From 307094c9e26ef704d7061733f8d6fab9ca2ad09a Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Sat, 25 Jan 2025 18:51:43 +0800 Subject: [PATCH] LoongArch: Adjust SETUP_SLEEP and SETUP_WAKEUP SETUP_SLEEP should only save the GPR context, which is symmetric to SETUP_WAKEUP, so move the acpi_saved_sp handling out of SETUP_SLEEP. Move "addi.d sp, sp, PT_SIZE" into SETUP_WAKEUP for the same reason. No functional changes.
