Subject: [PATCH 43/44] tools/power turbostat: bugfix: --add u32 was printed as u64

From: Len Brown <len.brown@...el.com>

When the "u32" keyword is used with --add, it means that
the output should be truncated to 32-bits.  This was not
happening and all 64-bits were printed.

Also, when no column name was used for an added MSR,
The default column name was in deximal, eg. MSR16.
Users report that they tend to use hex MSR numbers,
so print them in hex.  To always fit into the columns,
use the syntax M0x10.  Note that the user can always
supply any column header that they want.

eg --add msr0x10,MY_TSC
