2008-12-14[ARM] eliminate NULL test and memset after alloc_bootmemJulia Lawall
As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b, alloc_bootmem and related functions never return NULL and always return a zeroed region of memory. Thus a NULL test or memset after calls to these functions is unnecessary. This was fixed using the following semantic patch.

2008-12-14[ARM] KS8695: Fixup the KS8695 GPIO to be GPIOLIBDaniel Silverstone
This patch is as small a change as possible to the KS8695 GPIO layer to use GPIOLIB to allow the generic GPIO expanders and the like to be compiled. As a side-effect, we also remove __init_or_module from several functions which could be called by drivers such as i2c-gpio which could plausibly be compiled into a non-modular kernel.

2008-12-14[ARM] KS8695: Fix up device registration.Daniel Silverstone
The KS8695 device.c provides registration functionality for the KS8695's various devices such as watchdog timers and ethernet devices. Rather than predicating those on the config options for the drivers, always register the platform devices so that a later built module can hook on. Also, the ethernet used to register virtual addresses in the platform data. This is wrong and so this patch changes them to physical addresses and also passes in the appropriate physical region for the PHY or Switch as appropriate.

2008-12-13[ARM] dma: correct dma_supported() implementationRussell King
dma_supported() is supposed to indicate whether the system can support the DMA mask it was passed, which depends on the maximal address which can be returned for DMA allocations.

On newer versions of the RD88F6281 board, the WAN port is connected to its own ethernet port on the CPU, via a separate PHY, whereas on older versions of the board, it is connected to one of the PHYs in the ethernet switch.

Change the halt and reboot method from gpio based to "jump to ROM IPL beginning".

It also cures the runtime warning that was printed each time the frequency was changed. Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked with the run/turbo thing.
