2013-01-03MIPS: drivers: remove __dev* attributes.Greg Kroah-Hartman1-1/+1
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.

2012-12-13MIPS: Kconfig: Rename several firmware related config symbols.Ralf Baechle1-4/+4
With the upcoming merge of the ARC architecture there is a small likelyhood of conflicting use for the CONFIG_ARC config symbol. Rename it to CONFIG_FW_ARC. Also rename CONFIG_ARC32 to CONFIG_FW_ARC32, CONFIG_ARC64 to CONFIG_FW_ARC64. For consistence also rename CONFIG_SNIPROM to CONFIG_FW_SNIPROM and CONFIG_CFE to CONFIG_FW_CFE.

2012-05-29Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linusLinus Torvalds1-0/+1
Pull MIPS updates from Ralf Baechle: "The whole series has been sitting in -next for quite a while with no complaints. The last change to the series was before the weekend the removal of an SPI patch which Grant - even though previously acked by himself - appeared to raise objections. So I removed it until the situation is clarified. Other than that all the patches have the acks from their respective maintainers, all MIPS and x86 defconfigs are building fine and I'm not aware of any problems introduced by this series. Among the key features for this patch series is a sizable patchset for Lantiq which among other things introduces support for Lantiq's flagship product, the FALCON SOC. It also means that the opensource developers behind this patchset have overtaken Lantiq's competing inhouse development team that was working behind closed doors. Less noteworthy the ath79 patchset which adds support for a few more chip variants, cleanups and fixes. Finally the usual dose of tweaking of generic code." Fix up trivial conflicts in arch/mips/lantiq/xway/gpio_{ebu,stp}.c where printk spelling fixes clashed with file move and eventual removal of the printk. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (81 commits) MIPS: lantiq: remove orphaned code MIPS: Remove all -Wall and almost all -Werror usage from arch/mips.

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]).
