This patchset adds support for ARMv8.2 extensions in makedumpfile code. I cover the following two cases with this patchset: - 48-bit VA + 52-bit PA (LPA) - 48-bit kernel VA + 52-bit virtual VA (LVA) This has been tested for the following user-cases: 1. Calculating --mem-usage on the primary kernel, 2. Creating a dumpfile using /proc/vmcore, and 3. Post-processing a vmcore. I have tested this patchset on the following platforms, with kernels which support/do-not-support ARMv8.2 features: 1. CPUs which don't support ARMv8.2 features, e.g. qualcomm-amberwing, ampere-osprey. 2. ARMv8 FVP model, which supports ARMv8.2 extensions.
