  arm64: kdump: Skip kmemleak scan reserved memory for kdump (2021-09-10 11:58:59 +0100)

----------------------------------------------------------------
arm64 fixes:

- 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.
