#     Merge branch 'rcu/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu
#     
#     Pull RCU fix from Paul McKenney:
#      "This is a fix for a regression in the v5.10 merge window, but it was
#       reported quite late in the v5.10 process, plus generating and testing
#       the fix took some time.
#     
#       The regression is due to commit 36dadef23fcc ("kprobes: Init kprobes
#       in early_initcall") which on powerpc can use RCU Tasks before
#       initialization, resulting in boot failures.
#     
#       The fix is straightforward, simply moving initialization of RCU Tasks
#       before the early_initcall()s. The fix has been exposed to -next and
#       kbuild test robot testing, and has been tested by the PowerPC guys"
