* tag 'core_urgent_for_v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  rseq: Prevent hard lockup on granted time slice extension

The !CONFIG_NO_HZ_COMMON stubs use ktime_add(), ktime_get() and TICK_NSEC,
but tick.h includes neither <linux/ktime.h> nor <linux/jiffies.h>. Most
configurations build only because those declarations arrive transitively.

Commit 6440966067dc ("cpuset: Remove cpuset_cpu_is_isolated()") removed
<linux/cpuset.h> from <linux/sched/isolation.h>. The <linux/cpuset.h>
include chain had been satisfying these declarations before <linux/tick.h>
was parsed. Commit 8aa76aa41589 ("ring-buffer: Use a housekeeping CPU to
wake up waiters") then added <linux/sched/isolation.h> to ring_buffer.c
ahead of any header which provides them. Neither change is wrong on its
own: the failure requires both and appeared in v7.0.

ARM rpc_defconfig + CONFIG_FUNCTION_TRACER fails to build:

  $ make ARCH=arm rpc_defconfig
  $ ./scripts/config -e FTRACE -e FUNCTION_TRACER
  $ make ARCH=arm olddefconfig
  $ make ARCH=arm kernel/trace/ring_buffer.o
  In file included from include/linux/sched/isolation.h:6,
                   from kernel/trace/ring_buffer.c:8:

__exit_to_user_mode_loop() invokes rseq_grant_timeslice_extension() with
interrupts enabled. If the extension is granted it invokes
hrtimer_rearm_deferred_tif() to ensure that a pending deferred hrtimer
rearm is handled before exiting to user space.

Though this invokes __hrtimer_rearm_deferred() which expects to be invoked
with interrupts disabled as it takes hrtimer_cpu_base::lock with
raw_spin_lock(). That's a livelock waiting to happen and caught by lockdep:

    WARNING: ./include/linux/hrtimer_rearm.h:17 at irqentry_exit, CPU#1: slice_test
    WARNING: inconsistent lock state
    inconsistent {IN-HARDIRQ-W} -> {HARDIRQ-ON-W} usage.

Prevent this by disabling interrupts around the invocation of
hrtimer_rearm_deferred_tif() in rseq_grant_timeslice_extension().
