Merge tag 'for-linus' of git://github.com/openrisc/linux

Pull OpenRISC updates from Stafford Horne:
"The OpenRISC work is a bit more interesting this time, adding SMP
support and a few general cleanups.

Small Things:

- Move OpenRISC docs into Documentation and clean them up

- Document previously undocumented devicetree bindings

- Update the or1ksim dts to use stdout-path

OpenRISC SMP support details:

- First the "use shadow registers" and "define CPU_BIG_ENDIAN as
true" get the architecture ready for SMP.

- The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
qrwlocks" add the SMP locking infrastructure as needed. Using the
qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
original spinlocks implementation.

- The "support for ompic" adds a new irqchip device which is used for
IPI communication to support SMP.

- The "initial SMP support" adds smp.c and makes changes to all of
the necessary data-structures to be per-cpu.

The remaining patches are bug fixes and debug helpers which I wanted
to keep separate from the "initial SMP support" in order to allow them
to be reviewed on their own. This includes:

- add cacheflush support to fix icache aliasing

- fix initial preempt state for secondary cpu tasks

- sleep instead of spin on secondary wait

- support framepointers and STACKTRACE_SUPPORT

- enable LOCKDEP_SUPPORT and irqflags tracing

- timer sync: Add tick timer sync logic

- fix possible deadlock in timer sync, pointed out by mips guys

Note: the irqchip patch was reviewed with Marc and we agreed to push
it together with these patches"

openrisc: initial SMP support

This patch introduces the SMP support for the OpenRISC architecture.
The SMP architecture requires cores which have multi-core features which
have been introduced a few years back including:

- New SPRS SPR_COREID SPR_NUMCORES
- Shadow SPRs
- Atomic Instructions
- Cache Coherency
- A wired in IPI controller

This patch adds all of the SMP specific changes to core infrastructure,
it looks big but it needs to go all together as its hard to split this
one up.

Boot loader spinning of second cpu is not supported yet, it's assumed
that Linux is booted straight after cpu reset.

The bulk of these changes are trivial changes to refactor to use per cpu
data structures throughout. The addition of the smp.c and changes in
time.c are the changes. Some specific notes:

MM changes
----------
The reason why this is created as an array, and not with DEFINE_PER_CPU
is that doing it this way, we'll save a load in the tlb-miss handler
(the load from __per_cpu_offset).

TLB Flush
---------
The SMP implementation of flush_tlb_* works by sending out a
function-call IPI to all the non-local cpus by using the generic
on_each_cpu() function.

Currently, all flush_tlb_* functions will result in a flush_tlb_all(),
which has always been the behaviour in the UP case.

CPU INFO
--------
This creates a per cpu cpuinfo struct and fills it out accordingly for
each activated cpu. show_cpuinfo is also updated to reflect new version
information in later versions of the spec.

SMP API
-------
This imitates the arm64 implementation by having a smp_cross_call
callback that can be set by set_smp_cross_call to initiate an IPI and a
handle_IPI function that is expected to be called from an IPI irqchip
driver.

dc91c728fd "xen: allow extra memory to be in multiple regions"
24aa07882b "memblock, x86: Replace memblock_x86_reserve/free..."

conflicted on xen_add_extra_mem() updates. The resolution is
trivial as the latter just want to replace
memblock_x86_reserve_range() with memblock_reserve().

* drivers/pci/intel-iommu.c

166e9278a3f "x86/ia64: intel-iommu: move to drivers/iommu/"
5dfe8660a3d "bootmem: Replace work_with_active_regions() with..."

conflicted as the former moved the file under drivers/iommu/.
Resolved by applying the chnages from the latter on the moved
file.

* mm/Kconfig

6661672053a "memblock: add NO_BOOTMEM config symbol"
c378ddd53f9 "memblock, x86: Make ARCH_DISCARD_MEMBLOCK a config option"

conflicted trivially. Both added config options. Just
letting both add their own options resolves the conflict.

* mm/memblock.c

d1f0ece6cdc "mm/memblock.c: small function definition fixes"
ed7b56a799c "memblock: Remove memblock_memory_can_coalesce()"

confliected. The former updates function removed by the
latter. Resolution is trivial.
