Subject: [PULL 11/46] linux-user: Move get_elf_hwcap to mips/elfload.c
Date: Thu, 28 Aug 2025 09:19:48 +1000	[thread overview]
Message-ID: <20250827232023.50398-12-richard.henderson@linaro.org> (raw)
In-Reply-To: <20250827232023.50398-1-richard.henderson@linaro.org>

Change the return type to abi_ulong, and pass in the cpu.
