622a9edd91 Remove dma_cache_(wback|inv|wback_inv) functions
dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes.  Originally it was basically the raw
MIPS low level cache API exported to the entire world.  The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync.  So
remove it rsp.  turn the surviving bits back into an arch private API, as
discussed on linux-arch.

da6b003adc sh: add writesb(), readsb(), writesw() and readsw() to io.h
This patch adds inline versions of writesb(), readsb(), writesw() and
readsw() to include/asm-sh/io.h. Stolen from include/asm-avr32/io.h.

These functions are needed to compile certain device drivers such as
ax88796.

e257ad062a sh: Kill off virt_to_bus()/bus_to_virt().
Wire up ARCH_NO_VIRT_TO_BUS, and kill off the remaining users. The
dma-mapping code really wanted virt_to_phys()/phys_to_virt() anyways,
there are no inherently special bus addresses.

66c5227ecd sh: trivial build cleanups.
Several errors were spotted during building for custom config (SMP
included). Although SMP still does not compile (no ipi and
__smp_call_function) and does not work, this looks a bit cleaner.
Some other errors obtained via gcc-4.1.0 build.

e50190a834 [PATCH] Consolidate check_signature
There's nothing arch-specific about check_signature(), so move it to
<linux/io.h>.  Use a cross between the Alpha and i386 implementations as
the generic one.

This cleans up quite a lot of the PCI mess that we
currently have, and attempts to consolidate the
duplication in the SH7780 and SH7751 PCI controllers.

b66c1a3919 [PATCH] sh: I/O routine cleanups and ioremap() overhaul
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..

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
