Subject: perfctr-2.7.3 released

Version 2.7.3 of perfctr, the Linux performance
monitoring counters driver, is now available at the usual
place: http://www.csd.uu.se/~mikpe/linux/perfctr/2.7/

Changes mostly in the area of kernel/user-space API redesign
and merging x86 and x86-64 code, as requested by LKML folks.

Version 2.7.3, 2004-05-31
- Replaced the single system call by six system calls: one
  for getting CPU information, and 5 for per-process perfctrs.
- Removed marshalling of system call parameters. Conventional
  copying is now done.
- Temporarily removed global-mode perfctrs, while the API
  to the per-process perfctrs is being redesigned.
- Changed x86-64 to use the x86 code. Simplifies maintenance,
  and, in theory, adds support for IA32e/EM64T.
- Moved detailed CPU type detection on x86 from the driver
  to the library. This is both a cleanup and a bug fix.
- Some changes to prepare the ppc32 data structures for
  potential G5/970 support, in both 32 and 64-bit kernels.
- PowerPC 750GX support added.
- Moved ppc32 #define:s to <asm-ppc/reg.h>.
- Lots of code cleanups. Converted NR_CPUS arrays to per_cpu().
  Changed spacing in if/while/switch to be "normal".
