Subject: [PATCH 8/8] zipl: fix segmentation fault in automenu array
Description: zipl: fix segmentation fault in automenu array
Symptom: Building an automenu with a large number of entries may
lead to a 'double free or corruption' error in zipl.
Problem: The array to store automenu items is to small.
Solution: Correct the calculation for automenu array size.
Reproduction: Use zipl and build an automenu with a large number of
entries in the zipl configuration file.
