[Stable-9.1.2 15/58] linux-user/riscv: Fix definition of RISCV_HWPROBE_E


From: Michael Tokarev
Subject: [Stable-9.1.2 15/58] linux-user/riscv: Fix definition of RISCV_HWPROBE_EXT_ZVFHMIN
Date: Sat, 9 Nov 2024 15:08:16 +0300

From: Yao Zi <ziyao@disroot.org>

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.
