Pull ARM SoC cleanups from Arnd Bergmann: "A large number of cleanups, all over the platforms. This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup. The overall reduction in total code lines is mostly the result of removing broken and obsolete code." * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (133 commits) ARM: mvebu: correct gated clock documentation ARM: kirkwood: add missing include for nsa310 ARM: exynos: move exynos4210-combiner to drivers/irqchip mfd: db8500-prcmu: update resource passing drivers/db8500-cpufreq: delete dangling include ARM: at91: remove NEOCORE 926 board sunxi: Cleanup the reset code and add meaningful registers defines ARM: S3C24XX: header mach/regs-mem.h local ARM: S3C24XX: header mach/regs-power.h local ARM: S3C24XX: header mach/regs-s3c2412-mem.h local ARM: S3C24XX: Remove plat-s3c24xx directory in arch/arm/ ARM: S3C24XX: transform s3c2443 subirqs into new structure ARM: S3C24XX: modify s3c2443 irq init to initialize all irqs ARM: S3C24XX: move s3c2443 irq code to irq.c ARM: S3C24XX: transform s3c2416 irqs into new structure ARM: S3C24XX: modify s3c2416 irq init to initialize all irqs ARM: S3C24XX: move s3c2416 irq init to common irq code ARM: S3C24XX: Modify s3c_irq_wake to use the hwirq property ARM: S3C24XX: Move irq syscore-ops to irq-pm clocksource: always define CLOCKSOURCE_OF_DECLARE ...

2013-01-03ARCH: drivers remove __dev* attributes.Greg Kroah-Hartman1-2/+2
This fixes up all of the smaller arches that had __dev* markings for their platform-specific drivers. 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, __devinitconst, and __devexit from these drivers.

2012-12-24time: convert arch_gettimeoffset to a pointerStephen Warren1-6/+10
Currently, whenever CONFIG_ARCH_USES_GETTIMEOFFSET is enabled, each arch core provides a single implementation of arch_gettimeoffset(). In many cases, different sub-architectures, different machines, or different timer providers exist, and so the arch ends up implementing arch_gettimeoffset() as a call-through-pointer anyway. Examples are ARM, Cris, M68K, and it's arguable that the remaining architectures, M32R and Blackfin, should be doing this anyway. Modify arch_gettimeoffset so that it itself is a function pointer, which the arch initializes. This will allow later changes to move the initialization of this function into individual machine support or timer drivers. This is particularly useful for code in drivers/clocksource which should rely on an arch-independant mechanism to register their implementation of arch_gettimeoffset(). This patch also converts the Cris architecture to set arch_gettimeoffset directly to the final implementation in time_init(), because Cris already had separate time_init() functions per sub-architecture. M68K and ARM are converted to set arch_gettimeoffset to the final implementation in later patches, because they already have function pointers in place for this purpose.

2012-10-01m68k: switch to generic sys_execve()/kernel_execve()Al Viro3-37/+5
The tricky part here is that task_pt_regs() on m68k works *only* for process inside do_signal(). However, we need something much simpler - pt_regs of a process inside do_signal() may be at different offsets from the stack bottom, depending on the way we'd entered the kernel, but for a task inside sys_execve() it *is* at constant offset. Moreover, for a kernel thread about to become a userland process the same location is also fine - setting sp to that will leave the kernel stack pointer at the very bottom of the kernel stack when we finally switch to userland.

2012-09-23m68k: Add missing RCU idle APIs on idle loopFrederic Weisbecker1-0/+3
In the old times, the whole idle task was considered as an RCU quiescent state. But as RCU became more and more successful overtime, some RCU read side critical section have been added even in the code of some architectures idle tasks, for tracing for example. So nowadays, rcu_idle_enter() and rcu_idle_exit() must be called by the architecture to tell RCU about the part in the idle loop that doesn't make use of rcu read side critical sections, typically the part that puts the CPU in low power mode. This is necessary for RCU to find the quiescent states in idle in order to complete grace periods. Add this missing pair of calls in the m68k's idle loop. Reported-by: Paul E.

