Dan reports that Anjaneya Chagam can no longer use the efi=nosoftreserve
kernel command line parameter to suppress "soft reservation" behavior.
This is due to the fact that the following call-chain happens at boot:
early_reserve_memory
|-> efi_memblock_x86_reserve_range
|-> efi_fake_memmap_early
which does
if (!efi_soft_reserve_enabled())
return;
and that would have set EFI_MEM_NO_SOFT_RESERVE after having parsed
"nosoftreserve".
However, parse_early_param() gets called *after* it, leading to the boot
cmdline not being taken into account.
Therefore, carve out the command line preparation into a separate
function which does the early param parsing too. So that it all goes
together.
And then call that function before early_reserve_memory() so that the
params would have been parsed by then.

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.
