On ARM it's relevant to not only distinguish between ordinary cached memory and write-combined one, but also having non-cached memory too. To insert the appropriated page table entries e.g.: in the base-hw kernel, we need to preserve the information about the kind of memory from allocation until the pager resolves a page fault. Therefore, this commit introduces a new Cache_attribute type, and replaces the write_combined boolean with the new type where necessary.
