Souptick Joarder 0edf681375 drivers/gpu/drm/gma500/: change return type to vm_fault_t
Use new return type vm_fault_t for fault handler.  For now, this is just
documenting that the function returns a VM_FAULT value rather than an
errno.  Once all instances are converted, vm_fault_t will become a
distinct type.

Ref-> 1c8f422059 ("mm: change return type to vm_fault_t")

Previously vm_insert_{pfn,mixed} returns err which driver mapped into
VM_FAULT_* type.  The new function vmf_insert_{pfn,mixed} will replace
this inefficiency by returning VM_FAULT_* type.

vmf_error() is the newly introduce inline function in 4.17-rc6.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
