Subject: Re: [PATCH v2 0/2] mm: Introduce kernelcore=reliable option

Sorry for the slow turnaround testing this.

This version seems to do better with my quirky system.
Summary of /proc/zoneinfo now looks like this:

$ ./zoneinfo
Node          Normal         Movable             DMA           DMA32
   0        17090.04        85687.43           14.93         1677.41
   1        17949.70        81490.98
   2        17911.66        85675.00
   3        17936.42        85313.32

which gets close to the mirror numbers reported in early part of boot:

[    0.000000] efi: Memory: 81050M/420096M mirrored memory

SUM(Normal) = 70887.82

There are ~8GB of "struct page" allocated from boot time allocator,
which covers most of the difference in the values.
