/*
* We handle the case of the I-pipe/x86 patch series which do provide
* the early ipipe_request_tickdev() interface on top of the generic
* clock event support, but prior to its refactoring. The most
* significant changes involve an additional parameter to retrieve the
* grabbed timer frequency passed to ipipe_request_tickdev(), and a
* different prototype for mode and tick emulation callouts.
*
* This early support can be detected by testing
* CONFIG_GENERIC_CLOCKEVENTS first, since all I-pipe patches
* compatible with the generic clock event layer do define the
* ipipe_request_tickdev() service, then by testing
* __IPIPE_FEATURE_REQUEST_TICKDEV, which is only defined by I-pipe
* patches exhibiting the refactored API.
*
* THIS COMPATIBILITY SUPPORT WILL BE DEPRECATED STARTING WITH Linux
* 2.6.24. If you happen to run 2.6.22 or 2.6.23 kernels, you may want
* to upgrade your I-pipe patch to the most recent I-pipe/2.6.23
* release to date, which exhibits the refactored API.
