V: Rename relocate() and make it global In-Reply-To: <20220126114452.692512-1-apatel@ventanamicro.com> References: <20220126114452.692512-1-apatel@ventanamicro.com> Message-ID: <20220126114452.692512-3-apatel@ventanamicro.com> List-Id: To: kvm-riscv@lists.infradead.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit From: Anup Patel The low-level relocate() function enables mmu and relocates execution to link-time addresses. We rename relocate() function to relocate_enable_mmu() function which is more informative. Also, the relocate_enable_mmu() function will be used in the resume path when a CPU wakes-up from a non-retentive suspend so we make it global symbol.
