Pull x86 kdump update from Ingo Molnar:
"This includes two changes:
- Raise the crash kernel reservation limit from from ~896MB to ~4GB.
Only very old (and already known-broken) kexec-tools is supposed to
be affected by this negatively.
- Allow higher than 4GB crash kernel allocations when low allocations
fail"
* 'x86-kdump-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/kdump: Fall back to reserve high crashkernel memory
x86/kdump: Have crashkernel=X reserve under 4G by default
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.
