monitor: Prevent sign-extension of 32-bit addresses printed by info mem
Previously, on 32-bit i386, info mem used signed 32-bit int's to store the page table indexes. As a result, address calculation was done in 32 bits and then incorrectly sign-extended to 64 bits, yielding output like ffffffffef000000-ffffffffef031000 0000000000031000 ur- ffffffffef7bc000-ffffffffef7bd000 0000000000001000 urw ffffffffef7bd000-ffffffffef7be000 0000000000001000 ur- This makes these indexes unsigned, which yields correct output 00000000ef000000-00000000ef031000 0000000000031000 ur- 00000000ef7bc000-00000000ef7bd000 0000000000001000 urw 00000000ef7bd000-00000000ef7be000 0000000000001000 ur- Signed-off-by: Austin Clements <amdragon@mit.edu> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
