* [ARM] 3537/1: Rework DMA-bounce locking for finer granularityKevin Hilman2006-06-22
| | | | | | | | | | | | | | | Patch from Kevin Hilman This time with IRQ versions of locks. Rework also enables compatability with realtime-preemption patch. With the current locking via interrupt disabling, under RT, potentially sleeping functions can be called with interrupts disabled.

| | | | | | | | | | | | Patch from Pavel Pisa There has been bug, that dma_err_handler() touches even channels not signaling error condition. Problem noticed by Andrea Paterniani. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 3597/1: ixp4xx/nslu2: Board support for new LED subsystemRod Whitby2006-06-22
| | | | | | | | | | | | | | | | Patch from Rod Whitby This patch implements NEW_LEDS support for the Linksys NSLU2. The NSLU2 has four LED indicators, which are the only form of output for an unmodified device - there is no keyboard or display on an NSLU2. For an NSLU2 which has been modified to bring out the serial port console, it is important to register that device first separately, to enable debugging of other device support.

* [ARM] 3626/1: ARM EABI: fix syscall restartingNicolas Pitre2006-06-22
| | | | | | | | | | | | | | | | | | | Patch from Nicolas Pitre The RESTARTBLOCK case currently store some code on the stack to invoke sys_restart_syscall. However this is ABI dependent and there is a mismatch with the way __NR_restart_syscall gets defined when the kernel is compiled for EABI. There is also a long standing bug in the thumb case since with OABI the __NR_restart_syscall value includes __NR_SYSCALL_BASE which should not be the case for Thumb syscalls.

| | | | | | | | | | | | | | Patch from Ben Dooks Add a get_rate call to allow an given clock to over-ride the clk_get_rate() call. This provides support for clocks which rely on division of their parent to correctly report their frequency when the parent can also change.

| | | | | | | | | | | | | | | Patch from Ben Dooks Split the s3c2410 specific clocks from the core clock code, as part of the work to support more of the Samsung line of SoCs. The patch does not use the sysdev mechanism as the clocks are needed for the timer init, which is very early in the kernel init sequence.

* [ARM] Enable VFP to be built when non-VFP capable CPUs are selectedRussell King2006-06-22
| | | | | | | | | | | | | | | | Since we pass flags to the compiler to control code generation based on the least capable selected CPU, if we want to include VFP support, we must tweak the assembler flags to allow the VFP instructions. Moreover, we must not use the mrrc/mcrr versions since these will not be recognised by the assembler. We do not convert all instructions to the VFP-equivalent (yet) since binutils appears to barf on "fmrx rn, fpinst" and doesn't provide any other way (other than using the mrc equivalent) to encode this instruction - which is rather a problem when you have a VFP implementation which requires these instructions.

* [ARM] Add thread_notify infrastructureRussell King2006-06-22
| | | | | | | | | | | | | Some machine classes need to allow VFP support to be built into the kernel, but still allow the kernel to run even though VFP isn't present. Unfortunately, the kernel hard-codes VFP instructions into the thread switch, which prevents this being run-time selectable. Solve this by introducing a notifier which things such as VFP can hook into to be informed of events which affect the VFP subsystem (eg, creation and destruction of threads, switches between threads.)
