The pull request is correct. For most patches (except the truly 
gargantuan ones) I attach or inline so that patchwork detects it as a 
patch which makes the release maintainers job easier.

----------------
#!/bin/bash
full_version=`uname -r`

# Removing flavour from version i.e. generic or server.
flavour_abi=${full_version#*-}
flavour=${flavour_abi#*-}
version=${full_version%-$flavour}
perf="perf_$version"

if ! which "$perf" > /dev/null; then
     echo "$perf not found" >&2
     echo "You may need to install linux-tools-$version" >&2
     exit 2
fi

exec "$perf" "$@"
----------------

I find the variable naming a bit confusing. 
'version=${full_version%-$flavour}' doesn't do what it purports, though 
it does work. Perhaps some clarification?
