This patch series makes some enhancement to ITS configuration in the
following aspects:
o allocation of the ITS tables
o replacing magic numbers with sensible macros
o guarantees a safe quiescent status before initializing an ITS
o judging enabling status of LPI feature
This patch series is
When required DT size is out of the kmalloc()'s capability, the whole
ITS will fail in probing. This actually is not the hardware's problem
and is mainly a limitation of the kernel memory allocator. This patch
will keep ITS going on to the next initializaion step with an explicit
warning.
Define macros for GITS_CTLR fields to avoid using magic numbers.

Some kind of brain-dead implementations chooses to insert ITEes in
rapid sequence of disabled ITEes, and an un-zeroed ITT will confuse
ITS on judging whether an ITE is really enabled or not. Considering

There is one more condition that needs to be considered when judging
whether LPI feature is enabled or not, which is whether there is any
ITS available and correctly enabled.
This patch will fix this by caching ITS enabling status in the GIC

This patch separate ring information from struct xen_blkif to an new struct
xen_blkif_ring to make preparation for real multi hardware queues supporting.

The max number of hardware queues for xen/blkfront is num_online_cpus() or set
by module parameter, while the number xen/blkback supported is notified through
xenstore(multi-queue-max-queues).
The negotiated number was the smaller one, and was written back to
xen/blkback as multi-queue-num-queues.
Prepare patch for multi hardware queues, the ring number was mandatory set to 1.

Move the request complete logic out of blkif_interrupt() to a work queue,
after that we can replace 'spin_lock_irq' with 'spin_lock' so that irq won't
be disabled too long in blk_mq_queue_rq().
No more warning like this:

The STM32 MCUs family IP can be reset by accessing some shared registers.
The specificity is that some reset lines are used by the timers.
At timer initialization time, the timer has to be reset, that's why
we cannot use a regular driver.
