Subject: perfctr-2.6.22 released

Version 2.6.22 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/

Version 2.6.22, 2006-06-02
- Preliminary support for Intel Core (family 6 model 14) processors.
- A serious error in the x86 driver's code to identify hyper-threads
  was fixed. The driver logic is correct but it used a kernel function
  which does not provide the required behaviour in 64-bit kernels or
  older 32-bit kernels. As a result bogus data could be input to the
  hyper-thread detection code, leading to various failures.
- A change in the 2.6.16 32-bit x86 kernel caused a compilation error
  when CONFIG_PERFCTR_INIT_TESTS was enabled. Fixed this.
- Updated kernel support: 2.6.9-34.0.1 (RHEL4), 2.6.17-rc5, and
  2.4.33-pre3.
