1b84e1c81f x86, VisWS: turn into generic arch, flip over VISWS to generic arch
this is the big move: flip over VISWS to generic arch support.

From this commit on CONFIG_X86_VISWS is just another (default-disabled)
option that turns on certain quirks - no other complications.

22d5c67c5b x86, VisWS: turn into generic arch, make VisWS boot on a regular PC
first step: make the VISWS subarch boot on a regular PC.

We take various shortcuts for that. We copy the generic arch setup file over
into the VISWS setup file.

This is the only step that is not expected to boot on a real VISWS.

When an interrupt is rerouted to a different I/O APIC pin the relevant
entry of the irq_2_pin list should get updated accordingly so that
operations are performed on the correct redirection entry.

This is already done by the 32-bit variation of the code and here is a
complementing 64-bit implementation.  Should make someone's decision less
tough when merging the two. ;)

20072fd0c9 [ARM] pxa: add support for L2 outer cache on XScale3
The initial patch from Lothar, and Lennert make it into a cleaner
one, modified and tested on PXA320 by Eric Miao.

This patch moves the L2 cache operations out of proc-xsc3.S into
dedicated outer cache support code.

CACHE_XSC3L2 can be deselected so no L2 cache specific code will be
linked in, and that L2 enable bit will not be set, this applies to
the following cases:

    a. _only_ PXA300/PXA310 support included and no L2 cache wanted
    b. PXA320 support included, but want L2 be disabled

So the enabling of L2 depends on two things:

    - CACHE_XSC3L2 is selected
    - and L2 cache is present

Where the latter is only a safeguard (previous testing shows it works
OK even when this bit is turned on).

IXP series of processors with XScale3 cannot disable L2 cache for the
moment since they depend on the L2 cache for its coherent memory, so
IXP may always select CACHE_XSC3L2.

Other L2 relevant bits are always turned on (i.e. the original code
enclosed by #if L2_CACHE_ENABLED .. #endif), as they showed no side
effects. Specifically, these bits are:

   - OC bits in TTBASE register (table walk outer cache attributes)
   - LLR Outer Cache Attributes (OC) in Auxiliary Control Register
