Subject: [PATCH] LoongArch: Fix SYM_SIGFUNC_START definition for 32BIT
Date: Wed, 29 Apr 2026 16:06:44 +0800 [thread overview]
Message-ID: <20260429080644.2425166-1-chenhuacai@loongson.cn> (raw)
The SYM_SIGFUNC_START definition should match sigcontext that the length
of GPRs are 8 bytes for both 32BIT and 64BIT. So replace SZREG with 8 to
fix it.
Cc: stable@vger.kernel.org
Fixes: e4878c37f6679fde ("LoongArch: vDSO: Emit GNU_EH_FRAME correctly")
