 *	TLB Management

 *
 *	The TLB specific code is expected to perform whatever tests it
 *	needs to determine if it should invalidate the TLB for each
 *	call.  Start addresses are inclusive and end addresses are
 *	exclusive; it is safe to round these addresses down.
 *
 *	flush_tlb_all()
 *
 *		Invalidate the entire TLB.
 *
 *	flush_tlb_mm(mm)
 *
 *		Invalidate all TLB entries in a particular address
 *		space.
 *		- mm	- mm_struct describing address space
 *
 *	flush_tlb_range(mm,start,end)
 *
 *		Invalidate a range of TLB entries in the specified
 *		address space.
 *		- mm	- mm_struct describing address space
 *		- start - start address (may not be aligned)
 *		- end	- end address (exclusive, may not be aligned)
 *
 *	flush_tlb_page(vaddr,vma)
 *
 *		Invalidate the specified page in the specified address range.
 *		- vaddr - virtual address (may not be aligned)
 *		- vma	- vma_struct describing address range
 *
 *	flush_kern_tlb_page(kaddr)
 *
 *		Invalidate the TLB entry for the specified page.  The address
 *		will be in the kernels virtual memory space.  Current uses
 *		only require the D-TLB to be invalidated.

/*
 * We optimise the code below by:
 *  - building a set of TLB flags that might be set in __cpu_tlb_flags
 *  - building a set of TLB flags that will always be set in __cpu_tlb_flags
 *  - if we're going to need __cpu_tlb_flags, access it once and only once
 *
 * This allows us to build optimal assembly for the single-CPU type case,
 * and as close to optimal given the compiler constrants for multi-CPU
 * case.  We could do better for the multi-CPU case if the compiler
 * implemented the "%?" method, but this has been discontinued due to too
 * many people getting it wrong.
