Pull more parisc updates from Helge Deller:

 - During this merge window O_NONBLOCK was changed to become 000200000,
   but we missed that the syscalls timerfd_create(), signalfd4(),
   eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict
   bit-wise check of the flags parameter.

   To provide backward compatibility with existing userspace we
   introduce parisc specific wrappers for those syscalls which filter
   out the old O_NONBLOCK value and replaces it with the new one.

 - Prevent HIL bus driver to get stuck when keyboard or mouse isn't
   attached

 - Improve error return codes when setting rtc time

 - Minor documentation fix in pata_ns87415.c

When starting a HP machine with HIL driver but without an HIL keyboard
or HIL mouse attached, it may happen that data written to the HIL loop
gets stuck (e.g. because the transaction queue is full).  Usually one
will then have to reboot the machine because all you see is and endless
output of:
 Transaction add failed: transaction already queued?

In the higher layers hp_sdc_enqueue_transaction() is called to queued up
a HIL packet. This function returns an error code, and this patch adds
the necessary checks for this return code and disables the HIL driver if
further packets can't be sent.

Tested on a HP 730 and a HP 715/64 machine.

 "A couple more driver quirks, now enabling newer trackpoints from
  Synaptics for real"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: i8042 - add nopnp quirk for Acer Aspire 5 A515
  Input: trackpoint - enable Synaptics trackpoints

Touchpad on this laptop is not detected properly during boot, as PNP
enumerates (wrongly) AUX port as disabled on this machine.

Fix that by adding this board (with admittedly quite funny DMI
identifiers) to nopnp quirk list.

For a Hyper-V vmbus, the size of the ringbuffer has two requirements:

1) it has to take one PAGE_SIZE for the header

2) it has to be PAGE_SIZE aligned so that double-mapping can work

VMBUS_RING_SIZE() could calculate a correct ringbuffer size which
fulfills both requirements, therefore use it to make sure vmbus work
when PAGE_SIZE != HV_HYP_PAGE_SIZE (4K).

Note that since the argument for VMBUS_RING_SIZE() is the size of
payload (data part), so it will be minus 4k (the size of header when
PAGE_SIZE = 4k) than the original value to keep the ringbuffer total
size unchanged when PAGE_SIZE = 4k.

platform_get_irq() returns -ERRNO on error.  In such case comparison
