This is to push out the changes I have in order to give me a clean slate for the 2.6.8.1 UML. These changes sync up my 2.4 and 2.6 trees, and include Build cleanups, including 'linux' is now the default target, an updated defconfig, and Kconfig updates Code cleanup, including removal of unused SMP code, removal of a userspace file, more EINTR handling, more error checking Time fixes, including switching from rdtsc to gettimeofday for the real-time clock option and better handling of the host clock jumping backwards Introduction of centralized file descriptor management, allowing descriptors to be reclaimed if UML has hit the host's limit and the files can be reopened to provide access to the same object on the host Introduction of externfs, which allows host resources to be mounted as UML filesystems. externfs handles the kernel interface and plug-ins to it handle the host resources. There are two users, hostfs and humfs, both of which provide access to host directory hierarchies. humfs stores metadata separately, ala umsdos, which allows operations within the mount which would require root privileges on the host with hostfs. hostfs and humfs are still somewhat dodgy on 2.6. UML can load at 0x8048000 like every other binary when MODE_SKAS is enabled and MODE_TT is off. This makes valgrind happier, and also allows UML to have more physical memory without resorting to highmem. With STATIC_LINK disabled, the limit is ~750M, and with it enabled, the limit is ~2.75G. A good number of bugs, including some crashes were also fixed.
