#     
#     Pull arm64 fixes from Catalin Marinas:
#     
#      - Limit the linear region to 51-bit when KVM is running in nVHE mode.
#     
#        Otherwise, depending on the placement of the ID map, kernel-VA to
#        hyp-VA translations may produce addresses that either conflict with
#        other HYP mappings or generate addresses outside of the 52-bit
#        addressable range.
#     
#      - Instruct kmemleak not to scan the memory reserved for kdump as this
#        range is removed from the kernel linear map and therefore not
#        accessible.
