Baoquan He e5b1574a8c x86, crash: wrap crash dumping code into crash related ifdefs
[ Upstream commit a4eeb2176d89fdf2785851521577b94b31690a60 ]

Now crash codes under kernel/ folder has been split out from kexec
code, crash dumping can be separated from kexec reboot in config
items on x86 with some adjustments.

Here, also change some ifdefs or IS_ENABLED() check to more appropriate
ones, e,g
 - #ifdef CONFIG_KEXEC_CORE -> #ifdef CONFIG_CRASH_DUMP
 - (!IS_ENABLED(CONFIG_KEXEC_CORE)) - > (!IS_ENABLED(CONFIG_CRASH_RESERVE))

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.
