Greg Kroah-Hartman 7c9503b838 SPARC: drivers: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Paul Gortmaker 066bcaca51 sparc: move symbol exporters to use export.h not module.h
Many of the core sparc kernel files are not modules, but just
including module.h for exporting symbols.  Now these files can
use the lighter footprint export.h for this role.

David S. Miller 3628aa0657 sparc64: Fix section mis-match errors.
Fix all of the problems spotted by CONFIG_DEBUG_SECTION_MISMATCH under
arch/sparc during a 64-bit defconfig build.

They fall into two categorites:

1) of_device_id is marked as __initdata, and we can never do this
   since these objects sit in the device core data structures way
   past boot.  So even if a driver will never be reloaded, we have
   to keep the device ID table around.

   Mark such cases const instead.

2) The bootmem alloc/free handling code in mdesc.c was not fully
   marked __init as it should be, thus generating a reference
   to free_bootmem_late() (which is __init) from non-__init code.

Grant Likely 1ab1d63a85 of/platform: remove all of_bus_type and of_platform_bus_type references
Both of_bus_type and of_platform_bus_type are just #define aliases
for the platform bus.  This patch removes all references to them and
switches to the of_register_platform_driver()/of_unregister_platform_driver()
API for registering.

Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim.  At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.

Grant Likely 4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated.  This patch
makes all readers of these elements use device.of_node instead.

David S. Miller 7466bd3caa sparc64: Fix clock event multiplier printf format.
The type got changed to u32, so %lx generated warnings
(and thus build failure on sparc64)

Stephen Rothwell fixed it like so:

-	printk("clockevent: mult[%lx] shift[%d]\n",
+	printk("clockevent: mult[%ux] shift[%d]\n",

But that's not a valid transformation, we now get:

clockevent: mult[51539607x] shift[32]

in the logs.

Fix it to use the correct plain "%x" instead.

Alexey Dobriyan 405f55712d headers: smp_lock.h redux
* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Mike Travis d2287f5ebe irq: update all arches for new irq_desc, fix
Impact: fix build errors

Since the SPARSE IRQS changes redefined how the kstat irqs are
organized, arch's must use the new accessor function:

	kstat_incr_irqs_this_cpu(irq, DESC);

If CONFIG_SPARSE_IRQS is set, then DESC is a pointer to the
irq_desc which has a pointer to the kstat_irqs.  If not, then
the .irqs field of struct kernel_stat is used instead.

Sam Ravnborg 9018113649 sparc64: Use unsigned long long for u64.
Andrew Morton wrote:

    People keep on doing

            printk("%llu", some_u64);

    testing it only on x86_64 and this generates a warning storm on
    powerpc, sparc64, etc.  Because they use `long', not `long long'.

    Quite a few 64-bit architectures are using `long' for their
    s64/u64 types.  We should convert them all to `long long'.

Update types.h so we use unsigned long long for u64 and
fix all warnings in sparc64 code.
Tested with an allnoconfig, defconfig and allmodconfig builds.

This patch introduces additional warnings in several drivers.
These will be dealt with in separate patches.
