* score: cleanups: dead code, 0 as pointer, shadowed variablesArnd Bergmann2009-06-27
| | | | | | | | 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>
* score: fix function prototypesArnd Bergmann2009-06-27
| | | | | | | 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>
* score: add address space annotationsArnd Bergmann2009-06-27
| | | | | | | | 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>
* score: add missing #includesArnd Bergmann2009-06-27
| | | | | | | | 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>

* score: add prototypes for wrapped syscallsArnd Bergmann2009-06-19
| | | | | | | 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>
* score: remove init_mmArnd Bergmann2009-06-19
| | | | | | | 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>
* score: add generic sys_call_tableArnd Bergmann2009-06-19
| | | | | | | | | | | | | | | | | | | 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>
* score: remove __{put,get}_user_unknownArnd Bergmann2009-06-19
| | | | | | | 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>
* score: unset __ARCH_WANT_IPC_PARSE_VERSIONArnd Bergmann2009-06-19
| | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 4.5.0 complains about the declaration of variables __kernel_sigreturn and __kernel_rt_sigreturn because they have type void.

| | | | | | | | | | | | | | | | | | | | arch/sh has a couple of stray markers without any users introduced in commit 3d58695edbfac785161bf282dc11fd42a483d6c9.

| * sh: pci: Initial PCI-Express support for SH7786 Urquell board.Paul Mundt2009-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds initial support for the PCI-Express module in the SH7786, particularly as it relates to the urquell platform. Presently it is only supported in root complex mode, with endpoint mode still requiring more debugging. 29/32-bit mode and lane configurations are selectable via board mode pins, and are otherwise fixed. Only 4x and 1x PCI channels are presently handled, the PCI bridge still requires additional debugging and stabilization in hardware. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The LAN9118 controller is hooked up using a 16-bit data bus, but the rsk7203 board does not swap the byte lanes as needed between the sh7203 processor and the the ethernet controller. In the processor the CS memory window is configured in 16-bit mode but the smsc911x driver is told to do 32-bit accesses to improve performance. The SMSC911X_SWAP_FIFO flag is used to tell the driver to do software byte swapping of fifo data.

A continuous loop ensues where we disable interrupts, trace the interrupt disabling, call atomic_* functions, disable interrupts, trace the interrupt disabling, etc.. The simplest solution to all this is to just convert uses of local_irq_save()/local_irq_restore() the raw_* equivalents because the raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().
