Add a method to find a region specified by reserve_mem=nn:align:name for ramoops. Adding a kernel command line parameter: reserve_mem=12M:4096:oops ramoops.mem_name=oops Will use the size and location defined by the memmap parameter where it finds the memory and labels it "oops". The "oops" in the ramoops option is used to search for it. This allows for arbitrary RAM to be used for ramoops if it is known that the memory is not cleared on kernel crashes or soft reboots.

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 reStructuredText 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.
