#     x86/ldt: use "pr_info_once()" instead of open-coding it badly
#     
#     Using a mutex for "print this warning only once" is so overdesigned as
#     to be actively offensive to my sensitive stomach.
#     
#     Just use "pr_info_once()" that already does this, although in a
#     (harmlessly) racy manner that can in theory cause the message to be
#     printed twice if more than one CPU races on that "is this the first
#     time" test.
#     
#     [ If somebody really cares about that harmless data race (which sounds
#       very unlikely indeed), that person can trivially fix printk_once() by
#       using a simple atomic access, preferably with an optimistic non-atomic
#       test first before even bothering to treat the pointless "make sure it
#       is _really_ just once" case.
#     
#       A mutex is most definitely never the right primitive to use for
#       something like this. ]
#     
#     Yes, this is a small and meaningless detail in a code path that hardly
#     matters.  But let's keep some code quality standards here, and not
#     accept outrageously bad code.
