Hi,
I was trying to build papi 5.0.1 with the bundled libpfm and found that it
wouldn't build on 32-bit processors because one of the bit fields was too large
and didn't fit in 32-bit. I ended up working the following patch to split the
reserved field into something that would fit in 32-bits. Is there any
particular reason that field needs to be a single 58-bit quantity?
