powerpc: Add NMI IPI infrastructure
Add a simple NMI IPI system that handles concurrency and reentrancy.
The platform does not have to implement a true non-maskable interrupt, the default is to simply use the debugger break IPI message. This has now been co-opted for a general IPI message, and users (debugger and crash) have been reimplemented on top of the NMI system.

NO_IRQ has been == 0 on powerpc for just over ten years (since commit 0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change platforms to use it")).
powerpc: Remove all usages of NO_IRQ
NO_IRQ has been == 0 on powerpc for just over ten years (since commit 0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change platforms to use it")). It's also 0 on most other arches.
Although it's fairly harmless, every now and then it causes confusion when a driver is built on powerpc and another arch which doesn't define NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least some of which are to work around that problem.
So we'd like to remove it. This is fairly trivial in the arch code, we just convert:
if (irq == NO_IRQ) to if (!irq) if (irq != NO_IRQ) to if (irq) irq = NO_IRQ; to irq = 0; return NO_IRQ; to return 0;
And a few other odd cases as well.
At least for now we keep the #define NO_IRQ, because there is driver code that uses NO_IRQ and the fixes to remove those will go via other trees.
Note we also change some occurrences in PPC sound drivers, drivers/ps3, and drivers/macintosh.

genirq/irqdomain: Allow irq domain aliasing
It is not uncommon (at least with the ARM stuff) to have a piece of hardware that implements different flavours of "interrupts". A typical example of this is the GICv3 ITS, which implements standard PCI/MSI support, but also some form of "generic MSI".
So far, the PCI/MSI domain is registered using the ITS device_node, so that irq_find_host can return it. On the contrary, the raw MSI domain is not registered with an device_node, making it impossible to be looked up by another subsystem (obviously, using the same device_node twice would only result in confusion, as it is not defined which one irq_find_host would return).
A solution to this is to "type" domains that may be aliasing, and to be able to lookup an device_node that matches a given type. For this, we introduce irq_find_matching_host() as a superset of irq_find_host:
struct irq_domain *irq_find_matching_host(struct device_node *node, enum irq_domain_bus_token bus_token);
where bus_token is the "type" we want to match the domain against (so far, only DOMAIN_BUS_ANY is defined). This result in some moderately invasive changes on the PPC side (which is the only user of the .match method).
This has otherwise no functionnal change.

We need the per-cpu address of struct cpu_iic, not cpu_iic.regs->prio.
Sparse noticed this, because we pass a non-iomem pointer to out_be64(), but we obviously don't check the sparse results often enough.

powerpc: Replace __get_cpu_var uses
This still has not been merged and now powerpc is the only arch that does not have this change. Sorry about missing linuxppc-dev before.
V2->V2 - Fix up to work against 3.18-rc1
__get_cpu_var() is used for multiple purposes in the kernel source. One of them is address calculation via the form &__get_cpu_var(x). This calculates the address for the instance of the percpu variable of the current processor based on an offset.
Other use cases are for storing and retrieving data from the current processors percpu area. __get_cpu_var() can be used as an lvalue when writing data or on the right side of an assignment.
__get_cpu_var() is defined as :
__get_cpu_var() always only does an address determination. However, store and retrieve operations could use a segment prefix (or global register on other platforms) to avoid the address calculation.
this_cpu_write() and this_cpu_read() can directly take an offset into a percpu area and use optimized assembly code to read and write per cpu variables.
This patch converts __get_cpu_var into either an explicit address calculation using this_cpu_ptr() or into a use of this_cpu operations that use the offset. Thereby address calculations are avoided and less registers are used when code is generated.
At the end of the patch set all uses of __get_cpu_var have been removed so the macro is removed too.
The patch set includes passes over all arches as well. Once these operations are used throughout then specialized macros can be defined in non -x86 arches as well in order to optimize per cpu access by f.e. using a global register that may be set to the per cpu base.
Transformations done to __get_cpu_var()
1. Determine the address of the percpu instance of the current processor.
DEFINE_PER_CPU(int, y); int *x = &__get_cpu_var(y);
Converts to
int *x = this_cpu_ptr(&y);
2. Same as #1 but this time an array structure is involved.
DEFINE_PER_CPU(int, y[20]); int *x = __get_cpu_var(y);
Converts to
int *x = this_cpu_ptr(y);
3. Retrieve the content of the current processors instance of a per cpu variable.
DEFINE_PER_CPU(int, y); int x = __get_cpu_var(y)
Converts to
int x = __this_cpu_read(y);
4. Retrieve the content of a percpu struct
DEFINE_PER_CPU(struct mystruct, y); struct mystruct x = __get_cpu_var(y);
Converts to
memcpy(&x, this_cpu_ptr(&y), sizeof(x));
5. Assignment to a per cpu variable
DEFINE_PER_CPU(int, y) __get_cpu_var(y) = x;
Converts to
__this_cpu_write(y, x);
6. Increment/Decrement etc of a per cpu variable

powerpc: Implement tick broadcast IPI as a fixed IPI message
For scalability and performance reasons, we want the tick broadcast IPIs to be handled as efficiently as possible. Fixed IPI messages are one of the most efficient mechanisms available - they are faster than the smp_call_function mechanism because the IPI handlers are fixed and hence they don't involve costly operations such as adding IPI handlers to the target CPU's function queue, acquiring locks for synchronization etc.
Luckily we have an unused IPI message slot, so use that to implement tick broadcast IPIs efficiently.

This patch also adds a host_data argument to the generators. There are cases where the host_data pointer will be needed before the function returns. ie. the legacy map calls the .map callback for each irq before returning.

This patch drops the powerpc-specific irq_host structures and uses the common irq_domain strucutres defined in linux/irqdomain.h. It also fixes all the users to use the new structure names.
Renaming irq_host to irq_domain has been discussed for a long time, and this patch is a step in the process of generalizing the powerpc virq code to be usable by all architecture.
An astute reader will notice that this patch actually removes the irq_host structure instead of renaming it. This is because the irq_domain structure already exists in include/linux/irqdomain.h and has the needed data members.

powerpc: various straight conversions from module.h --> export.h
All these files were including module.h just for the basic EXPORT_SYMBOL infrastructure. We can shift them off to the export.h header which is a way smaller footprint and thus realize some compile time gains.

powerpc/cell: Rename ipi functions to match current abstractions
Rename functions and arguments to reflect current usage. iic_cause_ipi becomes iic_message_pass and iic_ipi_to_irq becomes iic_msg_t
powerpc/cell: Rename ipi functions to match current abstractions
Rename functions and arguments to reflect current usage. iic_cause_ipi becomes iic_message_pass and iic_ipi_to_irq becomes iic_msg_to_irq, and iic_request_ipi now takes a message (msg) instead of an ipi number. Also mesg is renamed to msg.
Commit f1072939b6 (powerpc: Remove checks for MSG_ALL and MSG_ALL_BUT_SELF) connected the smp_message_pass hook for cell to the underlying iic_cause_IPI, a platform unique name. Later 23d72bfd8f (powerpc: Consolidate ipi message mux and demux) added a cause_ipi hook to the smp_ops, also used in message passing, but for controllers that can not send 4 unique messages and require multiplexing. It is even more confusing that the both take two arguments, but one is the small message ordinal and the other is an opaque long data associated with the cpu.
Since cell iic maps messages one to one to ipi irqs, rename the function and argument to translate from ipi to message. Also make it clear that iic_request_ipi takes a message number as the argument for which ipi to create and request.
No functionional change, just renames to avoid future confusion.
