From: Xiong Zhang xiong.y.zhang@intel.com

commit b721b65af4eb46df6a1d9e34b14003225e403565 upstream.

For ADDR_4K_MASK, bit[45..12] should be 1, all other bits should be 0. The current definition wrongly set bit[46] as 1 also. This path fixes this.

v2: Add commit message, fixes and cc stable.(Zhenyu)
