[PATCH v4 0/11] kexec: Add option to get crash kernel region size

[Eric DeVolder]

This is the fourth version of a patch series originally posted by
Daniel Kiper on December 5.

This version differs from the previous version based on feedback
received from the mailing list, as such:

v4: Incorporated feedback:
    - additional changes for coding convention and formatting
v3: Incorporated feedback:
    - changes for coding convention and formatting
    - restructured to introduce get_crash_kernel_load_range() for each
      architecture, and then a single function in kexec/kexec.c to call
      the per-architecture get_crash_kernel_load_range() and print the
      result.
v2: Incorporated feedback:
    - utilize the is_crashkernel_mem_reserved() function common in all archs
    - for ppc and ppc64, utilize device-tree values to print size
    - for unsupported architectures, print appropriate message
v1: Posted to kexec-tools mailing list
