2010-10-27MN10300: Reorder asm/cacheflush.h to put primitives firstDavid Howells
Reorder asm/cacheflush.h to put arch primitives first, before the main functions so that the main functions can be inline asm rather than #defines when non-trivial. Signed-off-by: David Howells <dhowells@redhat.com>
2010-10-27MN10300: Provide a MN10300_CACHE_ENABLED config optionDavid Howells
Provide a MN10300_CACHE_ENABLED config option as inverted logic of MN10300_CACHE_DISABLED to make things simpler. Signed-off-by: David Howells <dhowells@redhat.com>
2010-10-27MN10300: Cache: Split cache bits out of arch KconfigDavid Howells
Split the cache bits out of arch/mn10300/Kconfig as they're quite complex. Signed-off-by: David Howells <dhowells@redhat.com>

2010-10-27MN10300: Move DMA engine control reg defs to MN103E010 processor directoryAkira Takeuchi
Move the DMA engine control register definitions to the MN103E010 processor directory so that the MN2WS0050 processor can have its own.

2010-10-27MN10300: Differentiate AM33_2 and AM33_3 in configAkira Takeuchi
Differentiate AM33_2 and AM33_3 CPU cores in configuration. The MN103E010 processor contains an AM33_2 core. Whilst we're at it, prepare for AM34-based stuff by declaring AM34_2 too.

2010-10-27MN10300: Provide the functions to fully disable maskable interruptsAkira Takeuchi
The local_irq_disable() function and co. merely raise the interrupt mask on the MN10300 arch to exclude normal interrupts. This still lets other, higher priority maskable interrupts through, such as are used to service gdbstub's serial port and the MN10300 on-chip serial port virtual FIFOs. Provide functions to allow the maskable interrupts to be fully disabled, which will exclude those interrupts.

2010-10-27MN10300: Don't cast away the volatile in test_bit()Akira Takeuchi
Don't cast away the volatile in test_bit()'s parameter when we change its type from const volatile void * so that we can dereference it.

2010-10-27Typedef SMP call function pointerDavid Howells
Typedef the pointer to the function to be called by smp_call_function() and friends: typedef void (*smp_call_func_t)(void *info); as it is used in a fair number of places. Signed-off-by: David Howells <dhowells@redhat.com> cc: linux-arch@vger.kernel.org
2010-10-27MN10300: Prevent cnt32_to_63() from being preempted in sched_clock()David Howells
Prevent cnt32_to_63() from being preempted in sched_clock() because it may read its internal counter, get preempted, get delayed for more than the half period of the 'TSC' and then write the internal counter, thus corrupting it. Whilst some callers of sched_clock() have interrupts disabled or hold spinlocks, not all do, and so preemption must be held here. Note that sched_clock() is called from lockdep, but that shouldn't be a problem because although preempt_disable() calls into lockdep, lockdep has a recursion counter to deal with this.

2010-10-27x86: Add platform directoryThomas Gleixner
x86 has finally arrived in the embedded nightmare and will rapidly grow SoC platform support in various flavours. So we need a place for the platform support files.

2010-10-27sh64: oprofile: Fix up kernel stack pointer size mismatch.Paul Mundt
For the backtrace code its assumed that the stack pointer is 32-bits, which is not the case with the sh64 registers. Use the shared kernel_stack_pointer() helper to get at the actual register, which already takes care of the necessary typecasting. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-27sh: oprofile: Fix up and extend op_name_from_perf_id().Paul Mundt
op_name_from_perf_id() currently returns a local variable, which isn't terribly productive. As we only handle a single PMU case for now, simply allocate and free the string from the arch init/exit context and have op_name_from_perf_id() hand back the cached string. This also takes UTS_MACHINE in to account, given that we build for multiple architectures. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-10-27ALSA: usb-audio: automatically detect feedback formatClemens Ladisch
There are two USB Audio Class specifications (v1 and v2), but neither of them clearly defines the feedback format for high-speed UAC v1 devices. Add to this whatever the Creative and M-Audio firmware writers have been smoking, and it becomes impossible to predict the exact feedback format used by a particular device. Therefore, automatically detect the feedback format by looking at the magnitude of the first received feedback value. Also, this allows us to get rid of some special cases for E-Mu devices.
