Use helpers to obtain task pid in printks (arch code)

2007-10-19T18:53:43Z

One of the easiest things to isolate is the pid printed in kernel log. There was a patch, that made this for arch-independent code, this one makes so for arch/xxx files. It took some time to cross-compile it, but hopefully these are all the printks in arch code.

Consolidate PTRACE_DETACH

2007-10-16T16:42:49Z

Identical handlers of PTRACE_DETACH go into ptrace_request(). Not touching compat code. Not touching archs that don't call ptrace_request. Signed-off-by: Alexey Dobriyan Acked-by: Christoph Hellwig Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[XTENSA] Add support for cache-aliasing

2007-08-27T20:54:16Z

Add support for processors that have cache-aliasing issues, such as the Stretch S5000 processor. Cache-aliasing means that the size of the cache (for one way) is larger than the page size, thus, a page can end up in several places in cache depending on the virtual to physical translation. The method used here is to map a user page temporarily through the auto-refill way 0 and of of the DTLB. We probably will want to revisit this issue and use a better approach with kmap/kunmap.

[XTENSA] Add kernel module support

Add kernel module support. Signed-off-by: Chris Zankel

[XTENSA] Add support for executable/non-executable feature in the mmu

2007-08-27T20:54:01Z

Newer processor versions starting with Xtensa6/LX2 support an 'executable' bit for memory pages. This bit replaces the 'valid' bit, so it must be always set to one for older processor versions. To mark a page invalid, we now set the cache-attributes to b11, which is backward compatible. Signed-off-by: Chris Zankel

[XTENSA] Fix timer instabilities.

The timer code could have missed a tick. Signed-off-by: Chris Zankel

[XTENSA] Fix fadvise64_64

2007-08-27T20:53:32Z

Xtensa passes long long arguments in a even/odd register pair, so we also need to shuffle the arguments when passed through the system call to avoid an empty argument register. Signed-off-by: Chris Zankel

[XTENSA] Move string-io functions to io.c from pci.c

2007-08-27T20:53:22Z

The string-io functions (outs{bwl}, ins{bwl}) are independent from the PCI option and should be in a separate file. Signed-off-by: Chris Zankel

[XTENSA] Move pre-initialized structures to init_task.c

2007-08-27T20:53:12Z

Move all initialization structures for the initial task to it's own file. Signed-off-by: Chris Zankel
