Subject: perfctr-2.7.11 released

Version 2.7.11 of perfctr, the Linux performance monitoring
counters kernel extension, is now available at the usual
place: http://www.csd.uu.se/~mikpe/linux/perfctr/2.7/

This release finishes the conversion of the system calls
to a more generic API with less dependence on struct layouts.

Reference patches for the 2.6.11 and 2.6.11-mm3 kernels
are included.

Version 2.7.11, 2005-03-14
- The kernel/user-space APIs have been converted to transmit
  control data in differently-shaped "packets" for different
  types of data. Data corresponding to CPU register images is
  transmitted as variable-length <regnr,regvalue> arrays.
  Potentially variable-sized arrays are no longer embedded in
  other API structures, but are transmitted separately. These
  changes should eliminate "binary struct" versioning problems.
- Since the library/application API had to change, the API
  structures were made compatible with perfctr-2.6.x again.
  (Reverted misguided API change in perfctr-2.7.8.)
  Added code to translate control data between the application
  format and the syscall formats.
- The system calls have been renumbered again on all platforms.
