Some LPAE systems may have phys_offset above the 4GB mark. Hence, we
need phys_offset to be a 64-bit integer.

Report an error if the crash kernel memory region is outside of the
boot-view memory range - this can happen with systems such as
Keystone 2.

ARM kernel can be compiled with CONFIG_VMSPLIT_1G, CONFIG_VMSPLIT_2G or
CONFIG_VMSPLIT_3G. This patch dynamically detects PAGE_OFFSET according
to _stext symbol from /proc/kallsyms.

Make use of struct memory_ranges and provide a global usablemem_rgns.
This is in preparation for adding device tree support.

Implement support for loading dump capture kernels for ARM architecture. ARM
doesn't need any backup memory regions so only elfcore header is allocated from
the top of the reserved memory region. Only zImages are supported.
The dump capture kernel needs to be loaded to physical address corresponding to
the memory region reserved with 'crashkernel=size@start' kernel command line
parameter.
