Subject: perfctr-2.6.23 released

Version 2.6.23 of perfctr, the Linux performance monitoring
counters kernel extension, is now available at the usual
place: http://www.csd.uu.se/~mikpe/linux/perfctr/2.6/

Regarding Intel's Core processors: Intel's documentation
states that each EVNTSEL has its own enable bit, just like
P4s and AMD's processors. However, testing done by the PAPI
folks indicate that Intel Core 2 has a single master enable
bit in EVNTSEL0, just like previous P6 processors. For now,
perfctr follows the traditional P6 rules for Intel Core CPUs.

Version 2.6.23, 2006-08-20
- Intel Core 2 fixes: detect Core2 processors (Model 15) and
  allow them to be used in 64-bit builds.
- Updated kernel support: 2.6.18-rc4, 2.6.17, 2.6.9-34.0.2.EL (RHEL4),
  2.4.33, 2.4.34-pre1, and 2.4.21-47.EL (RHEL3).
- The update-kernel script is now able to automatically identify
  SuSE Linux kernel versions. A SuSE kernel MUST be configured
  (".config" exists) for the identification to work.
