Subject: exec: Fix cpu_watchpoint_address_matches address length
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9835936d4450dccd5e6fabd3c34330420036b028;p=qemu.git

exec: Fix cpu_watchpoint_address_matches address length

The only caller of cpu_watchpoint_address_matches passes
TARGET_PAGE_SIZE, so the bug is not currently visible.
