Pull m68knommu updates from Greg Ungerer:
"These changes all relate to converting the IO access functions for the
ColdFire (and all other non-MMU m68k) platforms to use asm-generic IO
instead.
This makes the IO support the same on all ColdFire (regardless of MMU
enabled or not) and means we can now support PCI in non-MMU mode.
As a bonus these changes remove more code than they add"

Commit 6870c0165f ("scripts/faddr2line: show the code context")
radically altered the output format of the faddr2line tool. And while
the new list output format might have merit it broke my vim usage and
was hard to read.
Make the new format optional; using a '--list' argument and attempt to
make the output slightly easier to read by adding a little whitespace to
separate the different files and explicitly mark the line in question.

mempool_init()/bioset_init() require that the mempools/biosets be zeroed
first; they probably should not _require_ this, but not allocating those
structs with kzalloc is a fairly nonsensical thing to do (calling
mempool_exit()/bioset_exit() on an uninitialized mempool/bioset is legal
and safe, but only works if said memory was zeroed.)

Pull x86 RAS updates from Thomas Gleixner:

- Avoid IPIs during CPU hotplug to read the MCx_MISC block address from

local.

Pull irq updates from Thomas Gleixner:
- Consolidation of softirq pending:
The softirq mask and its accessors/mutators have many implementations
scattered around many architectures. Most do the same things
consisting in a field in a per-cpu struct (often irq_cpustat_t)
accessed through per-cpu ops. We can provide instead a generic
efficient version that most of them can use. In fact s390 is the only
exception because the field is stored in lowcore.
- Support for level!?! triggered MSI (ARM)
Over the past couple of years, we've seen some SoCs coming up with
ways of signalling level interrupts using a new flavor of MSIs, where
the MSI controller uses two distinct messages: one that raises a
virtual line, and one that lowers it. The target MSI controller is in
charge of maintaining the state of the line.
This allows for a much simplified HW signal routing (no need to have
hundreds of discrete lines to signal level interrupts if you already
have a memory bus), but results in a departure from the current idea
the kernel has of MSIs.
