b5022df4c2 score: remove init_mm
init_mm is now part of the common code and not provided
by the architecture any more.

f673c032ed score: add generic sys_call_table
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.

78229db4c4 score: remove __{put,get}_user_unknown
The point of these extern declarations is to provoke a link
error, so an architecture must not provide a symbol for them.

72ea372341 score: unset __ARCH_WANT_IPC_PARSE_VERSION
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.

6bc9a3966f score: Add support for Sunplus S+core architecture
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.
