From: Jisheng Zhang Date: Thu, 12 Jan 2023 01:10:18 +0800 Subject: [PATCH v3 04/13] riscv: hwcap: make ISA extension ids can be used in asm In-Reply-To: <20230111171027.2392-1-jszhang@kernel.org> References: <20230111171027.2392-1-jszhang@kernel.org> Message-ID: <20230111171027.2392-5-jszhang@kernel.org> List-Id: To: kvm-riscv@lists.infradead.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit We will make use of ISA extension in asm files, so make the multi-letter RISC-V ISA extension IDs macros rather than enums and move them and those base ISA extension IDs to suitable place.
