Hi Scott,
Platform code can call limit_zone_pfn() to set appropriate limits
for ZONE_DMA and ZONE_DMA32, and dma_direct_alloc_coherent() will
select a suitable zone based on a device's mask and the pfn limits
that platform code has configured.

Li Zhong points out an issue with our current __get_SP()
implementation. If ftrace function tracing is enabled (ie -pg
profiling using _mcount) we spill a stack frame on 64bit all the
time.
If a function calls __get_SP() and later calls a function that is
tail call optimised, we will pop the
Michael points out that __get_SP() is a pretty horrible
function name. Let's give it a better name.

called pm_power_off. The trick about this pointer is that device drivers can

The pm_power_off callback is what drivers are supposed to modify when they
