Merge branch 'for-armsoc' of git://git.linaro.org/people/rmk/linux-arm
Pull #1 ARM updates from Russell King: "This one covers stuff which Arnd is waiting for me to push, as this is shared between both our trees and probably other trees elsewhere. Essentially, this contains: - AMBA primecell device initializer updates - mostly shrinking the size of the device declarations in platform code to something more reasonable. - Getting rid of the NO_IRQ crap from AMBA primecell stuff. - Nicolas' idle cleanups. This in combination with the restart cleanups from the last merge window results in a great many mach/system.h files being deleted." Yay: ~80 files, ~2000 lines deleted. * 'for-armsoc' of git://git.linaro.org/people/rmk/linux-arm: (60 commits) ARM: remove disable_fiq and arch_ret_to_user macros ARM: make entry-macro.S depend on !MULTI_IRQ_HANDLER ARM: rpc: make default fiq handler run-time installed ARM: make arch_ret_to_user macro optional ARM: amba: samsung: use common amba device initializers ARM: amba: spear: use common amba device initializers ARM: amba: nomadik: use common amba device initializers ARM: amba: u300: use common amba device initializers ARM: amba: lpc32xx: use common amba device initializers ARM: amba: netx: use common amba device initializers ARM: amba: bcmring: use common amba device initializers ARM: amba: ep93xx: use common amba device initializers ARM: amba: omap2: use common amba device initializers ARM: amba: integrator: use common amba device initializers ARM: amba: realview: get rid of private platform amba_device initializer ARM: amba: versatile: get rid of private platform amba_device initializer ARM: amba: vexpress: get rid of private platform amba_device initializer ARM: amba: provide common initializers for static amba devices ARM: amba: make use of -1 IRQs warn ARM: amba: u300: get rid of NO_IRQ initializers ...
