Add SPDX license identifiers to all files which:

 - Have no license information of any form

 - Have EXPORT_.*_SYMBOL_GPL inside which was used in the
   initial scan/conversion to ignore the file

m68k: Drop ARCH_USES_GETTIMEOFFSET

2019-03-25T09:22:24+00:00

m68k: mac: Fix VIA timer counter accesses

2019-03-25T09:22:24+00:00

This resolves some bugs that affect VIA timer counter accesses.
Avoid lost interrupts caused by reading the counter low byte register.
Make allowance for the fact that the counter will be decremented to
0xFFFF before being reloaded.

m68k: Call timer_interrupt() with interrupts disabled

2019-03-25T09:22:24+00:00

Some platforms execute their timer handler with the interrupt priority
level set below 6. That means the handler could be interrupted by another
driver and this could lead to re-entry of the timer core.

Avoid this by use of local_irq_save/restore for timer interrupt dispatch.
This provides mutual exclusion around the timer interrupt flag access
which is needed later in this series for the clocksource conversion.

Merge tag 'char-misc-5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2019-03-06T22:18:59+00:00

Pull char/misc driver updates from Greg KH:
 "Here is the big char/misc driver patch pull request for 5.1-rc1.

  The largest thing by far is the new habanalabs driver for their AI
  accelerator chip. For now it is in the drivers/misc directory but will
  probably move to a new directory soon along with other drivers of this
  type.

  Other than that, just the usual set of individual driver updates and
  fixes. There's an "odd" merge in here from the DRM tree that they
  asked me to do as the MEI driver is starting to interact with the i915
  driver, and it needed some coordination. All of those patches have
  been properly acked by the relevant subsystem maintainers.

  All of these have been in linux-next with no reported issues, most for
  quite some time"

m68k: Dispatch nvram_ops calls to Atari or Mac functions

2019-01-22T09:21:45+00:00

A multi-platform kernel binary has to decide at run-time how to dispatch
the arch_nvram_ops calls. Add a platform-independent arch_nvram_ops
struct for this, to replace the atari-specific one.

Enable CONFIG_HAVE_ARCH_NVRAM_OPS for Macs.

PMU commands. Also implement the missing XPRAM accessors for VIA-based
Macs.
