A problem is found by back porting page parallel initialisation for RHEL7.2.
And CONFIG_NO_BOOTMEM = n. If kernel old version with page parallel needs
to work well, it still needs to fix with BOOTMEM as this patch looks like.
There are some potential bugs with page parallel in RHEL7.2. I will cont

Parallel initialisation has been enabled for X86, boot time is
improved greatly. On Power8, it is improved greatly for small
memory. Here is the result from my test on Power8 platform:
For 4GB memory: 57% is improved, boot time as the following:
with patch: 10s, without patch

This patch is based on Mel Gorman's old patch in the mailing list,
https://lkml.org/lkml/2015/5/5/280 which is discussed but it is
fixed with a completion to wait for all memory initialised in
page_alloc_init_late(). It is to fix the OOM problem on X86
with 24TB memory

Uptream has supported page parallel initialisation for X86 and the
boot time is improved greately. Some tests have been done for Power.
Here is the result I have done with different memory size.
* 4GB memory:
boot time is as the following:
with patch vs without patch
