zsmalloc: add Kconfig for enabling page table method
Zsmalloc has two methods 1) copy-based and 2) pte based to
access objects that span two pages.
You can see history why we supported two approach from [1].
But it was bad choice that adding hard coding to select arch
which want to use pte based method because there are lots of
SoC in an architecure and they can have different cache size,
CPU speed and so on so it would be better to expose it to user
as selectable Kconfig option like Andrew Morton suggested.

This dio subdevice (*insn_bits) function does not follow the "norm"
for comedi drivers. It also _appears_ to return the incorrect state
of the channels.
Use the comedi_dio_update_state() helper to handle the boilerplate
for updating the output channel state. Due to the hardware we then
need to invert the state and mask the input channels before updating
the outputs.
Then read the hardware and invert the result to get the current true
state of the dio channels.

Currently only the pcmuio_handle_asic_interrupt() function uses the
spinlock in the private data to protect the read of the paged interrupt
id registers. All accesses to the paged registers should be protected
to ensure that the page is not changed until the access is complete.
Move the lock/unlock into the pcmuio_{write,read}() functions to make
sure the access completes correctly. Rename the spinlock to variable

Legacy (ISA) interrupts are not sharable so this driver should not
be passing the IRQF_SHARED flag when requesting the interrupts.
This driver supports two board types:
PCM-UIO48 with one asic (one interrupt source)
PCM-UIO96 with two asics (two interrupt sources)
The PCM-UIO96 has a jumper that allows the two interrupt sources to
share an interrupt. This is safe for legacy interrupts as long as
the "shared" interrupt is handled by a single driver.
Modify the request_irq() code in this driver to correctly request the
interrupts. For the PCM-UI048 case (one asic) only one request_irq()
is needed. For the PCM-UIO96 (two asics) there are three cases:
1) irq is shared, one request_irq() call
2) only one asic has an irq, one request_irq() call
3) two irqs, two request_irq() calls
The irq for the first asic (dev->irq) will be requested during the
attach if required. The comedi core will handle the freeing of this
irq during the detach.
The irq for the second asic (devpriv->irq2) will also be requested
during the attach if required. The freeing of this irq will be
handled by the driver during the detach.
Move the board reset and interrupt request code so it occurs early
in the attach. We can then check dev->irq and devpriv->irq2 to see
if the subdevice command support actually needs to be initialized.
This also simplifies the interrupt handler. The irq can be simply
checked against dev->irq and devpriv->irq2 to see which asic caused
the interrupt.
Add a call to pcmuio_reset() in the (*detach) to make sure the
interrupts are disabled before freeing the irqs.
