Pull tracing fixes from Steven Rostedt:
 "This fixes two annoying bugs:

   - The first one is a side effect caused by using SRCU for rcuidle
     tracepoints. It seems that the perf was depending on the rcuidle
     tracepoints to make RCU watch when it wasn't.

     The real fix will be to have perf use SRCU instead of depending on
     RCU watching, but that can't be done until SRCU is safe to use in
     NMI context (Paul's working on that).

   - The second bug fix is for a bug that's been periodically making my
     tests fail randomly for some time. I haven't had time to track it
     down, but finally have. It has to do with stressing NMIs (via perf)
     while enabling or disabling ftrace function handling with lockdep
     enabled.

     If an interrupt happens and just as it returns, it sets lockdep
     back to "interrupts enabled" but before it returns an NMI is
     triggered, and if this happens while printk_nmi_enter has a
     breakpoint attached to it (because ftrace is converting it to or
     from nop to call fentry), the breakpoint trap also calls into
     lockdep, and since returning from the NMI to a interrupt handler,
     interrupts were disabled when the NMI went off, lockdep keeps its
     state as interrupts disabled when it returns back from the
     interrupt handler where interrupts are enabled.

     This causes lockdep_assert_irqs_enabled() to trigger a false
     positive"

---[ end trace b7c64aa79e17954a ]---

After a bit of debugging, I found what was happening. This would trigger
when performing "perf" with a high NMI interrupt rate, while enabling and
disabling function tracer. Ftrace uses breakpoints to convert the nops at
the start of functions to calls to the function trampolines. The breakpoint
traps disable interrupts and this makes calls into lockdep via the
trace_hardirqs_off_thunk in the entry.S code. What happens is the following:

  do_idle {

    [interrupts enabled]

    <interrupt> [interrupts disabled]
	TRACE_IRQS_OFF [lockdep says irqs off]
	[...]
	TRACE_IRQS_IRET
	    test if pt_regs say return to interrupts enabled [yes]
	    TRACE_IRQS_ON [lockdep says irqs are on]

	    <nmi>
		nmi_enter() {
		    printk_nmi_enter() [traced by ftrace]
		    [ hit ftrace breakpoint ]
		    <breakpoint exception>
			TRACE_IRQS_OFF [lockdep says irqs off]
			[...]
			TRACE_IRQS_IRET [return from breakpoint]
			   test if pt_regs say interrupts enabled [no]
			   [iret back to interrupt]
	   [iret back to code]

    tick_nohz_idle_enter() {

	lockdep_assert_irqs_enabled() [lockdep say no!]

Although interrupts are indeed enabled, lockdep thinks it is not, and since
we now do asserts via lockdep, it gives a false warning. The issue here is
that printk_nmi_enter() is called before lockdep_off(), which disables
lockdep (for this reason) in NMIs. By simply not allowing ftrace to see
printk_nmi_enter() (via notrace annotation) we keep lockdep from getting
confused.

This is due to the tracepoints moving to SRCU usage which does not require
RCU to be "watching". But perf uses these tracepoints with RCU and expects
it to be. Hence, we still need to add in the rcu_irq_enter/exit_irqson()
calls for "rcuidle" tracepoints. This is a temporary fix until we have SRCU
working in NMI context, and then perf can be converted to use that instead
of normal RCU.

Using a static const struct definition as part of a series of
declarations produces a false positive "Missing a blank line after
declarations" for code like:

  WARNING: Missing a blank line after declarations
  #710: FILE: drivers/gpu/drm/tidss/tidss_scale_coefs.c:137:
  +       int inc;
  +       static const struct {

So fix it.

When getting rid of the general ipc_lock(), this was missed furthermore,
making the comment around the ipc object validity check bogus.  Under
EIDRM conditions, callers will in turn not see the error and continue
with the operation.

