From 310df7a9fe400f32cde8a7edf80daad12cd9cf02 Mon Sep 17 00:00:00 2001 From: Yao Zi Date: Tue, 22 Oct 2024 16:01:37 +0000 Subject: [PATCH] linux-user/riscv: Fix definition of RISCV_HWPROBE_EXT_ZVFHMIN Current definition yields a negative 32bits value, messing up hwprobe result when Zvfhmin extension presents. Replace it by using a 1ULL bit shift value as done in kernel upstream.
