From 0eb0bd21e8382d10be8108952a0bb819915e1e2d Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Tue, 17 Sep 2024 22:23:10 +0800 Subject: LoongArch: Remove STACK_FRAME_NON_STANDARD(do_syscall) For now, we can remove STACK_FRAME_NON_STANDARD(do_syscall) because there is no objtool warning "do_syscall+0x11c: return with modified stack frame", then there is handle_syscall() which is the previous frame of do_syscall() in the call trace when executing the command "echo l > /proc/sysrq-trigger".
