staging: mfd: hi6421-spmi-pmic: get rid of interrupt properties

Both irqnum and irqarray properties reflect the same thing:
the number of bits and bytes for interrupts at this
chipset. E. g.:

irqnum = 8 x irqarray

This can be seen by the way pending interrupts are handled:

/* During probe time */
pmic->irqs = devm_kzalloc(dev, pmic->irqnum * sizeof(int), GFP_KERNEL);

/* While handling IRQs */
for (i = 0; i < pmic->irqarray; i++) {
pending = hi6421_spmi_pmic_read(pmic, (i + pmic->irq_addr));
pending &= 0xff;

for_each_set_bit(offset, &pending, 8)
generic_handle_irq(pmic->irqs[offset + i * 8]);

}

Going further, there are some logic at the driver which assumes
that irqarray is 2:

/* solve powerkey order */
if ((i == HISI_IRQ_KEY_NUM) &&
    ((pending & HISI_IRQ_KEY_VALUE) == HISI_IRQ_KEY_VALUE)) {
generic_handle_irq(pmic->irqs[HISI_IRQ_KEY_DOWN]);
generic_handle_irq(pmic->irqs[HISI_IRQ_KEY_UP]);
pending &= (~HISI_IRQ_KEY_VALUE);
}

As HISI_IRQ_KEY_DOWN and HISI_IRQ_KEY_UP are fixed values
and don't depend on irqnum/irqarray.

The IRQ addr and mask addr seem to be also fixed, based on some
comments at the OF parsing code. So, get rid of them too,
removing the of parsing function completely.

  General fixes too, and a lot of them marked for stable.

  Lastly, a bit of fallout from the async buffered reads, where we now
  more easily trigger short reads. Some applications don't really like
  that, so the io_read() code now handles short reads internally, and
  got a cleanup along the way so that it's now easier to read (and

Commit 1355c31eeb7e ("asm-generic: pgalloc: provide generic pmd_alloc_one()
and pmd_free_one()") converted parisc to use generic version of
pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for
PMD.

Restore the original version of pmd_alloc_one() for parisc, just use
GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and
memset.

io_uring: short circuit -EAGAIN for blocking read attempt

One case was missed in the short IO retry handling, and that's hitting
-EAGAIN on a blocking attempt read (eg from io-wq context). This is a
problem on sockets that are marked as non-blocking when created, they
don't carry any REQ_F_NOWAIT information to help us terminate them
instead of perpetually retrying.

io_uring: sanitize double poll handling

There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.

Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().

Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.
