* Generic semaphore implementationMatthew Wilcox2008-04-17
| | | | | | | | | | | Semaphores are no longer performance-critical, so a generic C implementation is better for maintainability, debuggability and extensibility. Thanks to Peter Zijlstra for fixing the lockdep warning. Thanks to Harvey Harrison for pointing out that the unlikely() was unnecessary.

* [XTENSA] Move string-io functions to io.c from pci.cChris Zankel2007-08-27
| | | | | | | 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 <chris@zankel.net>

* [PATCH] Xtensa: Add ktermios and minor filename fixChris Zankel2006-12-13
| | | | | | | | | | | The kernel termios (ktermios) changes were somehow missed for Xtensa. This patch adds the ktermios structure and also includes some minor file name fix that was missed in the syscall patch.
