Subject: perfctr-2.7.5 released

Version 2.7.5 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/

This release mainly fixes kernel locking problems in
the initial implementation of perfctr inheritance.

This is a syncup with the development code in the
2.6.8.1-mm1 kernel. For that kernel you only need the
user-space components, but there is also a patch
allowing this to be added to the vanilla 2.6.8.1 kernel.

Version 2.7.5, 2004-08-18
- Some x86 driver cleanups.
- Minor fixes to the driver init testing code on x86-64.
- Fixed update-kernel script to use 'head' in a POSIX
  compliant way.
- Updated user-space library and examples to handle P4 Model 3
  in 64-bit mode.
- Fixed an unforseen kernel synchronisation error with the
  newly added perfctr inheritance code. The error triggered
  warnings in CONFIG_DEBUG_SPINLOCK_SLEEP-enabled kernels.
- Fixed another kernel locking rule violation in the new
  perfctr inheritance code.
- Fixed an x86 driver initialisation bug which could cause
  it to disable the NMI watchdog prematurely.
