## Summary create_region() mapped up to ENTRIES_PER_PGT pages through one final level table, from whatever address the region started at. The text region starts one page after the reserved area, so a region that crossed the end of the table wrapped around and mapped its last pages over the first entries of the same table. In a program with more than about 2 MB of text, the reserved area became read-only and the kernel faulted in umm_initialize(). ## Impact RELEASE ## Testing CI -- This is an automated message from the Apache Git Service.
