arch: remove tile port

2018-03-16T09:56:03Z

The Tile architecture port was added by Chris Metcalf in 2010, and maintained until early 2018 when he orphaned it due to his departure from Mellanox, and nobody else stepped up to maintain it. The product line is still around in the form of the BlueField SoC, but no longer uses the Tile architecture. There are also still products for sale with Tile-GX SoCs, notably the Mikrotik CCR router family. The products all use old (linux-3.3) kernels with lots of patches and won't be upgraded by their manufacturers. There have been efforts to port both OpenWRT and Debian to these, but both projects have stalled and are very unlikely to be continued in the future. Given that we are reasonably sure that nobody is still using the port with an upstream kernel any more, it seems better to remove it now while the port is in a good shape than to let it bitrot for a few years first.

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
