Based on recent thread on linux-arch (some weeks ago) I
decided to check how much work was required to build sparc32
with STRICT_MM_TYPECHECKS enabled.
The resulting binary (checked srmmu.o) was to my suprise smaller with
STRICT_MM_TYPECHECKS defined, than without.
As I have no working gear to test sparc32 bits at for the moment,
I did not enable STRICT_MM_TYPECHECKS - but was tempeted to do so.

The base is always the same so no need to use a variable for this.

Use _AC() in definition of PAGE_SIZE so the same definition
can be used in C and assembler.
Also use PAGE_SIZE in definition of THREAD_SIZE.
This commit kill the following comment:
"I have my suspicions... -DaveM"
I did not find any clue what this referred to anyway.

It doesn't account for phys_base like it should, fix by using
page_to_pfn().
While we're here, make virt_to_page() use pfn_to_page() as well, so we
consistently use the asm/memory-model.h abstractions instead of
open-coding memory model assumptions.

The current asm-generic/page.h only contains the get_order
function, and asm-generic/uaccess.h only implements
unaligned accesses. This renames the file to getorder.h
and uaccess-unaligned.h to make room for new page.h
and uaccess.h file that will be usable by all simple
(e.g. nommu) architectures.

While doing some easy cleanups on the sparc code I noticed that the
CONFIG_SUN4 code seems to be worse than the rest - there were some
"I don't know how it should work, but the current code definitely cannot
work." places.
And while I have seen people running Linux on machines like a
SPARCstation 5 a few years ago I don't recall having seen sun4
machines, even less ones running Linux.

The majority of this patch was created by the following script:
***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***
The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.
