Subject: target/riscv: Fix page_check_range use in fault-only-first
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4cc9f284d5971ecd8055d26ef74c23ef0be8b8f5;p=qemu.git

target/riscv: Fix page_check_range use in fault-only-first

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.
