This patch adds huge page support to allow userspace to allocate huge
pages and to use hugetlbfs filesystem on 32- and 64-bit Linux kernels.
A later patch will add kernel support to map kernel text and data on
huge pages.
The only requirement is, that the kernel needs to be compiled for a
PA8X00 CPU (PA2.0 architecture). Older PA1.X CPUs do not support
variable page sizes. 64bit Kernels are compiled for PA2.0 by default.
Technically on parisc multiple physical huge pages may be needed to
emulate standard 2MB huge pages.

For the 64bit kernel the initially 16 MB kernel memory might become too
small if you build a kernel with many modules built-in and with kernel

This patch increases the initial mapping to 32MB for 64bit kernels and
keeps 16MB for 32bit kernels.

A fault vector on parisc needs to be 2K aligned. Furthermore the
checksum of the fault vector needs to sum up to 0 which is being
calculated and written at runtime.
Up to now we aligned both PA20 and PA11 fault vectors on the same 4K
page in order to easily write the checksum after having mapped the
kernel read-only (by mapping this page only as read-write).
But when we want to map the kernel text and data on huge pages this
makes things harder.
So, simplify it by aligning both fault vectors on 2K boundries and write
the checksum before we map the page read-only.

Huge pages on parisc will have the same size as one pmd table, which
is on a 64bit kernel 2MB on a kernel with 4K kernel page sizes, and
on a 32bit kernel 4MB when used with 4K kernel pages.
Since parisc does not physically supports 2MB huge page sizes, emulate
it with two consecutive 1MB page sizes instead. Keeping the same huge
page size as one pmd will allow us to add transparent huge page support
later on.
Bit 21 in the pte flags was unused and will now be used to mark a page
as huge page (_PAGE_HPAGE_BIT).

Returning zero from the measurment function has the side effect of
corrupting the triggered buffer readings, better to use -EINVAL than
a zero measurement reading.
The INVALID status happens even it isn't out of range
sometimes roughly once every second or two. This can be from an
invalid second signal return path. Hence there are spurious zero
readings from the triggered buffer, and warning messages in the kernel
log.

Starting with commit fd2bb310ca (Staging: iio: Move evgen interrupt
generation to irq_work) event processing is handled by calling
both the top half and the threaded part properly simulating real
hardware interrupts making use of threaded interrupts.
This way the processing is split in 2 parts:
* the IRQ handler that runs in IRQ context and only saves the event
timestamp
* the threaded handler that runs in process context, reads the events
and pushes the in the userspace.
If the IRQ handler returns IRQ_HANDLED the threaded handler is not
even being called since the interrupt is considered to be processed.
Because the iio dummy driver processes the events in the threaded
handler the IRQ handler must return IRQ_WAKE_THREAD so that the
threaded part would be awakened and called.

As we are now passing the filter data as pointers to the drivers,
we can take the final step and also pass the filter function the
same way. I'm keeping this change separate, as there it's less
obvious that this is a net win.
Upsides of this are:
- The ASoC drivers are completely independent from the DMA engine
implementation, which simplifies the Kconfig logic and in theory
allows the same sound drivers to be built in a kernel that supports
different kinds of dmaengine drivers.
- Consistency with other subsystems and drivers
On the other hand, we have a few downsides:
- The s3c24xx-dma driver now needs to be built-in for the ac97 platform
device to be instantiated on s3c2440.
- samsung_dmaengine_pcm_config cannot be marked 'const' any more
because the filter function pointer needs to be set at runtime.
This is safe as long we don't have multiple different DMA engines
in thet same system at runtime, but is nonetheless ugly.
