Merge series "regulator: unexport regulator_lock/unlock()" from Michał Mirosław <mirq-linux@rere.qmqm.pl>:

This removes regulator_lock/unlock() calls around
regulator_notifier_call_chain() as they are redundant - drivers
already have to guarantee regulator_dev's existence during the call.

This should make reasoing about the lock easier, as this was the only
use outside regulator core code.

The only client that needed recursive locking from the notifier chain
was drivers/usb/host/ohci-da8xx.c, which responds to over-current
notification by calling regulator_disable().

Michał Mirosław (3):
  regulator: don't require mutex for regulator_notifier_call_chain()
  regulator: remove locking around regulator_notifier_call_chain()

The BD718(37/47/50) regulator enable states can be controlled either by SW
or by PMIC internal state machine.

On some systems mixture of SW and HW state machine controlled regulators is
needed.

Specifically, some SoCs signal SUSPEND state change to PMIC via
STBY_REQ line. Now there are setups that expect certain regulators then to
be disabled (by PMIC state machine) while other regulators should stay
enabled (regardless of HW state => SW control required).

Add a new device-tree property "rohm,no-regulator-enable-control" which can
be used to leave regulator(s) under HW state machine control.

The BD718(37/47/50) regulator enable states can be controlled
either by SW or by PMIC internal state machine. The bd718x7
driver has not supported leaving the regulators under HW state
machine control (except for cases where this is required to
avoid boot-up problems due to critical regulators being turned
OFF at reset when SNVS used as reset state).

On some systems this is undesirable as there now are setups where
mixture of SW and HW state machine controlled regulators is needed.

 - A fix for CPU hotplug on pseries, where on large/loaded systems we
   may not wait long enough for the CPU to be offlined, leading to
   crashes.

 - Addition of a raw cputable entry for Power10, which is not required
   to boot, but is required to make our PMU setup work correctly in
   guests.

 - Three fixes for the recent changes on 32-bit Book3S to move modules
   into their own segment for strict RWX.

 - A fix for a recent change in our powernv PCI code that could lead to
   crashes.

 - A change to our perf interrupt accounting to avoid soft lockups when
   using some events, found by syzkaller.

 - A change in the way we handle power loss events from the hypervisor
   on pseries. We no longer immediately shut down if we're told we're
   running on a UPS.

 - A few other minor fixes.

Pull x86 fix from Thomas Gleixner:
 "A single fix for x86 which removes the RDPID usage from the paranoid
  entry path and unconditionally uses LSL to retrieve the CPU number.

  RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid
  expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values
  and restores them either when leaving the run loop, on preemption or
  when going out to user space. MSR_TSX_AUX is part of that lazy MSR
  set, so after writing the guest value and before the lazy restore any
  exception using the paranoid entry will read the guest value and use
  it as CPU number to retrieve the GSBASE value for the current CPU when
  FSGSBASE is enabled. As RDPID is only used in that particular entry
  path, there is no reason to burden VMENTER/EXIT with two extra MSR
  writes. Remove the RDPID optimization, which is not even backed by
  numbers from the paranoid entry path instead"

Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

When adding a new fd to an epoll, and that this new fd is an
epoll fd itself, we recursively scan the fds attached to it
to detect cycles, and add non-epool files to a "check list"
that gets subsequently parsed.

However, this check list isn't completely safe when deletions
can happen concurrently. To sidestep the issue, make sure that
a struct file placed on the check list sees its f_count increased,
ensuring that a concurrent deletion won't result in the file
disapearing from under our feet.

Currently the nexthop code will use an empty NHA_GROUP attribute, but it
requires at least 1 entry in order to function properly. Otherwise we
end up derefencing null or random pointers all over the place due to not
having any nh_grp_entry members allocated, nexthop code relies on having at
least the first member present. Empty NHA_GROUP doesn't make any sense so
just disallow it.
Also add a WARN_ON for any future users of nexthop_create_group().
