Subject: perf: Change the is_software_event() definition

The is_software_event() definition always confuses me because its an
exclusive expression, make it an inclusive one.

Subject: perf: Make bp_len type to u64 generic across the arch

Change 'bp_len' type to __u64 to make it work across archs as
the s390 architecture watch point length can be upto 2^64.

reference:
	http://lkml.org/lkml/2010/1/25/212

This is an ABI change that is not backward compatible with
the previous hardware breakpoint info layout integrated in this
development cycle, a rebuilt of perf tools is necessary for
versions based on 2.6.33-rc1 - 2.6.33-rc6 to work with a
kernel based on this patch.