2012-07-17m68k: common PCI support definitions and codeGreg Ungerer2-0/+110
Basic set of definitions and support code required to turn on CONFIG_PCI for the m68k architecture. Nothing specific to any PCI implementation in any m68k class CPU hardware yet. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
2012-07-17m68k: add support for DMA_BIDIRECTIONAL in dma support functionsGreg Ungerer1-0/+1
The dma cache support functions do not currently support the direction flag DMA_BIDIRECTIONAL. If a driver passes this direction to dma_map_single or friends you will get console output like this: dma_sync_single_for_device: unsupported dir 0 For example when using the Intel e100 ethernet driver on a ColdFire platform with PCI bus. You will get a stream of these messages coming out. Modify the dma cache support code adding support for DMA_BIDIRECTIONAL. It is actioned by doing a cache push operation.

2012-07-16m68k: use simpler dma_alloc_coherent() for ColdFire CPUsGreg Ungerer1-2/+2
On all ColdFire platforms (whether MMU enabled or not) we want to use the simple page based dma_alloc_coherent. We don't want the virtual mapping version that is used on classic m68k setups. So modify the conditionals to use the existing simpler dma_alloc_coherent on all ColdFire and non-MMU builds. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2012-07-16m68k: merge the MMU and non-MMU versions of the entry.S codeGreg Ungerer3-552/+449
Some of the entry.S code is common to both MMU and non-MMU builds. So merge the entry_no.S and entry_mm.S files back into a single file. With a little code movement we only need a single #ifdef. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
2012-07-16m68k: use jbsr to call functions instead of bsrlGreg Ungerer1-2/+2
There is a few places that the m68k entry code uses the bsrl instruction to call other functions. That instruction is only supported on 68020 and higher CPU types. If we use jbsr instead the code will be clean for all 68k and ColdFire CPU types. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
2012-07-16m68k: use some direct calls to ret_from_exception in entry codeGreg Ungerer1-3/+3
The ret_from_excption code is referenced by its function name, or by a label set at the start of its code. The non-MMU code can share some of this code if we make direct calls to ret_from_exception instead of the associated label. The effected function paths are: buserr, trap and ret_from_fork. So change these to branch directly to ret_from_exception. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
2012-06-27m68k: Replace m68k-specific _[se]bss by generic __bss_{start,stop}Geert Uytterhoeven4-8/+2

2012-06-12m68k: make syscall_trace_enter/leave exist for non-MMU classic m68k typesGreg Ungerer1-1/+1
The assembler entry code calls directly to the syscall_trace_enter() and syscall_trace_leave() functions. But currently they are conditionaly compiled out for the non-MMU classic m68k CPU types (so 68328 for example), resulting in a link error: LD vmlinux arch/m68k/platform/68328/built-in.o: In function `do_trace': (.text+0x1c): undefined reference to `syscall_trace_enter' arch/m68k/platform/68328/built-in.o: In function `do_trace': (.text+0x4c): undefined reference to `syscall_trace_leave' Change the conditional check that includes these functions to be true for the !defined(CONFIG_MMU) case as well.

2012-06-12m68k: fix inclusion of arch_gettimeoffset for non-MMU 68k classic CPU typesGreg Ungerer1-2/+2
When building for non-MMU based classic 68k CPU types (like the 68328 for example) you get a compilation error: CC arch/m68k/kernel/time.o arch/m68k/kernel/time.c:91:5: error: redefinition of ‘arch_gettimeoffset’ include/linux/time.h:145:19: note: previous definition of ‘arch_gettimeoffset’ was here The arch_gettimeoffset() code is included when building for these CPU types, but it shouldn't be. Those machine types do not have CONFIG_ARCH_USES_GETTIMEOFFSET set. The fix is simply to conditionally include the arch_gettimeoffset() code on that same config setting that specifies its use or not.

2012-06-01new helper: signal_delivered()Al Viro1-1/+1
Does block_sigmask() + tracehook_signal_handler(); called when sigframe has been successfully built. All architectures converted to it; block_sigmask() itself is gone now (merged into this one). I'm still not too happy with the signature, but that's a separate story (IMO we need a structure that would contain signal number + siginfo + k_sigaction, so that get_signal_to_deliver() would fill one, signal_delivered(), handle_signal() and probably setup...frame() - take one).
