Linux kernel stacks. Page fault processing.

A call to filemap_fault to process a page fault in user space. The function is registered as

const struct vm_operations_struct generic_file_vm_ops = {
.fault = filemap_fault,
.page_mkwrite = filemap_page_mkwrite,
.remap_pages = generic_file_remap_pages,
};
