	enable_mtrr_cleanup [X86]

			The kernel tries to adjust MTRR layout from continuous

			to discrete, to make X server driver able to add WB

			entry later. This parameter enables/disables that.



	mtrr_chunk_size=nn[KMG] [X86]

			used for mtrr cleanup. It is largest continous chunk

			that could hold holes aka. UC entries.



	mtrr_gran_size=nn[KMG] [X86]

			Used for mtrr cleanup. It is granularity of mtrr block.

			Default is 1.

			Large value could prevent small alignment from

			using up MTRRs.



	mtrr_spare_reg_nr=n [X86]

			Format: <integer>

			Range: 0,7 : spare reg number

			Default : 1

			Used for mtrr cleanup. It is spare mtrr entries number.
