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.

When we specify a large number for node in hugepages parameter, it may be parsed to another number due to truncation in this statement: node = tmp; For example, add following parameter in command line: hugepagesz=1G hugepages=4294967297:5 and kernel will allocate 5 hugepages for node 1 instead of ignoring it. I move the validation check earlier to fix this issue, and slightly simplifies the condition here.
