Subject: [PATCH] target/riscv: Fix page_check_range use in fault-only-first
Date: Sat, 29 Jul 2023 11:16:18 +0800 [thread overview]
Message-ID: <20230729031618.821-1-zhiwei_liu@linux.alibaba.com> (raw)
Commit bef6f008b98(accel/tcg: Return bool from page_check_range) converts
integer return value to bool type. However, it wrongly converted the use
of the API in riscv fault-only-first, where page_check_range < = 0, should
be converted to !page_check_range.
