2009-08-13netx: Use get_irqnr_preamble to initialize base registerUwe Kleine-König
This patch optimizes the irq handling a bit. Now the base register is only computed once per irq exception instead of at least twice. Moreover the mov+add sequence is simplified to an ldr (which might save some cycles depending on memory timing). Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
2009-05-07[ARM] VIC: Add power management deviceBen Dooks
Add power management support to the VIC by registering each VIC as a system device to get suspend/resume events going. Since the VIC registeration is done early, we need to record the VICs in a static array which is used to add the system devices later once the initcalls are run. This means there is now a configuration value for the number of VICs in the system. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-03-19[ARM] pass reboot command line to arch_reset()Russell King
OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

2008-11-30[ARM] Add a common typesafe __io implementationRussell King

2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

2008-11-29[ARM] move MAX_DMA_ADDRESS to mach/memory.hRussell King
Move the definition of MAX_DMA_ADDRESS from mach/dma.h to mach/memory.h, thereby placing it along side its relative, ISA_DMA_THRESHOLD. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre
Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

Move the xtime write mode seqlock into timer_tick(), so it only surrounds the call to do_timer(). This avoids a deadlock in update_process_times() ... hrtimer_get_softirq_time() which tries to get a read mode seqlock on xtime, thereby preventing booting.
