Aleksandr Rybalko 198566e04a hwpmc: Move 4 bits of mode to extend class size to 8 
Since r289025 we have had at least 5 bits class size.
Before that it was even 16 bits, but macro handling conversion between
pmcid and set of CPU, MODE, CLASS, ROWINDEX still use 4 bits class size
and 8 bits mode size.

This breaks some libpmc API methods, like pmc_capabilities.

Since we only have 4 modes and MODE field is a number (not a bitfield)
this patch moves 4 bits of mode to extend the CLASS field.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
