Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq)
so that a controller driver can allocate a fixed range of irq_descs and use
a simple calculation to translate back and forth between linux and hw irq
numbers. This is needed to use an irq_domain with many of the ARM interrupt
controller drivers that manage their own irq_desc allocations. Ultimately
the goal is to migrate those drivers to use the linear revmap, but doing it
this way allows each driver to be converted separately which makes the
migration path easier.

irq_domain/powerpc: eliminate irq_map; use irq_alloc_desc() instead
This patch drops the powerpc-specific irq_map table and replaces it with
directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating
and freeing irq_desc structures.
This patch is a preparation step for generalizing the powerpc-specific virq
infrastructure to become irq_domains.
As part of this change, the irq_big_lock is changed to a mutex from a raw
spinlock. There is no longer any need to use a spin lock since the irq_desc
allocation code is now responsible for the critical section of finding
an unused range of irq numbers.
The radix lookup table is also changed to store the irq_data pointer instead
of the irq_map entry since the irq_map is removed. This should end up being
functionally equivalent since only allocated irq_descs are ever added to the
radix tree.
v5: - Really don't ever allocate virq 0. The previous version could still
do it if hint == 0
- Respect irq_virq_count setting for NOMAP. Some NOMAP domains cannot
use virq values above irq_virq_count.
- Use numa_node_id() when allocating irq_descs. Ideally the API should
obtain that value from the caller, but that touches a lot of call sites
so will be deferred to a follow-on patch.
- Fix irq_find_mapping() to include irq numbers lower than
NUM_ISA_INTERRUPTS. With the switch to irq_alloc_desc*(), the lowest
possible allocated irq is now returned by arch_probe_nr_irqs().
v4: - Fix incorrect access to irq_data structure in debugfs code
- Don't ever allocate virq 0

irq_domain/powerpc: Use common irq_domain structure instead of irq_host
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.

irq_domain: Make irq_domain structure match powerpc's irq_host
Part of the series to unify the irq remapping mechanisms in the
kernel. A follow up patch will copy the powerpc implementation into
kernel/irq/irqdomain.c, which will be a lot easier if the structures
are identical.
Where they differ, I've chose to use the powerpc names since there is
a lot more code using those names.

This updates the sha512 fix so that it doesn't cause excessive stack
usage on i386. This is done by reverting to the original code, and
avoiding the W duplication by moving its initialisation into the loop.
As the underlying code is in fact the one that we have used for years,
I'm pushing this now instead of postponing to the next cycle.
