Add two underscore characters "__" to names of BIT_* and BITSET_* macros to move them to the implementation name space and to prevent a name space pollution due to BIT_* macros in 3rd party programs with conflicting parameter signatures. These prefixed macro names are used in kernel header files to define macros in e.g. sched.h, sys/cpuset.h and sys/domainset.h. If C programs are built with either -D_KERNEL (automatically passed when building a kernel or kernel modules) or -D_WANT_FREENBSD_BITSET (or this macros is defined in the source code before including the bitset macros), then all macros are made visible with their previous names, too. E.g., both __BIT_SET() and BIT_SET() are visible with either of _KERNEL or _WANT_FREEBSD_BITSET defined. The main reason for this change is that some 3rd party sources including sched.h have been found to contain conflicting BIT_* macros. As a work-around, parts of shed.h have been made conditional and depend on _WITH_CPU_SET_T being set when sched.h is included. Ports that expect the full functionality provided by sched.h need to be built with -D_WITH_CPU_SET_T. But this leads to conflicts if BIT_* macros are defined in that program, too. This patch set makes all of sched.h visible again without this parameter being passed and without any name space pollution due to BIT_* macros becoming visible when sched.h is included. This patch set will be backported to the STABLE branches, but ports will need to use -D_WITH_CPU_SET_T as long as there are supported releases that do not contain these patches.

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.
