It appears arm64 copied arm's GENERIC_IRQ_MULTI_HANDLER code, but made
it unconditional.

Converts the arm64 code to use the new generic code, which simply consists
of deleting the arm64 code and setting MULTI_IRQ_HANDLER instead.

Converts the ARM interrupt code to use the recently added
GENERIC_IRQ_MULTI_HANDLER, which is essentially just a copy of ARM's
existhing MULTI_IRQ_HANDLER.  The only changes are:

* handle_arch_irq is now defined in a generic C file instead of an
  arm-specific assembly file.
 
* handle_arch_irq is now marked as __ro_after_init.

GENERIC_IRQ_MULTI_HANDLER is incompatible with MULTI_IRQ_HANDLER because
they define the same symbols.  Multiple generic irqchip drivers select
MULTI_IRQ_HANDLER, which is now defined on all architectures that
provide set_handle_irq().

To solve this select GENERIC_IRQ_MULTI_HANDLER for all drivers that used to
select MULTI_IRQ_HANDLER, but only when MULTI_IRQ_HANDLER doesn't exist.

After that every architecture can be converted over from MULTI_IRQ_HANDLER
to GENERIC_IRQ_MULTI_HANDLER before removing the extra MULTI_IRQ_HANDLER
scaffolding.

When pciehp is converted to threaded IRQ handling, removal of unplugged
devices below a PCIe hotplug port happens synchronously in the IRQ thread.
Removal of devices typically entails a call to free_irq() by their drivers.

If those devices share their IRQ with the hotplug port, __free_irq()
deadlocks because it calls synchronize_irq() to wait for all hard IRQ
handlers as well as all threads sharing the IRQ to finish.

Actually it's sufficient to wait only for the IRQ thread of the removed
device, so call synchronize_hardirq() to wait for all hard IRQ handlers to
finish, but no longer for any threads.  Compensate by rearranging the
control flow in irq_wait_for_interrupt() such that the device's thread is
allowed to run one last time after kthread_stop() has been called.

kthread_stop() blocks until the IRQ thread has completed.  On completion
the IRQ thread clears its oneshot thread_mask bit.  This is safe because
__free_irq() holds the request_mutex, thereby preventing __setup_irq() from
handing out the same oneshot thread_mask bit to a newly requested action.

Previously a race existed between __free_irq() and __setup_irq() wherein
the thread_mask of a just removed action could be handed out to a newly
added action and the freed irq thread would then tread on the oneshot
mask bit of the newly added irq thread in irq_finalize_oneshot():

time
 |  __free_irq()
 |    raw_spin_lock_irqsave(&desc->lock, flags);
 |    <remove action from linked list>
 |    raw_spin_unlock_irqrestore(&desc->lock, flags);
 |
 |  __setup_irq()
 |    raw_spin_lock_irqsave(&desc->lock, flags);
 |    <traverse linked list to determine oneshot mask bit>
 |    raw_spin_unlock_irqrestore(&desc->lock, flags);
 |
 |  irq_thread() of freed irq (__free_irq() waits in synchronize_irq())
 |    irq_thread_fn()
 |      irq_finalize_oneshot()
 |        raw_spin_lock_irq(&desc->lock);
 |        desc->threads_oneshot &= ~action->thread_mask;
 |        raw_spin_unlock_irq(&desc->lock);
 v

The race was known at least since 2012 when it was documented in a code
comment by commit e04268b0 ("genirq: Remove paranoid warnons and bogus
fixups"). The race itself is harmless as nothing touches any of the
potentially freed data after synchronize_irq().

In 2017 the race was close by commit 9114014c ("genirq: Add mutex to
irq desc to serialize request/free_irq()"), apparently inadvertantly so
because the race is neither mentioned in the commit message nor was the
code comment updated.  Make up for that.

Since commit 425a5072 ("genirq: Free irq_desc with rcu"),
show_interrupts() can be switched to rcu locking, which removes possible
contention on sparse_irq_lock.

The per_cpu count scan and print can be done without holding desc spinlock.

And there is no need to call kstat_irqs_cpu() and abuse irq_to_desc() while
holding rcu read lock, since desc and desc->kstat_irqs wont disappear or
change.

Pull RISC-V updates from Palmer Dabbelt:
 "This contains some small RISC-V updates I'd like to target for 4.18.

  They are all fairly small this time. Here's a short summary, there's
  more info in the commits/merges:

   - a fix to __clear_user to respect the passed arguments.

   - enough support for the perf subsystem to work with RISC-V's ISA
     defined performance counters.

   - support for sparse and cleanups suggested by it.

   - support for R_RISCV_32 (a relocation, not the 32-bit ISA).

   - some MAINTAINERS cleanups.

   - the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's
     always present.

  I've given these a simple build+boot test"
