[PATCH v3] arm64: Add support for PTE contiguous bit.

2015-11-19 Thread David Woods
The arm64 MMU supports a Contiguous bit which is a hint that the TTE is one of a set of contiguous entries which can be cached in a single TLB entry. Supporting this bit adds new intermediate huge page sizes. The set of huge page sizes available depends on the base page size. Without using contig