When scanning for movable pages, filter out Hugetlb pages if hugepage
migration is not supported.  Without this we hit infinte loop in
__offline_pages() where we do

	pfn = scan_movable_pages(start_pfn, end_pfn);
	if (pfn) { /* We have movable pages */
		ret = do_migrate_range(pfn, end_pfn);
		goto repeat;
	}

Fix this by checking hugepage_migration_supported both in
has_unmovable_pages which is the primary backoff mechanism for page
offlining and for consistency reasons also into scan_movable_pages
because it doesn't make any sense to return a pfn to non-migrateable
huge page.

This issue was revealed by, but not caused by 72b39cfc ("mm,
memory_hotplug: do not fail offlining too early").

Currently we get the following compiler warning:

       if (s->object_size < min_objsize)

due to the mismatch of signed/unsigned comparison.  ->object_size and

unsigned int.

If kmemleak built in to the kernel, but is disabled by default, the
debugfs file is never registered.  Because of this, it is not possible
to find out if the kernel is built with kmemleak support by checking for
the presence of this file.  To allow this, always register the file.

After this patch, if the file doesn't exist, kmemleak is not available
in the kernel.  If writing "scan" or any other value than "clear" to
this file results in EBUSY, then kmemleak is available but is disabled
by default and can be activated via the kernel command line.

Catalin: "that's also consistent with a late disabling of kmemleak when
the debugfs entry sticks around."

Commit d70f2a14 ("include/linux/sched/mm.h: uninline mmdrop_async(),
etc") ignored the return value of arch_dup_mmap(). As a result, on x86,
a failure to duplicate the LDT (e.g. due to memory allocation error)
would leave the duplicated memory mapping in an inconsistent state.

Fix by using the return value, as it was before the change.

Commit 93065ac7 ("mm, oom: distinguish blockable mode for mmu
notifiers") has added an ability to skip over vmas with blockable mmu
notifiers. This however didn't call tlb_finish_mmu as it should.

As a result inc_tlb_flush_pending has been called without its pairing
dec_tlb_flush_pending and all callers mm_tlb_flush_pending would flush
even though this is not really needed.  This alone is not harmful and it
seems there shouldn't be any such callers for oom victims at all but
there is no real reason to skip tlb_finish_mmu on early skip either so
call it.

When the memcg OOM killer runs out of killable tasks, it currently
prints a WARN with no further OOM context.  This has caused some user
confusion.

Warnings indicate a kernel problem.  In a reported case, however, the
situation was triggered by a nonsensical memcg configuration (hard limit
set to 0).  But without any VM context this wasn't obvious from the
report, and it took some back and forth on the mailing list to identify
what is actually a trivial issue.

Handle this OOM condition like we handle it in the global OOM killer:
dump the full OOM context and tell the user we ran out of tasks.

This way the user can identify misconfigurations easily by themselves
and rectify the problem - without having to go through the hassle of
running into an obscure but unsettling warning, finding the appropriate
kernel mailing list and waiting for a kernel developer to remote-analyze
that the memcg configuration caused this.

If users cannot make sense of why the OOM killer was triggered or why it
failed, they will still report it to the mailing list, we know that from
experience.  So in case there is an actual kernel bug causing this,
kernel developers will very likely hear about it.

Recent refactoring of add_metainfo() caused use_all_metadata() to add
metainfo to ife action metalist without taking reference to module. This
causes warning in module_put called from ife action cleanup function.

Implement add_metainfo_and_get_ops() function that returns with reference
to module taken if metainfo was added successfully, and call it from
use_all_metadata(), instead of calling __add_metainfo() directly.

Immediately after module_put(), user could delete this
module, so e->ops could be already freed before we call
e->ops->release().

Fix this by moving module_put() after ops->release().

Correct the formula for calculating the RQ page remainder,
which should be in byte granularity.  The result will be
non-zero only for RQs smaller than PAGE_SIZE, as an RQ size
is a power of 2.

Divide this by the SQ stride (MLX5_SEND_WQE_BB) to get the
SQ offset in strides granularity.

syzbot reports a divide-by-zero off the NBD_SET_BLKSIZE ioctl.
We need proper validation of the input here. Not just if it's
zero, but also if the value is a power-of-2 and in a valid
range. Add that.
