Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU updates from Ingo Molnar:
"The sole purpose of these changes is to shrink and simplify the RCU
code base, which has suffered from creeping bloat over the past couple
of years. The end result is a net removal of ~2700 lines of code:
79 files changed, 1496 insertions(+), 4211 deletions(-)
Plus there's a marked reduction in the Kconfig space complexity as
well, here's the number of matches on 'grep RCU' in the .config:
before after
x86-defconfig 17 15
x86-allmodconfig 33 20"
