Patch series "remove alloc_vm_area", v4. This series removes alloc_vm_area, which was left over from the big vmalloc interface rework. It is a rather arkane interface, basicaly the equivalent of get_vm_area + actually faulting in all PTEs in the allocated area. It was originally addeds for Xen (which isn't modular to start with), and then grew users in zsmalloc and i915 which seems to mostly qualify as abuses of the interface, especially for i915 as a random driver should not set up PTE bits directly. This patch (of 11): * Document that you can call vfree() on an address returned from vmap() * Remove the note about the minimum size -- the minimum size of a vmalloc allocation is one page * Add a Context: section * Fix capitalisation * Reword the prohibition on calling from NMI context to avoid a double negative Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Boris Ostrovsky <boris.ostrovsky@oracle.com> Cc: Juergen Gross <jgross@suse.com> Cc: Stefano Stabellini <sstabellini@kernel.org> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Matthew Auld <matthew.auld@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Minchan Kim <minchan@kernel.org> Cc: Matthew Wilcox <willy@infradead.org> Cc: Nitin Gupta <ngupta@vflare.org> Cc: Uladzislau Rezki (Sony) <urezki@gmail.com> Link: https://lkml.kernel.org/r/20201002122204.1534411-1-hch@lst.de Link: https://lkml.kernel.org/r/20201002122204.1534411-2-hch@lst.de Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

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.
