score does not need multiple zero pages, because it does not
suffer from cache aliasing problems, so simplify that code.
Also make some functions static and include the appropriate
header files.

Some internal definitions of the interrupt controller are
only needed in irq.c, so move them out of the global irq.h
header. Also add proper __iomem annotations for sparse.

A few smaller issues found by sparse, some code that was
never used, two instances of '0' instead of 'NULL' and
local variables shadowing another one.

Syscalls should return 'long' and be marked as 'asmlinkage'.
Functions that are only used in a single file should be 'static'.

Annotate the address space for pointers that are used
correctly with __user and __iomem, so that sparse
can better warn about incorrect casts.

Files that define a global function should #include the
header with its declaration to make sure that the prototypes
do not diverge.

Because enable_irq clobber r8 before arg5 was saved.

Every system call should be declared, so this adds missing
declarations for the ones we were missing so far.

init_mm is now part of the common code and not provided
by the architecture any more.

This adds back a sys_call_table to the score architecture, which
got lost in the conversion to the generic unistd.h file.
It's rather worrying that the code got submitted without a
system call table, which evidently means that it got zero
testing.

Since the system call table has a different layout from the old
one (which was modeled after the mips-o32 one), I also try to
fix the entry.S path to use it. In the modified calling conventions,
all system call arguments are passed as registers r4 through r9,
instead of r4 through r7 plus stack for the fifth and sixth argument.

This matches what other architectures to when they normally pass
arguments on the stack.

The point of these extern declarations is to provoke a link
error, so an architecture must not provide a symbol for them.

This really should not be needed. The change for not changing
the IPC code for every new architecture just went into 2.6.31,
so we can skip it now.

This is the complete set of new arch Score's files for linux.
Score instruction set support 16bits, 32bits and 64bits instruction,
Score SOC had been used in game machine and LCD TV.
