Pull locking updates from Ingo Molnar:
"Here are the locking changes in this cycle:
- rwsem unification and simpler micro-optimizations to prepare for
more intrusive (and more lucrative) scalability improvements in
v5.3 (Waiman Long)
- Lockdep irq state tracking flag usage cleanups (Frederic
Weisbecker)
- static key improvements (Jakub Kicinski, Peter Zijlstra)
- misc updates, cleanups and smaller fixes"
* 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (26 commits)

locking/static_key: Add support for deferred static branches
locking/lockdep: Test all incompatible scenarios at once in check_irq_usage()
locking/lockdep: Avoid bogus Clang warning
locking/lockdep: Generate LOCKF_ bit composites
locking/lockdep: Use expanded masks on find_usage_*() functions
locking/lockdep: Map remaining magic numbers to lock usage mask names
locking/lockdep: Move valid_state() inside CONFIG_TRACE_IRQFLAGS && CONFIG_PROVE_LOCKING
locking/rwsem: Prevent unneeded warning during locking selftest
locking/rwsem: Optimize rwsem structure for uncontended lock acquisition
locking/rwsem: Enable lock event counting
locking/lock_events: Don't show pvqspinlock events on bare metal

Unicore processors can not fetch/store information which is not
|
|
naturally aligned on the bus, i.e., a 4 byte fetch must start at an
|
|
address divisible by 4. On 32-bit Unicore processors, these non-aligned
|
|
fetch/store instructions will be emulated in software if you say
|
|
here, which has a severe performance impact. This is necessary for
|
|
correct operation of some network protocols. With an IP-only
|
|
configuration it is safe to say N, otherwise say Y.

Always use the default kernel command string, even if the boot
|
|
loader passes other arguments to the kernel.
|
|
This is useful if you cannot or don't want to change the
|
|
command-line options your boot loader passes to the kernel.
|
|
|
|
If unsure, say N.
