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.
