If anyone has any objections, please let me know. ------------------ From: Ralf Baechle commit d7de413475f443957a0c1d256e405d19b3a2cb22 upstream. TASK_SIZE was defined as 0x7fff8000UL which for 64k pages is not a multiple of the page size. Somewhere further down the math fails such that executing an ELF binary fails.
