NAME
       copy_to_phys - General: Copies data from a virtual address to a physical address

SYNOPSIS
       void copy_to_phys(
	       vm_offset_t virt_src,
	       vm_offset_t phys_dest,
	       unsigned int bcount );

ARGUMENTS
       Specifies the virtual address of the data to be copied.	Specifies the physical address to copy the data to.  Specifies the number of bytes
       to copy.

DESCRIPTION
       The copy_to_phys routine copies a specified amount of virtually addressed memory to physically addressed memory. The addresses reside  only
       in system memory space and not in the memory space on I/O buses.

CAUTIONS
       If any overlap exists between virt_src and phys_dest, the copy_to_phys routine panics.

RETURN VALUES
