tile: move declaration of sys_call_table to

2013-03-21T19:39:35Z

When activating syscall tracing, kernel/trace/trace_syscalls.c doesn't find sys_call_table because it includes , not . Also, looking at the other architectures, that is probably where it should be. Signed-off-by: Simon Marchi Signed-off-by: Chris Metcalf

arch/tile: eliminate pt_regs trampolines for syscalls

2012-10-23T20:23:58Z

Using the new current_pt_regs() model, we can remove some trampolines from assembly code and call directly to the C syscall implementations. rt_sigreturn() and clone() still need some assembly wrapping, but no longer are passed a pt_regs pointer. sigaltstack() and the tilepro-specific cmpxchg_badaddr() syscalls are now just straight C.

arch/tile: support header for cacheflush() syscall

2012-05-25T16:48:24Z

We already had a syscall that did some dcache flushing, but it was not used in practice. Make it MIPS compatible instead so it can do both the DCACHE and ICACHE actions. We have code that wants to be able to use the ICACHE flush mode from userspace so this change enables that. Signed-off-by: Chris Metcalf

arch/tile: Use

2010-10-14T18:34:33Z

With this change we now include into the "tile" version of the header. To take full advantage of the prototypes there, we also change our naming convention for "struct pt_regs *" syscalls so that, e.g., _sys_execve() is the "true" syscall entry, which sets the appropriate register to point to the pt_regs before calling sys_execve(). While doing this I realized I no longer needed the fork and vfork entry point stubs, since those functions aren't in the generic syscall ABI, so I removed them as well. Signed-off-by: Chris Metcalf

arch/tile: finish const-ifying sys_execve()

2010-09-15T15:16:05Z

The sys_execve() implementation was properly const-ified but not the declaration, the syscall wrappers, or the compat version. This change completes the constification process. Signed-off-by: Chris Metcalf

arch/tile: Miscellaneous cleanup changes.

2010-07-06T17:41:51Z

This commit is primarily changes caused by reviewing "sparse" and "checkpatch" output on our sources, so is somewhat noisy, since things like "printk() -> pr_err()" (or whatever) throughout the codebase tend to get tedious to read. Rather than trying to tease apart precisely which things changed due to which type of code review, this commit includes various cleanups in the code: - sparse: Add declarations in headers for globals. - sparse: Fix __user annotations. - sparse: Using gfp_t consistently instead of int. - sparse: removing functions not actually used. - checkpatch: Clean up printk() warnings by using pr_info(), etc.; also avoid partial-line printks except in bootup code. - checkpatch: Use exposed structs rather than typedefs. - checkpatch: Change some C99 comments to C89 comments. In addition, a couple of minor other changes are rolled in to this commit: - Add support for a "raise" instruction to cause SIGFPE, etc., to be raised. - Remove some compat code that is unnecessary when we fully eliminate some of the deprecated syscalls from the generic syscall ABI. - Update the tile_defconfig to reflect current config contents.
