[PATCH 0/4 V3] Support kdump for AMD secure memory encryption(SME)

2018-06-16 Thread Lianbo Jiang
It is convenient to remap the old memory encrypted to the second kernel by calling ioremap_encrypted(). When sme enabled on AMD server, we also need to support kdump. Because the memory is encrypted in the first kernel, we will remap the old memory encrypted to the second kernel(crash kernel), and
