From 4ff4c745a16c4c151a71863420811e7f406c3ec2 Mon Sep 17 00:00:00 2001 From: Andrea Parri Date: Wed, 31 Jan 2024 15:49:35 +0100 Subject: locking: Introduce prepare_sync_core_cmd() Introduce an architecture function that architectures can use to set up ("prepare") SYNC_CORE commands. The function will be used by RISC-V to update its "deferred icache- flush" data structures (icache_stale_mask). Architectures defining prepare_sync_core_cmd() static inline need to select ARCH_HAS_PREPARE_SYNC_CORE_CMD.
