2009-06-27score: make irq.h definitions localArnd Bergmann
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: cleanups: dead code, 0 as pointer, shadowed variablesArnd Bergmann
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: fix function prototypesArnd Bergmann
Syscalls should return 'long' and be marked as 'asmlinkage'. Functions that are only used in a single file should be 'static'. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: add address space annotationsArnd Bergmann
Annotate the address space for pointers that are used correctly with __user and __iomem, so that sparse can better warn about incorrect casts. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-27score: add missing #includesArnd Bergmann
Files that define a global function should #include the header with its declaration to make sure that the prototypes do not diverge. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-22score: move save arg5 and arg6 instruction in front of enable_irqChen Liqin
Because enable_irq clobber r8 before arg5 was saved. modified: arch/score/kernel/entry.S Signed-off-by: Chen Liqin <liqin.chen@sunplusct.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: add prototypes for wrapped syscallsArnd Bergmann
Every system call should be declared, so this adds missing declarations for the ones we were missing so far. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: remove init_mmArnd Bergmann
init_mm is now part of the common code and not provided by the architecture any more. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: add generic sys_call_tableArnd Bergmann
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: remove __{put,get}_user_unknownArnd Bergmann
The point of these extern declarations is to provoke a link error, so an architecture must not provide a symbol for them. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2009-06-19score: unset __ARCH_WANT_IPC_PARSE_VERSIONArnd Bergmann
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2009-06-19score: Add support for Sunplus S+core architectureChen Liqin
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. Signed-off-by: Chen Liqin <liqin.chen@sunplusct.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
