Pull libnvdimm updates from Dan Williams:
 "The bulk of this update was stabilized before the merge window and
  appeared in -next.  The "device dax" implementation was revised this
  week in response to review feedback, and to address failures detected
  by the recently expanded ndctl unit test suite.

  Not included in this pull request are two dax topic branches (dax
  error handling, and dax radix-tree locking).  These topics were
  deferred to get a few more days of -next integration testing, and to
  coordinate a branch baseline with Ted and the ext4 tree.  Vishal and
  Ross will send the error handling and locking topics respectively in
  the next few days.

  This branch has received a positive build result from the kbuild robot
  across 226 configs.

  Summary:

   - Device DAX for persistent memory: Device DAX is the device-centric
     analogue of Filesystem DAX (CONFIG_FS_DAX).  It allows memory
     ranges to be allocated and mapped without need of an intervening
     file system.  Device DAX is strict, precise and predictable.
     Specifically this interface:

      a) Guarantees fault granularity with respect to a given page size
         (pte, pmd, or pud) set at configuration time.

      b) Enforces deterministic behavior by being strict about what
         fault scenarios are supported.

     Persistent memory is the first target, but the mechanism is also
     targeted for exclusive allocations of performance/feature
     differentiated memory ranges.

   - Support for the HPE DSM (device specific method) command formats.
     This enables management of these first generation devices until a
     unified DSM specification materializes.

   - Further ACPI 6.1 compliance with support for the common dimm
     identifier format.

   - Various fixes and cleanups across the subsystem"

   - Soumya PN sent me a clean up patch to not disable interrupts when
     taking the tasklist_lock for read, as it's unnecessary because that
     lock is never taken for write in irq context.

   - Newer gcc's can cause the jump in the function_graph code to the
     global ftrace_stub label to be a short jump instead of a long one.
     As that jump is dynamically converted to jump to the trace code to
     do function graph tracing, and that conversion expects a long jump
     it can corrupt the ftrace_stub itself (it's directly after that
     call).  One way to prevent gcc from using a short jump is to
     declare the ftrace_stub as a weak function, which we do here to
     keep gcc from optimizing too much"

I'm looking at trying to possibly merge the 32-bit and 64-bit versions
of the x86 uaccess.h implementation, but first this needs to be cleaned
up.

For example, the 32-bit version of "__copy_from_user_inatomic()" is
mostly the special cases for the constant size, and it's actually almost
never relevant.  Most users aren't actually using a constant size
anyway, and the few cases that do small constant copies are better off
just using __get_user() instead.

So get rid of the unnecessary complexity.

Testing the dax-device autodetect support revealed a probe failure with
the following result:

    dax0.1: bad offset: 0x8200000 dax disabled

The original pfn-device implementation inferred the alignment from
ilog2(offset), now that the alignment is explicit the is_power_of_2()
needs replacing with a real sanity check against the recorded alignment.
Otherwise the alignment check is useless in the implicit case and only
the minimum size of the offset matters.

This self-consistency check is further validated by the probe path that
will re-check that the offset is large enough to contain all the
metadata required to enable the device.

Commit b3c1be1b ("base: isa: Remove X86_32 dependency") made ISA
support available on x86-64 too.  That's not right - while there are
some LPC-style devices that might be useful still and be based on
ISA-like IP blocks, that is *not* an excuse to try to enable any random
legacy drivers.

Such drivers should be individually enabled and made to perhaps depend
on ISA_DMA_API instead (which we have continued to support on x86-64).
Or we could add another "ISA_XYZ_API" that we support that doesn't
enable random old drivers that aren't even 64-bit clean nor do we have
any test coverage for.

Turning off ISA will now also turn off some drivers that have been
marked as depending on it as part of this series, and that used to work
on modern platforms.

See for example commits ad7afc38..cc736607, which may also need
to be reverted.

This commit means that the warnings that came in due to enabling ISA
widely are now gone again.

This moves the table inside of the #ifdef section that has the
only user, to avoid the harmless warning.

The R2025SD chip, according to its data sheet, sets the /XST
bit to zero if the oscillator stops. Hence the check for this
condition was wrong.

The bin2bcd function in set_time is uncorrect on weekdays as the
bit mask should be done at the end of arithmetic operations.

The RTC RV3029 handles different types of alarms : seconds, minutes, ...
These alarms can be enabled or disabled individually using an AE_x bit
which is the last bit (BIT(7)) on each alarm registers.

To prepare the alarm IRQ support, the current code enables all the alarm
types by setting each AE_x to 1.
It also fixes others alarms issues :
   - month and weekday errors : it was performing -1 instead of +1.
   - wrong use of bit mask with bin2bcd

Remove some checks from checkpatch such as spaces around arithmetic

To prepare the use of regmap to add the support of RV-3049, all the
'i2c' in functions's names are removed.
