genirq/matrix: Fix the precedence fix for real

The previous commit which made the operator precedence in
irq_matrix_available() explicit made the implicit brokenness explicitely
wrong. It was wrong in the original commit already. The overworked
maintainer did not notice it either when merging the patch.

Replace the confusing '?' construct by a simple and obvious if ().

Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq core updates from Thomas Gleixner:
"A rather large update for the interrupt core code and the irq chip drivers:

- Add a new bitmap matrix allocator and supporting changes, which is
used to replace the x86 vector allocator which comes with separate
pull request. This allows to replace the convoluted nested loop
allocation function in x86 with a facility which supports the
recently added property of managed interrupts proper and allows to
switch to a best effort vector reservation scheme, which addresses
problems with vector exhaustion.

- A large update to the ARM GIC-V3-ITS driver adding support for
range selectors.

- New interrupt controllers:
- Meson and Meson8 GPIO
- BCM7271 L2
- Socionext EXIU

If you expected that this will stop at some point, I have to
disappoint you. There are new ones posted already. Sigh!

- STM32 interrupt controller support for new platforms.

- A pile of fixes, cleanups and updates to the MIPS GIC driver

- The usual small fixes, cleanups and updates all over the place.
Most visible one is to move the irq chip drivers Kconfig switches
into a separate Kconfig menu"

genirq: Implement bitmap matrix allocator

Implement the infrastructure for a simple bitmap based allocator, which

architectures

genirq: Implement bitmap matrix allocator

Implement the infrastructure for a simple bitmap based allocator, which
will replace the x86 vector allocator. It's in the core code as other
architectures might be able to reuse/extend it. For now it only implements
allocations for single CPUs, but it's simple to add multi CPU allocation
support if required.

The concept is rather simple:

Global information:
system_vector bitmap
global accounting

PerCPU information:
allocation bitmap
managed allocation bitmap
local accounting

The system vector bitmap is used to exclude vectors system wide from the
allocation space.

The allocation bitmap is used to keep track of per cpu used vectors.

The managed allocation bitmap is used to reserve vectors for managed
interrupts.

When a regular (non managed) interrupt allocation happens then the
following rule applies:

tmpmap = system_map | alloc_map | managed_map
find_zero_bit(tmpmap)

Oring the bitmaps together gives the real available space. The same rule
applies for reserving a managed interrupt vector. But contrary to the
regular interrupts the reservation only marks the bit in the managed map
and therefor excludes it from the regular allocations. The managed map is
only cleaned out when the a managed interrupt is completely released and it
stays alive accross CPU offline/online operations.

For managed interrupt allocations the rule is:

tmpmap = managed_map & ~alloc_map
find_first_bit(tmpmap)

This returns the first bit which is in the managed map, but not yet
allocated in the allocation map. The allocation marks it in the allocation
map and hands it back to the caller for use.

The rest of the code are helper functions to handle the various
requirements and the accounting which are necessary to replace the x86
vector allocation code. The result is a single patch as the evolution of
this infrastructure cannot be represented in bits and pieces.
