From kernel 2.6.26rc2, SetPageReserved and ClearPageReserved changed from 
macros to inline functions, that are generated using macros (among which 
SETPAGEFLAG).

The functions were redefined because they don't exist as macros, and then 
preventing compilation.

This patch allows to compile the quickcam/qce-ga/qc-usb module on kernels 
2.6.26rc2 and later.

An other fix could use #if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,26).
