+Subject: [PATCH 006/182] clocksource: qcom: split building of legacy vs
+ multiplatform support
+
+The majority of the clocksource code for the Qualcomm platform is shared
+between newer (multiplatform) and older platforms. However there is a bit
+of code that isn't, so only build it for the appropriate config.
