Loads a 32-byte cache line into L1 data cache and sets the cache line state to modified.

void _m_prefetchw( volatile const void* p );

If the line is already in the cache or if a memory fault is detected, then the intrinsic function has no effect. The variable p specifies the address of the cache line to be loaded.
