Subject: perfctr-2.7.6 released

Version 2.7.6 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 2.6.9-rc4-mm1 kernel.
A reference patch for the vanilla 2.6.9 kernel is included.

Version 2.7.6, 2004-10-19
- Added preliminary overflow interrupt support for PPC32.
  There are currently several limitations of this feature:
  * Only enabled on MPC7455 processors. Will later be enabled
    on all G4 processors except 7400 and early 7410.
  * Either none or all of the "PMCj" group counters (i.e.,
    all but PMC1) must be marked as interrupt-mode counters.
    This is because PPC32 doesn't provide per-counter interrupt
    enable/disable control. User-space should ignore overflow
    signals from counters it isn't interested in.
- Corrected the PPC32 driver's handling of MMCR0 changes due
  to use of the FCECE or TRIGGER control flags.
- Fixed a synchronisation error in the interface between
  the per-process counters driver and the low-level drivers.
  The error triggered warnings in DEBUG_SPINLOCK_SLEEP-
  enabled kernels.
