* Fix the platform data support for the at91 adc driver.
* A couple of related follow up patches get the support working again
for at91sam9260 and at91sam9g45 as the earlier patch results in a device
name change.
* A default timer value in the at91 adc driver was bonkers. Make it sane.
* Fix incorrect reporting of the integration time for the cm32181 light sensor
* Fix a missing break in the ad2s1200 driver which would have give a false
error return.
* Make sure buffer scan mask queries from userspace return 0/1 rather than
a fairly random value depending on their implementation of test_bit
* Fix leak of the i2c client and a null pointer dereference in the cm36651
driver.
* Fix a build warning on avr32 for the mxs-lradc (not exactly a critical
combination - but the issue was real).

Fix e26a9e00af 'ARM: Better
virt_to_page() handling' replaced __pv_phys_offset with
__pv_phys_pfn_offset. Also note that size of __pv_phys_offset
was quad but size of __pv_phys_pfn_offset is word. Instruction
that used to update __pv_phys_offset which address is in r6
had to update low word of __pv_phys_offset so it used #LOW_OFFSET
macro for store offset. Now when size of __pv_phys_pfn_offset is
word, no difference between little endian and big endian should
exist - i.e no offset should be used when __pv_phys_pfn_offset
is stored.
Note that for little endian image proposed change is noop,
since in little endian case #LOW_OFFSET is defined 0 anyway.

The switcher should not depend on MAX_CLUSTER to determine ifit should
be activated or not. In a multiplatform kernel binary it is possible to
have dual-cluster and quad-cluster platforms configured in. In that case
MAX_CLUSTER which is a build time limit should be 4 and that shouldn't
prevent the switcher from working if the kernel is booted on a b.L
dual-cluster system.
In bL_switcher_halve_cpus() we already have a runtime validation check
to make sure we're dealing with only two clusters, so booting on a quad
cluster system will be caught and switcher activation aborted.
However, the b.L switcher must ensure the MCPM layer is initialized on
the booted hardware before doing anything. The mcpm_is_available()
function is added to that effect.

fixup_user_fault() is used by the futex code when the direct user access
fails, and the futex code wants it to either map in the page in a usable
form or return an error. It relied on handle_mm_fault() to map the
page, and correctly checked the error return from that, but while that
does map the page, it doesn't actually guarantee that the page will be
mapped with sufficient permissions to be then accessed.
So do the appropriate tests of the vma access rights by hand.
[ Side note: arguably handle_mm_fault() could just do that itself, but
we have traditionally done it in the caller, because some callers -
notably get_user_pages() - have been able to access pages even when
they are mapped with PROT_NONE. Maybe we should re-visit that design
decision, but in the meantime this is the minimal patch. ]

devpriv->iobase is currently being used to hold the iobase address used to
read/write the board's registers. The same address is stored in the
comedi_device dev->iobase. We use that instead. The eventual goal is to
decrease the driver's use of the struct addi_private, so that it may
eventually use a much slimmer specialized private struct instead, as the
other addi_apci_* drivers do.
