score: add old syscall support

2009-08-30T04:33:30+00:00

score: cleanups: dead code, 0 as pointer, shadowed variables

2009-06-27T13:16:16+00:00

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.

score: fix function prototypes

2009-06-27T13:14:58+00:00

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

score: add address space annotations

2009-06-27T13:09:52+00:00

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

score: add missing #includes

2009-06-27T13:09:46+00:00

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

score: add generic sys_call_table

2009-06-19T12:10:33+00:00

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.
