#     Merge branch 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull preemption Kconfig fix from Thomas Gleixner:
#      "The PREEMPT_RT stub config renamed PREEMPT to PREEMPT_LL and defined
#       PREEMPT outside of the menu and made it selectable by both PREEMPT_LL
#       and PREEMPT_RT.
#     
#       Stupid me missed that 114 defconfigs select CONFIG_PREEMPT which
#       obviously can't work anymore. oldconfig builds are affected as well,
#       but it's more obvious as the user gets asked. [old]defconfig silently
#       fixes it up and selects PREEMPT_NONE.
#     
#       Unbreak it by undoing the rename and adding a intermediate config
#       symbol which is selected by both PREEMPT and PREEMPT_RT. That requires
#       to chase down a few #ifdefs, but it's better than tweaking 114
#       defconfigs and annoying users"
