With nouveau fixed all ttm-using drives have the correct nesting of mmap_sem vs dma_resv, and we can just lock the buffer. Assuming I didn't screw up anything with my audit of course. v2: - Dont forget wu_mutex (Christian König) - Keep the mmap_sem-less wait optimization (Thomas) - Use _lock_interruptible to be good citizens (Thomas) v3: Rebase over fault handler helperification.

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.
