Baoquan He 4b68a773a7 mm/vmalloc.c: optimize to reduce arguments of alloc_vmap_area()
If called by __get_vm_area_node(), by open coding the field assignments of
'struct vm_struct *vm', and move the vm->flags and vm->caller assignments
into __get_vm_area_node(), the passed in arguments 'flags' and 'caller'
can be removed.

This alleviates overloaded arguments passed in for alloc_vmap_area().

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.
