- pc_init is called by the operating system during boot up prior to
- any open calls being made. In the older versions of Linux (Prior
- to 2.0.0) an entry is made into tty_io.c. A pointer to the last
- memory location (from kernel space) used (kmem_start) is passed
- to pc_init. It is pc_inits responsibility to modify this value
- for any memory that the Digi driver might need and then return
- this value to the operating system. For example if the driver
- wishes to allocate 1K of kernel memory, pc_init would return
- (kmem_start + 1024). This memory (Between kmem_start and kmem_start
- + 1024) would then be available for use exclusively by the driver.
- In this case our driver does not allocate any of this kernel
- memory.
