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

drivers: macintosh: rack-meter: limit idle ticks to total ticks

2016-04-12T11:05:20Z

Limit idle ticks to total ticks. This prevents the annoying rackmeter leds fully ON / OFF blinking state that happens on fully idling G5 Xserve systems. Signed-off-by: Aaro Koskinen Signed-off-by: Michael Ellerman

powerpc/rackmeter: Fix module autoload for OF platform driver

2015-11-26T11:11:18Z

This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Luis de Bethencourt Signed-off-by: Michael Ellerman

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.

drivers: clean-up prom.h implicit includes

Powerpc is a mess of implicit includes by prom.h. Add the necessary explicit includes to drivers in preparation of prom.h cleanup. Signed-off-by: Rob Herring Acked-by: Grant Likely

Drivers: macintosh: remove __dev* attributes.

2013-01-03T23:57:14Z

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, __devinitconst, 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.

[S390] cputime: add sparse checking and cleanup

2011-12-15T13:56:19Z

Make cputime_t and cputime64_t nocast to enable sparse checking to detect incorrect use of cputime. Drop the cputime macros for simple scalar operations. The conversion macros are still needed. Signed-off-by: Martin Schwidefsky

sched/accounting: Change cpustat fields to an array

This patch changes fields in cpustat from a structure, to an u64 array. Math gets easier, and the code is more flexible.
