323               <p>All machines with a 64bit SPARC CPU (sun4u) should be upgradable
324               without any special considerations about kernel support.</p>
325    
326               <p>sun4c CPUs are <em>no longer supported</em> in sarge.
327               The support for sun4d CPUs is in a rather unknown state since they
328               are very rare. It is possible that sun4d CPUs with an MMU work.</p>
329    
330               <p>sun4m CPUs are still supported but you need to install a newer kernel
331               version first before upgrading the system. This is because newer
332               versions of glibc use assembler instructions not available on certain
333               machines, so you need a updated kernel first that emulates the missing
334               instructions.</p>
335    
336               <p>Technically only <em>some</em> sun4m chips are affected, but as
337               glibc can't reliably detect whether a system is affected it
338               will refuse to be upgraded on any 32bit SPARC system before a
339               fixed kernel is installed.</p>
340    
341               <p>For those interested in the gory details: some of the sun4m chips,
342               produced by Cypress/ROSS, don't implement the <tt>umul</tt>
343               instruction (RT601/CY7C601, same chip, only different names).
344               They were used in the early SPARCserver 6xxMP models. Later models
345               used chips manufactured by TI. Currently we don't know if these are
346               also affected.</p>
