77 	 * Cache operations:
78 	 *
79 	 * We define the following primitives:
80 	 *
81 	 *	icache_sync_all		Synchronize I-cache
82 	 *	icache_sync_range	Synchronize I-cache range
83 	 *
84 	 *	dcache_wbinv_all	Write-back and Invalidate D-cache
85 	 *	dcache_wbinv_range	Write-back and Invalidate D-cache range
86 	 *	dcache_inv_range	Invalidate D-cache range
87 	 *	dcache_wb_range		Write-back D-cache range
88 	 *
89 	 *	idcache_wbinv_all	Write-back and Invalidate D-cache,
90 	 *				Invalidate I-cache
91 	 *	idcache_wbinv_range	Write-back and Invalidate D-cache,
92 	 *				Invalidate I-cache range
93 	 *
94 	 * Note that the ARM term for "write-back" is "clean".  We use
95 	 * the term "write-back" since it's a more common way to describe
96 	 * the operation.
97 	 *
98 	 * There are some rules that must be followed:
99 	 *
100 	 *	I-cache Synch (all or range):
101 	 *		The goal is to synchronize the instruction stream,
102 	 *		so you may beed to write-back dirty D-cache blocks
103 	 *		first.  If a range is requested, and you can't
104 	 *		synchronize just a range, you have to hit the whole
105 	 *		thing.
106 	 *
107 	 *	D-cache Write-Back and Invalidate range:
108 	 *		If you can't WB-Inv a range, you must WB-Inv the
109 	 *		entire D-cache.
110 	 *
111 	 *	D-cache Invalidate:
112 	 *		If you can't Inv the D-cache, you must Write-Back
113 	 *		and Invalidate.  Code that uses this operation
114 	 *		MUST NOT assume that the D-cache will not be written
115 	 *		back to memory.
116 	 *
117 	 *	D-cache Write-Back:
118 	 *		If you can't Write-back without doing an Inv,
119 	 *		that's fine.  Then treat this as a WB-Inv.
120 	 *		Skipping the invalidate is merely an optimization.
121 	 *
122 	 *	All operations:
123 	 *		Valid virtual addresses must be passed to each
124 	 *		cache operation.
