macintosh: Convert to using %pOF instead of full_name

2017-09-01T06:42:52Z

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by: Rob Herring [mpe: Also convert the two cases inside #if 0] Signed-off-by: Michael Ellerman

macintosh/rack-meter: Make of_device_ids const

2017-08-21T07:21:34Z

of_device_ids are not supposed to change at runtime. All functions working with of_device_ids provided by work with const of_device_ids. So mark the non-const structs as const.

macintosh/rack-meter: Convert cputime64_t use to u64

2017-02-01T08:13:47Z

cputime_t is going to be removed and replaced by nsecs units, so convert the drivers/macintosh/rack-meter.c use to u64..

sched/cputime: Convert kcpustat to nsecs

2017-02-01T08:13:47Z

Kernel CPU stats are stored in cputime_t which is an architecture defined type, and hence a bit opaque and requiring accessors and mutators for any operation. Converting them to nsecs simplifies the code and is one step toward the removal of cputime_t in the core code.

powerpc: Remove all usages of NO_IRQ

2016-09-20T10:57:12Z

NO_IRQ has been == 0 on powerpc for just over ten years (since commit 0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change platforms to use it")). It's also 0 on most other arches. Although it's fairly harmless, every now and then it causes confusion when a driver is built on powerpc and another arch which doesn't define NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least some of which are to work around that problem. So we'd like to remove it. This is fairly trivial in the arch code, we just convert: if (irq == NO_IRQ) to if (!irq) if (irq != NO_IRQ) to if (irq) irq = NO_IRQ; to irq = 0; return NO_IRQ; to return 0; And a few other odd cases as well. At least for now we keep the #define NO_IRQ, because there is driver code that uses NO_IRQ and the fixes to remove those will go via other trees. Note we also change some occurrences in PPC sound drivers, drivers/ps3, and drivers/macintosh. Signed-off-by: Michael Ellerman

powerpc/rackmeter: Fix module autoload for OF platform driver

powerpc: Move Power Macintosh drivers to generic byteswappers

2015-03-23T03:29:40Z

ppc has special instruction forms to efficiently load and store values in non-native endianness. These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.
