Add a new entry in stats to for svm page faults. If CONFIG_DEBUG_FS is
enabled, the count can be viewed with per GT stat debugfs file.
This is similar to what is already in place for vma page faults.
Example output:
cat /sys/kernel/debug/dri/0/gt0/stats
svm_pagefault_count: 6
tlb_inval_count: 78
vma_pagefault_count: 0
vma_pagefault_kb: 0
v2: Fix build with CONFIG_DRM_GPUSVM disabled
v3: Update argument in kernel doc

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.
