There was a report of NULL pointer dereference in ETF enable
path for perf CS mode with PID monitoring. It is almost 100%
reproducible when the process to monitor is something very
active such as chrome and with ETF as the sink, not ETR.

But code path shows that ETB has a similar path as ETF, so
there could be possible NULL pointer dereference crash in
ETB as well. Currently in a bid to find the pid, the owner
is dereferenced via task_pid_nr() call in etb_enable_perf()
and with owner being NULL, we can get a NULL pointer
dereference, so have a similar fix as ETF where we cache PID
in alloc_buffer() callback which is called as the part of
etm_setup_aux().

There was a report of NULL pointer dereference in ETF enable
path for perf CS mode with PID monitoring. It is almost 100%
reproducible when the process to monitor is something very
active such as chrome and with ETF as the sink and not ETR.
Currently in a bid to find the pid, the owner is dereferenced
via task_pid_nr() call in tmc_enable_etf_sink_perf() and with
owner being NULL, we get a NULL pointer dereference.

Looking at the ETR and other places in the kernel, ETF and the
ETB are the only places trying to dereference the task(owner)
in tmc_enable_etf_sink_perf() which is also called from the
sched_in path as in the call trace. Owner(task) is NULL even
in the case of ETR in tmc_enable_etr_sink_perf(), but since we
cache the PID in alloc_buffer() callback and it is done as part
of etm_setup_aux() when allocating buffer for ETR sink, we never
dereference this NULL pointer and we are safe. So lets do the
same thing with ETF and cache the PID to which the cs_buffer
belongs in tmc_alloc_etf_buffer() as done for ETR. This will
also remove the unnecessary function calls(task_pid_nr()) since
we are caching the PID.

Easily reproducible running below:

     fast wakeup path for asymmetric CPU capacity systems to align with
     the symmetric case. This ensures more locality and prevents massive
     migration overhead on those asymetric systems

     handing a modified buffer pointer to kfree()"

Pull locking fixes from Thomas Gleixner:
 "Two fixes for the locking subsystem:

   - Prevent an unconditional interrupt enable in a futex helper
     function which can be called from contexts which expect interrupts
     to stay disabled across the call

   - Don't modify lockdep chain keys in the validation process as that
     causes chain inconsistency"

  lockdep: Avoid to modify chain keys in validate_chain()
  futex: Don't enable IRQs unconditionally in put_pi_state()

Pull percpu fix and cleanup from Dennis Zhou:
 "A fix for a Wshadow warning in the asm-generic percpu macros came in
  and then I tacked on the removal of flexible array initializers in the
  percpu allocator"

* 'for-5.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu:
  percpu: convert flexible array initializers to use struct_size()
  asm-generic: percpu: avoid Wshadow warning

In some cases where shadow paging is in use, the root page will
be either mmu->pae_root or vcpu->arch.mmu->lm_root.  Then it will
not have an associated struct kvm_mmu_page, because it is allocated
with alloc_page instead of kvm_mmu_alloc_page.

Just return false quickly from is_tdp_mmu_root if the TDP MMU is
not in use, which also includes the case where shadow paging is
enabled.
