When using LPAE the call to alloc_init_pte is passed then end address for the entire 1st level page table region, and the code unluckily ends up going over the bounds of the single allocated PTE, which is sad. This caused LPAE boot on omap5 to crash. There may be some hidden mystery in the boot code that I'm unaware of or it may be assumed that all mappings are always mappable as sections on LPAE and therefore omap5 just does something bad, in which case this patch isn't the right fix, but I'd be happy to be told the reason.

I was about to reply on the LPAE boot issue you mentioned in other email. We have seen couple of issues with LPAE on OMAP5 and sent the fixes. [1] ARM: LPAE: Fix alloc_init_section to flush all the pmd entries [2] ARM: LPAE: Fix mapping in alloc_init_pte for unaligned addresses Both needs ack from Catalin and RMK's ok to get into the patch system. Can you please check if they work for you ? I expect the [1] should make your board boot on OMAP5.
