Subject: devcgroup: always show positive major/minor num
From: Li Zefan <lizf@xxxxxxxxxxxxxx>
# echo "b $((0x7fffffff)):$((0x80000000)) rwm" > devices.allow
# cat devices.list
b 214748364:-21474836 rwm
though a major/minor number of 0x800000000 is meaningless, we
should not cast it to a negative value.
