Subject: perfctr-2.6.41 released

Version 2.6.41 of perfctr, the Linux performance monitoring
counters kernel extension, is now available at the usual
place: http://user.it.uu.se/~mikpe/linux/perfctr/2.6/

Version 2.6.41, 2010-06-08
- Extend examples/perfex/ to allow users to set up values for
  the OFFCORE_RSP MSRs on Nehalem-based processors.
- Add driver support for OFFCORE_RSP MSRs on Nehalem-based processors.
- Recognise more Nehalem-based processors (models 30, 37).
- Renamed PERFCTR_X86_INTEL_COREI7 symbolic CPU/PMU type constant
  to PERFCTR_X86_INTEL_NHLM, since it denotes the entire Nehalem
  family not just the (original) Core i7. The old constant is
  also defined for now, to not break source code compatibility.
- Correct Core i7 event setup in examples/global/ to actually
  work. It was rejected by the driver due to a copy-paste error.
- Rewrite the missing event list message in `perfex -l/-L' to
  indicate that this is a user-space library omission, not an
  issue with the driver or the hardware.
- Updated kernel support: 2.6.18-194.3.1.el5, 2.6.18-194.el5,
  2.6.18-164.15.1.el5 (RHEL5).
