Commit in Fixes introduced early_reserve_memory() to do all needed
initial memblock_reserve() calls in one function. Unfortunately, the call
of early_reserve_memory() is done too late for Xen dom0, as in some
cases a Xen hook called by e820__memory_setup() will need those memory
reservations to have happened already.
Move the call of early_reserve_memory() before the call of
e820__memory_setup() in order to avoid such problems.
Fixes: a799c2bd29 ("x86/setup: Consolidate early memory reservations")

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.
