Subject: perfctr-2.7.9 released

Version 2.7.9 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 is a sync-up with the 2.6.11-rc1-mm1 kernel.
Reference patches for the vanilla 2.6.10 and 2.6.11-rc1
kernels are also included.

Version 2.7.9, 2005-01-16
- The kernel components now publish global information via sysfs,
  in /sys/class/perfctr/. Removed the perfctr_info() system call.
  The library has been updated accordingly. (One omission: parsing
  of files containing "cpumasks" is not yet implemented.)
- The system calls have been renumbered on all supported platforms,
  due to the removal of sys_perfctr_info() and to other system
  calls being added recently.
- Fixes forward-ported from perfctr-2.6.12:
  * On x86/x86-64, perfctr_event_codes.h now includes P4 events.
  * On x86-64 libraries will now be installed in PREFIX/lib64/,
    as per current standards, unless overridden by LIBDIR.
  * Perfex had a bug in which it interpreted all numbers as hex,
    even those without "0x" prefixes. Perfex now emits warnings
    for ambiguous numbers. To silence the warnings, (a) prefix
    hex numbers with "0x" (preferred), or (b) use the "-d" option
    to enable decimal numbers, which requires "0x" prefixes on
    hex numbers, or (c) use the "-x" option to force all numbers
    to be interpreted as hex (deprecated). The "-d" option should
    be the default, but unfortunately that would break user-level
    scripts that assumed that "0x"-less numbers are still hex.
  * Changes in examples/signal/ to handle glibc-2.3.3 on PPC32.
