Finn Thain 558d5ad276 m68k/mac: Avoid soft-lockup warning after mach_power_off
Disable interrupts for power-off, like other platforms do. This prevents
meaningless warnings from the soft-lockup detector on models with a power
supply unit not under software control.

Testing shows that the CUDA_POWERDOWN command never completes (for a
Centris 660av or LC 475, at least). So, don't wait for command completion
on those Cuda-based models that do not support soft power. Just proceed to

Masahiro Yamada 5608e72dfd m68k: move generic-y of exported headers to uapi/asm/Kbuild
Since commit fcc8487d47 ("uapi: export all headers under uapi
directories"), all (and only) headers under uapi directories are
exported, but asm-generic wrappers are still exceptions.

To complete de-coupling the uapi from kernel headers, move generic-y
of exported headers to uapi/asm/Kbuild.

With this change, "make headers_install" will just need to parse
uapi/asm/Kbuild to build up exported headers.

For m68k, "generic-y += termios.h" is doubled in asm/Kbuild and
uapi/asm/Kbuild.  So, the one in the former can be simply removed.

Also, move "generic-y += kprobes.h" up in order to keep the entries
sorted.

In this new subsystem we'll try to properly maintain all the generic
 code related to dma-mapping, and will further consolidate arch code

 This pull request contains:
 
  - removal of the DMA_ERROR_CODE macro, replacing it with calls
    to ->mapping_error so that the dma_map_ops instances are
    more self contained and can be shared across architectures (me)
  - removal of the ->set_dma_mask method, which duplicates the
    ->dma_capable one in terms of functionality, but requires more
    duplicate code.
  - various updates for the coherent dma pool and related arm code
    (Vladimir)
  - various smaller cleanups (me)

Vladimir Murzin 07c75d7a6b drivers: dma-mapping: allow dma_common_mmap() for NOMMU
Currently, internals of dma_common_mmap() is compiled out if build is
done for either NOMMU or target which explicitly says it does not
have/want coherent DMA mmap. It turned out that dma_common_mmap() can
be handy in NOMMU setup (at least for ARM).

This patch converts exitent NOMMU targets to use ARCH_NO_COHERENT_DMA_MMAP,
thus when CONFIG_MMU is gone from dma_common_mmap() their behaviour stays
unchanged.

ARM is not converted to ARCH_NO_COHERENT_DMA_MMAP because it 1)
already has mmap callback which can handle (at some extent) NOMMU 2)
already defines dummy pgprot_noncached() for NOMMU build.

c6x and frv stay untouched since they already have ARCH_NO_COHERENT_DMA_MMAP.

Andreas Schwab 204a2be30a m68k: Remove ptrace_signal_deliver
This fixes debugger syscall restart interactions.  A debugger that
modifies the tracee's program counter is expected to set the orig_d0
pseudo register to -1, to disable a possible syscall restart.

This removes the last user of the ptrace_signal_deliver hook in the ptrace
signal handling, so remove that as well.

Nicolas Dichtel fcc8487d47 uapi: export all headers under uapi directories
Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h

exported directories (like .install or .install.cmd).

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:

Nicolai Stange 33ae7a9b6c m68k/coldfire/pit: Set ->min_delta_ticks and ->max_delta_ticks
In preparation for making the clockevents core NTP correction aware,
all clockevent device drivers must set ->min_delta_ticks and
->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a
clockevent device's rate is going to change dynamically and thus, the
ratio of ns to ticks ceases to stay invariant.

Make the m68k arch's coldfire clockevent driver initialize these fields
properly.

This patch alone doesn't introduce any change in functionality as the
clockevents core still looks exclusively at the (untouched) ->min_delta_ns
and ->max_delta_ns. As soon as this has changed, a followup patch will
purge the initialization of ->min_delta_ns and ->max_delta_ns from this
driver.
