Subject: perfctr-2.3.3 released

perfctr-2.3.3 is now available at the usual place:
http://www.csd.uu.se/~mikpe/linux/perfctr/

The kernel driver has three important bug fixes in this
release, and I recommend all users to upgrade immediately.

Version 2.3.3, 2001-12-31
- Added support for the 2.4.16 and 2.4.17 kernels.
- SMP bug fixed: if a process using interrupt-mode counters migrates
  from CPU1 to CPU2 and then back to CPU1, then it could incorrectly
  resume the stale state cached in CPU1.
- P6 bug fixed: when a process resumed, it could inadvertently activate
  a suspended interrupt-mode counter belonging to the previous process
  using the performance counters.
- Pentium 4 bug fixed: could fail to update the control registers on a
  context switch.
- Removed the "pmc_map[] must be the identity function" restriction
  from P6 and K7.
- Updated examples/global/global.c: added Pentium 4 support
  (preliminary, counting MIPS not FLOPS), corrected VIA C3 handling,
  and corrected 32-bit integer overflow problems affecting fast CPUs.
- Removed perfctr_evntsel_num_insns() from the library: the interface
  could not support the Pentium 4. examples/self/self.c now does the
  setup all by itself, with Pentium 4 support.
