Merge tag 'lsm-pr-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull LSM updates from Paul Moore:

 - Rework the LSM initialization code

   What started as a "quick" patch to enable a notification event once
   all of the individual LSMs were initialized, snowballed a bit into a
   30+ patch patchset when everything was done. Most of the patches, and
   diffstat, is due to splitting out the initialization code into
   security/lsm_init.c and cleaning up some of the mess that was there.
   While not strictly necessary, it does cleanup the code signficantly,
   and hopefully makes the upkeep a bit easier in the future.

   Aside from the new LSM_STARTED_ALL notification, these changes also
   ensure that individual LSM initcalls are only called when the LSM is
   enabled at boot time. There should be a minor reduction in boot times
   for those who build multiple LSMs into their kernels, but only enable
   a subset at boot.

   It is worth mentioning that nothing at present makes use of the
   LSM_STARTED_ALL notification, but there is work in progress which is
   dependent upon LSM_STARTED_ALL.

 - Make better use of the seq_put*() helpers in device_cgroup
