 1.9  26-Nov-2021  ryo - LINUX_GO_RT0_SIGNATURE for compat_linux is no longer enabled by default.
it is now defined in each arch same as the other *_SIGNATURE definitions.
- add new LINUX32_GO_RT0_SIGNATURE for compat_linux32, and is defined in amd64 and aarch64.
 1.8  25-Nov-2021  ryo add support COMPAT_LINUX32 for aarch64
 1.7  07-Jul-2010  chs many changes for COMPAT_LINUX:
- update the linux syscall table for each platform.
- support new-style (NPTL) linux pthreads on all platforms.
clone() with CLONE_THREAD uses 1 process with many LWPs
instead of separate processes.
- move the contents of sys__lwp_setprivate() into a new
lwp_setprivate() and use that everywhere.
- update linux_release[] and linux32_release[] to "2.6.18".
- adjust placement of emul fork/exec/exit hooks as needed
and adjust other emul code to match.
- convert all struct emul definitions to use named initializers.
- change the pid allocator to allow multiple pids to refer to the same proc.
- remove a few fields from struct proc that are no longer needed.
- disable the non-functional "vdso" code in linux32/amd64,
glibc works fine without it.
- fix a race in the futex code where we could miss a wakeup after
a requeue operation.
- redo futex locking to be a little more efficient.
 1.6  10-Dec-2009  matt branches: 1.6.2; 1.6.4;
Change u_long to vaddr_t/vsize_t in exec code where appropriate (mostly
involves setregs and vmcmds). Should result in no code differences.
 1.5  19-Nov-2008  ad Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime
 1.4  04-Dec-2007  dsl branches: 1.4.12; 1.4.16; 1.4.22; 1.4.24;
Remove all the __P
 1.3  23-Aug-2006  manu branches: 1.3.4; 1.3.28; 1.3.30; 1.3.36; 1.3.40;
1) Complete Linux exit_group() emulation
Members of the thread group must die without reporting to the parent and
without going to zombie stage. We do that by reparenting to init before
catching a SIGKILL. The parent will not see the child death.

The thread group leader must report the exit status, even if it exits
because of another thread calling exit_group(). We do that by storing the
exit status in struct linux_emuldata_shared, and the exit hook has the
duty of setting struct proc's p_xstat for the thread group leader.

2) For exit/fork/exec hooks, move the NPTL specific code to separate functions
that are shared between COMPAT_LINUX and COMPAT_LINUX32

3) Fix LINUX_CLONE_PARENT_SETTID semantics
 1.2  07-Aug-2006  manu Add a new signature test for linux probe function. We look for a .debuglink
section, which is specific to the Linux dynamic interpeter (yes, Linux
can execute it as a stand alone program)
 1.1  09-Feb-2006  manu branches: 1.1.2; 1.1.4; 1.1.10; 1.1.16;
Add initial (but unfinished) COMPAT_LINUX32 for amd64. This is good enough so
that the i386 license manager part of amd64 version of Fluent works.

While I'm here, add SysV IPC to COMPAT_LINUX/amd64
