PS20: 
FYI, one thing clang-format seems to handle poorly is consecutive macros that have indented bit definitions. For example, after running `clang-format-15 -i -style=file` with this patch applied, I see things like:
-#define MSR_FEATURE_CONFIG              0x13c
-#define   FEATURE_CONFIG_LOCK           BIT(0)
+#define MSR_FEATURE_CONFIG  0x13c
+#define FEATURE_CONFIG_LOCK BIT(0)

In this case the indentation before FEATURE_CONFIG_LOCK makes it more obvious that it's a field within MSR_FEATURE_CONFIG. I'm not sure if there's a way to make clang-format follow that convention, but thought it's worth mentioning.
