This patch does following fixes: 1. Make HCR_* flags as unsigned long long constants Reason : By default, compiler assumes numeric constants as signed hence sign extending it when assigned to unsigned variable such as hcr_el2 (in VCPU context). This accidently sets HCR_ID and HCR_CD making entire guest memory non-cacheable. On real HW, this breaks Stage2 ttbl walks and also breaks VirtIO. 2. VTCR_EL2_ORGN0_WBWA and VTCR_EL2_IRGN0_WBWA macros.
