This adds a relatively simplistic clock framework for sh. The initial goal behind this is to clean up the arch/sh/kernel/time.c mess and to get the CPU subtype-specific frequency setting and calculation code moved somewhere more sensible. This only deals with the core clocks at the moment, though it's trivial for other drivers to define their own clocks as desired.

This introduces a few changes in the way that the I/O routines are defined on SH, specifically so that things like the iomap API properly wrap through the machvec for board-specific quirks. In addition to this, the old p3_ioremap() work is converted to a more generic __ioremap() that will map through the PMB if it's available, or fall back on page tables for everything else. An alpha-like IO_CONCAT is also added so we can start to clean up the board-specific io.h mess, which will be handled in board update patches..

This moves the various IRQ controller drivers into a new subdirectory, and also extends the INTC2 IRQ handler to also deal with SH7760 and SH7780 interrupts, rather than just ST-40. The old CONFIG_SH_GENERIC has also been removed from the IRQ definitions, as new ports are expected to be based off of CONFIG_SH_UNKNOWN. Since there are plenty of incompatible machvecs, CONFIG_SH_GENERIC doesn't make sense anymore.

This extends the current SH DMA API somewhat to support a proper virtual channel abstraction, and also works to represent this through the driver model by giving each DMAC its own platform device. There's also a few other minor changes to support a few new CPU subtypes, and make TEI generation for the SH DMAC configurable.

Most of the reasons for keeping these separate before was due to hp690 discontig, and since we have a workaround for that now (abusing some shadow space so everything is magically contiguous), there's no reason to keep the targets separate.

When I removed the powermac support from arch/ppc/kernel/pci.c, I overlooked the fact that that file is used in 32-bit ARCH=powerpc builds.

This makes it possible to build kernels for PReP and/or CHRP with ARCH=ppc by removing the (non-building) powermac support. It's now also possible to select PReP and CHRP independently. Powermac users should now build with ARCH=powerpc instead of ARCH=ppc. (This does mean that it is no longer possible to build a 32-bit kernel for a G5.)

Allow gcc4 compilers to optimize unit-at-a-time. This flag enables gcc to "see" the entire C file before making optimisation decisions such as inline, which results in gcc making better decisions. One of the immediate effects of this is that static functions that are used only once now get inlined. gcc 3.4 has this flag as well, however gcc 3.x have a problem with inlining and stacks and as a result, enabling this flag there would cause excessive and unacceptable stack use. This problem is fixed in the gcc 4.x series. The x86-64 architecture already enables this feature so it's well tested already.

Seems that the CS5530A chip used in Geode GX1 systems has some crazy feature that causes SMI traps when accessing the PCI configuration space of the video device. Various GX1 BIOSes seem to use this 'feature' to hide the real BARs of the device. This patch disables these traps (in an early PCI fixup) so that Linux sees the real, physical BARs and not the virtual ones provided by the BIOS. This should allow the GX1 framebuffer driver to work on more systems that have different BIOSes as the driver no longer guesses at what the virtual BARs mean. I'm not entirely sure it the correct solution as I can neither test regular VGA console nor the X's 'cyrix' video driver so there might be some breakage there -- probably best to get some more testers before applying it.

The show_task function walks the kernel stack backchain of processes assuming that the processes are not running. Since this assumption is not correct walking the backchain can lead to an addressing exception and therefore to a kernel hang. So prevent the kernel hang (you still get incorrect results) verity that all read accesses are within the bounds of the kernel stack before performing them.
