2010-11-07ARM: 6470/1: atomic64: use generic implementation for OABI configurationsWill Deacon1-1/+1
The old apcs-gnu ABI doesn't guarantee that double words are allocated to registers with even alignment, causing the 64-bit exclusive memory operations to be rejected by the assembler. This patch requires that CONFIG_AEABI is set in order to use the native atomic operations and falls back to the generic (spinlock) code otherwise.

2010-10-18irq_work: Add generic hardirq context callbacksPeter Zijlstra1-0/+1
Provide a mechanism that allows running code in IRQ context. It is most useful for NMI code that needs to interact with the rest of the system -- like wakeup a task to drain buffers. Perf currently has such a mechanism, so extract that and provide it as a generic feature, independent of perf so that others may also benefit. The IRQ context callback is generated through self-IPIs where possible, or on architectures like powerpc the decrementer (the built-in timer facility) is set to generate an interrupt immediately. Architectures that don't have anything like this get to do with a callback from the timer tick. These architectures can call irq_work_run() at the tail of any IRQ handlers that might enqueue such work (like the perf IRQ handler) to avoid undue latencies in processing the work.

2010-10-04ARM: Allow SMP kernels to boot on UP systemsRussell King1-0/+13
UP systems do not implement all the instructions that SMP systems have, so in order to boot a SMP kernel on a UP system, we need to rewrite parts of the kernel. Do this using an 'alternatives' scheme, where the kernel code and data is modified prior to initialization to replace the SMP instructions, thereby rendering the problematical code ineffectual. We use the linker to generate a list of 32-bit word locations and their replacement values, and run through these replacements when we detect a UP system.

2010-10-04ARM: Simplify SMP/SCU/TWD dependenciesRussell King1-10/+7

On the r2p0, r2p1 and r2p2 versions of the Cortex-A9, data corruption can occur if a shared cache line is replaced on one CPU as another CPU is accessing it. This workaround sets two bits in the diagnostic register of the Cortex-A9, reducing the linefill issuing capabilities of the processor and avoiding the erroneous behaviour.

On versions of the Cortex-A9 up to and including r2p2, under rare circumstances, a DMB instruction between 2 write operations may not ensure the correct visibility ordering of the 2 writes. This workaround sets a bit in the diagnostic register of the Cortex-A9, causing the DMB instruction to behave like a DSB, which functions correctly on the affected cores.
