powerpc: Move Power Macintosh drivers to generic byteswappers

2015-03-23T03:29:40+00:00

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

2013-10-10T01:04:04+00:00

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.

2013-01-03T23:57:14+00:00

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

2011-12-15T13:56:19+00:00

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

2011-12-06T08:06:38+00:00

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

powerpc/macintosh: Fix __devexit annotation in rack-meter.c

2011-03-02T05:50:25+00:00

The following warning was seen building rack-meter.c WARNING: drivers/built-in.o(.text+0xac784): Section mismatch in reference from the function rackmeter_shutdown() to the function .devexit.text:rackmeter_stop_cpu_sniffer() The function rackmeter_shutdown() references a function in an exit section. Often the function rackmeter_stop_cpu_sniffer() has valid usage outside the exit section and the fix is to remove the __devexit annotation of rackmeter_stop_cpu_sniffer. This patch resolves the warning by removing the __devexit annotation from rackmeter_stop_cpu_sniffer().

workqueue: convert cancel_rearming_delayed_work[queue]() users to cancel_delayed_work_sync()

2010-12-15T09:56:11+00:00

cancel_rearming_delayed_work[queue]() has been superceded by cancel_delayed_work_sync() quite some time ago. Convert all the in-kernel users. The conversions are completely equivalent and trivial.

powerpc/macio: Fix probing of macio devices by using the right of match table

2010-06-02T07:50:38+00:00

Grant patches added an of mach table to struct device_driver. However, while he changed the macio device code to use that, he left the match table pointer in struct macio_driver and didn't update drivers to use the "new" one, thus breaking the probing. This completes the change by moving all drivers to setup the "new" one, removing all traces of the old one, and while at it (since it changes the exact same locations), I also remove two other duplicates from struct driver which are the name and owner fields.

of: Always use 'struct device.of_node' to get device node pointer.

2010-05-18T22:10:44+00:00

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. (struct of_device *)->node (struct dev_archdata *)->prom_node (sparc) (struct dev_archdata *)->of_node (powerpc & microblaze) Signed-off-by: Grant Likely
