[PATCH v3 0/2] util/userfaultfd: Support /dev/userfaultfd |

To Juan: from what I observe on how to update the linux headers, I think it
can simply be in a pull just like a normal patch.
The most recent change and its pull for reference:
https://lore.kernel.org/all/20220915091035.3897-1-chenyi.qiang@intel.com/
https://lore.kernel.org/all/20220926170804.453855-1-thuth@redhat.com/
Changelog:
v3:
- Remove __linux__ macro check in util/userfaultfd.c [Juan]
- Avoid using globals, merge functions [Juan]
v2:
- Added R-bs for Phil
- Move open_mode into uffd_detect_open_mode() [Phil]
- Document uffd_open() in the header file [Phil]
- [Discussed with Daniel/Michal, decided to leave fd support for later]
The new /dev/userfaultfd handle is superior to the system call with a
better permission control and also works for a restricted seccomp
environment.
The new device was only introduced in v6.1 so we need a header update.
Please have a look, thanks.
