Achilleas Anagnostopoulos	dbdf686d27	Provide helper for setting the active frame allocator ... This allows us to remove the allocFn argument from the vmm functions which causes the compiler's escape analysis to sometimes incorectly flag it as escaping to the heap.	2017-06-18 09:49:47 +01:00
Achilleas Anagnostopoulos	c0a9e07e83	Remove mem.PageOrder ... Since the goal is to bootstrap the runtime's slab-like allocator the kernel should only deal with managing allocations at a single page level.	2017-06-18 09:14:53 +01:00
Achilleas Anagnostopoulos	76532089c5	Define PageDirectoryTable and helpers that support inactive tables ... The Map/Unmap methods of PageDirectoryTable operate similar to the global Map/Unmap functions. While the global functions work with the currently active PDT, the PageDirectoryTable methods can also work with inactive page tables by temporarily modifying the recursive mapping of the active PDT to point to the inactive PDT frame before delegating the mapping/unmapping to the global Map/Unmap functions.	2017-06-06 19:35:07 +01:00
