We should free the initrd reserved memblock in an aligned manner,
because the initrd reserves the memblock in an aligned manner
in arm64_memblock_init().
Otherwise there are some fragments in memblock_reserved regions
after free_initrd_mem(). e.g.:
/sys/kernel/debug/memblock # cat reserved
0: 0x0000000080080000..0x00000000817fafff
1: 0x0000000083400000..0x0000000083ffffff
2: 0x0000000090000000..0x000000009000407f
3: 0x00000000b0000000..0x00000000b000003f
4: 0x00000000b26184ea..0x00000000b2618fff
The fragments like the ranges from b0000000 to b000003f and
from b26184ea to b2618fff should be freed.
And we can do free_reserved_area() after memblock_free(),
as free_reserved_area() calls __free_pages(), once we've done
that it could be allocated somewhere else,
but memblock and iomem still say this is reserved memory.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
