Pull tracing fixes from Steven Rostedt:
 "This adds three fixes for the tracing code.

  The first is a bug when ftrace_dump_on_oops is triggered in atomic
  context and function graph tracer is the tracer that is being
  reported.

  The second fix is bad parsing of the trace_events from the kernel
  command line, where it would ignore specific events if the system name
  is used with defining the event(it enables all events within the
  system).

  The last one is a fix to the TRACE_DEFINE_ENUM(), where a check was
  missing to see if the ptr was incremented to the end of the string,
  but the loop increments it again and can miss the nul delimiter to
  stop processing"

Currently an allyesconfig build [gcc-4.9.1] can generate the following:

   WARNING: vmlinux.o(.text.unlikely+0x3864): Section mismatch in
   reference from the function cpumask_empty.constprop.3() to the
   variable .init.data:nmi_ipi_mask

which comes from the cpumask_empty usage in arch/x86/kernel/nmi_selftest.c.

Normally we would not see a symbol entry for cpumask_empty since it is:

	static inline bool cpumask_empty(const struct cpumask *srcp)

however in this case, the variant of the symbol gets emitted when GCC does
constant propagation optimization.

Fix things up so that any locally optimized constprop variants don't warn
when accessing variables that live in the __init sections.

Currently the match() function supports a leading * to match any
prefix and a trailing * to match any suffix.  However there currently
is not a combination of both that can be used to target matches of
whole families of functions that share a common substring.

Here we expand the *foo and foo* match to also support *foo* with
the goal of targeting compiler generated symbol names that contain
strings like ".constprop." and ".isra."

As Guenter pointed out, we were never really calculating the extable entry
size because the pointer arithmetic was simply wrong.  We want to check
we're handling the second relocation in __ex_table to infer an entry size,
but we were using (void*) pointers instead of Elf_Rel[a]* ones.

This fixes the problem by moving that check in the caller (since we can
deal with different types of relocations) and add is_second_extable_reloc()
to make the whole thing more readable.

As Guenter pointed out, we want to assert that extable_entry_size has been
discovered and not the other way around.  Moreover, this sanity check is
only valid when we're not dealing with the first relocation in __ex_table,
since we have not discovered the extable entry size at that point.

This was leading to a divide-by-zero on some architectures and make the
build fail.

Merge "urgent omap boot fix for v4.1 if MFD_SYSCON is not set" from Tony
Lindgren:

Urgent pull request for v4.1 to booting for custom kernel
.config files that do not have MFD_SYSCON set.

Omaps now have a dependency to MFD_SYSCON for system control
module generic register area and some clocks with the changes
done in omap-for-v4.1/prcm-dts branch.

This can be pulled on top of omap-for-v4.1/prcm-dts, or into
fixes for v4.1.

We already do have a slight MFD_SYSCON dependency for
REGULATOR_PBIAS for dual voltage MMC cards on the first MMC
bus for many devices, so from that point of view this can
also be merged separately from omap-for-v4.1/prcm-dts.

Prior to c770cb4c ("PCI: Mark invalid BARs as unassigned"), if we tried
to claim a PCI BAR but could not find an upstream bridge window that
matched it, we complained but still allowed the device to be enabled.

c770cb4c broke devices that previously worked (mptsas and igb in the
case Tony reported, but it could be any devices) because it marks those
BARs as IORESOURCE_UNSET, which makes pci_enable_device() complain and
return failure:

  igb 0000:81:00.0: can't enable device: BAR 0 [mem size 0x00020000] not assigned
  igb: probe of 0000:81:00.0 failed with error -22

The underlying cause is an ACPI Address Space Descriptor for a PCI host
bridge window that is marked as "consumer".  This is a firmware defect:
resources that are produced on the downstream side of a bridge should be
marked "producer".  But rejecting these BARs that we previously allowed is
a functionality regression, and firmware has not used the producer/consumer
bit consistently, so we can't rely on it anyway.

Stop checking the producer/consumer bit, and assume all bridge Address
Space Descriptors are for bridge windows.

Note that this change does not affect I/O Port or Fixed Location I/O Port
Descriptors, which are commonly used for the [io 0x0cf8-0x0cff] config
access range.  That range is a "consumer" range and should not be treated
as a window.
