2010-04-21sh: Tidy CPU probing and fixup section annotations.Paul Mundt6-18/+7
This does a detect_cpu_and_cache_system() -> cpu_probe() rename, tidies up the unused return value, and stuffs it under __cpuinit in preparation for CPU hotplug. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-21sh: hw-breakpoints: Kill off stub unthrottle callback.Paul Mundt1-5/+0
This follows the x86 change and kills off the unthrottle stub. As the x86 change killed off the generic callback it isn't used anymore anyways. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-04-15sh: intc: IRQ auto-distribution support.Paul Mundt2-26/+59
This implements support for hardware-managed IRQ balancing as implemented by SH-X3 cores (presently only hooked up for SH7786, but can probably be carried over to other SH-X3 cores, too). CPUs need to specify their distribution register along with the mask definitions, as these follow the same format. Peripheral IRQs that don't opt out of balancing will be automatically distributed at the whim of the hardware block, while each CPU needs to verify whether it is handling the IRQ or not, especially before clearing the mask.

2010-04-15sh: Disable IRQ balancing for timer and IPI IRQs.Paul Mundt1-2/+2
Make sure that the timer IRQs and IPIs aren't enabled for IRQ balancing. IPIs are disabled as a result of being percpu while the timers simply disable balancing outright. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-13sh: intc: userimask support.Paul Mundt1-0/+3
This adds support for hardware-assisted userspace irq masking for special priority levels. Due to the SR.IMASK interactivity, only some platforms implement this in hardware (including but not limited to SH-4A interrupt controllers, and ARM-based SH-Mobile CPUs). Each CPU needs to wire this up on its own, for now only SH7786 is wired up as an example. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-03-29sh: Enable the mmu in start_secondary()Matt Fleming1-0/+1
For the boot, enable_mmu() is called from setup_arch() but we don't call setup_arch() for any of the other cpus. So turn on the non-boot cpu's mmu inside of start_secondary(). I noticed this bug on an SMP board when trying to map I/O memory (smsc911x registers) into the kernel address space. Since the Address Translation bit in MMUCR wasn't set, accessing the virtual address where the smsc911x registers were supposedly mapped actually performed a physical address access.

Add generic implementations of the old and really old uname system calls.

2010-03-12Add generic sys_ipc wrapperChristoph Hellwig1-104/+0
Add a generic implementation of the ipc demultiplexer syscall. Except for s390 and sparc64 all implementations of the sys_ipc are nearly identical. There are slight differences in the types of the parameters, where mips and powerpc as the only 64-bit architectures with sys_ipc use unsigned long for the "third" argument as it gets casted to a pointer later, while it traditionally is an "int" like most other paramters. frv goes even further and uses unsigned long for all parameters execept for "ptr" which is a pointer type everywhere. The change from int to unsigned long for "third" and back to "int" for the others on frv should be fine due to the in-register calling conventions for syscalls (we already had a similar issue with the generic sys_ptrace), but I'd prefer to have the arch maintainers looks over this in details. Except for that h8300, m68k and m68knommu lack an impplementation of the semtimedop sub call which this patch adds, and various architectures have gets used - at least on i386 it seems superflous as the compat code on x86-64 and ia64 doesn't even bother to implement it.

2010-03-10serial: sh-sci: clkdev updates for MSTP gating.Paul Mundt13-60/+34
This fixes up some of the I/D/F clock ambiguity in the sh-sci driver. The interface clock in most cases just wraps back to the peripheral clock, while the function clock wraps in to the MSTP bits. As the logic was somewhat inverted, this cleans that up, and also enables all CPUs with SCI MSTP bits to match function clocks through clkdev lookup. As a result, this gets rid of the clk string abuse on the sh side, and the clock string will be killed off once the ARM code has had a chance to sync up. This also enables MSTP gating on CPUs like 7786 which had never wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785, and SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Acked-by: David Teigland <teigland@redhat.com> Acked-by: Matt Domsch <Matt_Domsch@dell.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Acked-by: Hans J.
