[Jan Kiszka <jan.kiszka@domain.hid>]

The following changes since commit 113ea4d56e8b215cb56ae7673013163ea5a5987d:
  Gilles Chanteperdrix (1):

This is the first of likely three rounds of patches for 2.5.x. It mostly
deals with introducing rtdm_rt_capable to replace the
__xn_exec_conforming marks of RTDM syscalls and with deprecating RT
open/socket/close for RTDM devices. The latter affects quite a few
devices in our tree, so I'm CC'ing the maintainers to check if they see
any problems in dropping RT creation/closure at this point.

Besides some smaller fixes and an irqbench refactoring, this series also
contains a solution for the confusions about incompatible rttest<n>
devices. It simply avoids collisions be using different device names for
the different device subclasses.

Please review and merge if no concerns remain.

BTW, the other two rounds I mentioned will deal with /proc overflow
fixes and avoiding RTDM context polling on close (I still need to finish
my unit test, therefore this delay). Those should follow over the
weekend.
