2.6.19 new perfmon code base + libpfm + pfmon

2.6.19 new perfmon code base + libpfm + pfmon

[Stephane Eranian]

Hello,

I have released another version of the perfmon new code base packages.

There is no major updates in this version compared to 061127. This is 
a convenience release so that people can use plain 2.6.19.

The perfmon2 kernel changes are:
	- fix UP exit bug in system-wide mode where the active context
	  accounting was done incorrectly.
	- MIPS update to correct register hardware addresses (Phil Mucci)

I have also released a new libpfm, libpfm-3.2-061204 with the
following changes:
	- updated MIPS processor detection code

Also a new version of pfmon, pfmon-3.2-061204 with the following changes:
	- fix various perfmon v2.0 compatibility bugs for IA-64
	- fortify return values for read() (will Cohen)
	
Both libpfm and pfmon releases work with kernel-patch 061127 or 061204.

You can grab the new packages at our web site:

	 http://perfmon2.sf.net

Enjoy,

Some of the ptrace functions (e.g. ptrace_may_attach in perfmon_syscall.c) 
being used in the perfmon kernel patches will go away with the utrace patches:

At least for ptrace_may_attach that's not true in the lastest version
from Roland - in fact it's the last unconditional function in ptrace.c
in that version.  I suggested to him to rename and move it in my review,
though.

Sorry. I meant the function ptrace_check_attach(). -Will
