A mirror of the official Linux kernel repository just in case

The flags AS_UNMOVABLE and AS_INACCESSIBLE were both added just for guest_memfd; AS_UNMOVABLE is already in existing versions of Linux, while AS_INACCESSIBLE was acked for inclusion in 6.11. But really, they are the same thing: only guest_memfd uses them, at least for now, and guest_memfd pages are unmovable because they should not be accessed by the CPU. So merge them into one; use the AS_INACCESSIBLE name which is more comprehensive. At the same time, this fixes an embarrassing bug where AS_INACCESSIBLE was used as a bit mask, despite it being just a bit index. The bug was mostly benign, because AS_INACCESSIBLE's bit representation (1010) corresponded to setting AS_UNEVICTABLE (which is already set) and AS_ENOSPC (except no async writes can happen on the guest_memfd). So the AS_INACCESSIBLE flag simply had no effect. Fixes: |

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.
