Wht about aliases? Aliases allow you go have two different physical addresses for the same page. This is useful for mapping the framebuffer on x86 (both at the pci region and at 0xa0000, the traditional ISA location). Are they useful for ia64? -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
