[Makedumpfile Patch v3 0/7] Fix --mem-usage /proc/kcore

[Pratyush Anand]

`makedumpfile --mem-usage /proc/kcore` has been broken after kaslr specific
modifications. Kernel commit commit 464920104bf7 (/proc/kcore: update
physical address for kcore ram and text) provides now valid physical
address for direct mapped regions and invalid (-1) for other areas.  This
helps to fix the issue in makedumpfile for both the case of kaslr enabled
and disabled.

Changes since v2:
 - Fixed a memory leak issue and updated man page and usage info
Changes since v1:
 - One more patch..Now mem-usage with older kernel (< 4.11) will only work
   when that has been rightly patched and -f has been used in makedumpfile
   command line.


Baoquan He (2):
  makedumpfile: Correct the calculation of kvaddr in
    set_kcore_vmcoreinfo
  makedumpfile: Discard process_dump_load

Pratyush Anand (5):
  show_mem_usage(): calculate page offset after elf load
  initial(): call cach_init() a bit early
  x86_64: check physical address in PT_LOAD for none direct mapped
    regions
  elf_info: kcore: check for invalid physical address
  mem-usage: allow to work only with -f for kernel version < 4.11
