Prettify link to SMTC

Ralf: Change of plan - document SMTC in the 34K page. There currently isn't enough material to justify its own page.

 Oprofile support is available at the time of this writing only in the Sourceforge Oprofile CVS repository; released versions are either lacking support for MIPS or are unusable due to bugs.  The [[R10000]], [[R12000]], [[R12000]], [[RM7000]], [[RM9000]], [[SB1|SB1 / SB1A]], [[VR5432]], [[VR5500]] processors are supported by the CVS version of the userspace tools; support for further is in the queue.

 On SGI systems it is legal and relativly common to mix different types and speeds of processors in a single system.  These processors have some significant differences in their counter implementations:
 * R10000 processors only have 2 counters
-* R12000 and R14000 processors have 4 counters
+* R12000, R14000, R16000 processors have 4 counters
 * The R10000 processor versions 2.x count the ''virtual coherency exception'' as event&nbsp;14 on counter&nbsp;0.  Version&nbsp;3.x processors change that to ''ALU/FPU completion cycles''.
-* R12000 and R14000 events differ significantly from those supported by R10000 processors.
+* R12000, R14000 and R16000 events differ significantly from those supported by R10000 processors.
 As the result oprofile will only support properly whatever the common subset of all processors in a system is.  Among the events of interest this is:

-There are further usable events (5 - 15 on counter 0, 2 - 14 on counter 14) some of which have different symbolic names on R10000 v3.x and R12000 processors in oprofile but have identical functionality, therfore are usable on mixed configurations.  Where these restrictions on mixed configurations are a possible problem attempting to restrict the configuration to a subset of identical processors may be attempted as a workaround.
