commit 02e2a5bfebe99edcf9d694575a75032d53fe1b73 upstream.
If md->signature == MAC_DRIVER_MAGIC and md->block_size == 1023, a single
512 byte sector would be read (secsize / 512). However the partition
structure would be located past the end of the buffer (secsize % 512).

block/partitions/mac.c: obey the state->limit constraint2013-02-28T03:10:21+00:00Ming Leiming.lei@canonical.com2013-02-28T01:05:18+00:00urn:sha1:06004e6eebdaf101a0f9b533fac77b5768d2c09c
It isn't necessary to read the information of partitions whose number is
equal and more than state->limit since only maximum state->limit
partitions will be added inside rescan_partitions().
That is also what other kind of partitions are doing.
