The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

* This is the power management code for ATI radeon chipsets. It contains

* some dynamic clock PM enable/disable code similar to what X.org does,
|
|
* some D2-state (APM-style) sleep/wakeup code for use on some PowerMacs,
|
|
* and the necessary bits to re-initialize from scratch a few chips found
|
|
* on PowerMacs as well. The later could be extended to more platforms
|
|
* provided the memory controller configuration code be made more generic,
|
|
* and you can get the proper mode register commands for your RAMs.
|
|
* Those things may be found in the BIOS image...
