  		allowing Go programs to use "unix" without also including "inet".
  	<li>Excluded the first page and added a guard page between I/O
  		virtual address space allocations on arm64.
! 
! 
! <!-- SMP -->
! <li>Introduced "if_cloners_lock" rwlock and used it to serialize if_clone_{create,destroy}(), avoiding multiple race conditions.
! <li>Introduced a system-wide mutex that serializes msgbuf operations.
! <li>Made <a href="https://man.openbsd.org/uvm_pagealloc.9">uvm_pagealloc(9)</a> of the physical memory allocator mp-safe.
! <li>Unlocked <a href="https://man.openbsd.org/getppid.2">getppid(2)</a>.
! <li>Introduced locking for amaps and anons, improving build performance.
! <li>Moved UNIX domain sockets out of the kernel lock, using the new "unp_lock" <a href="https://man.openbsd.org/rwlock.9">rwlock(9)</a> as solock()'s backend to protect the whole layer.
! <li>Unlocked <a href="https://man.openbsd.org/sendsyslog.2">sendsyslog(2)</a>.
! <li>Used per-CPU counter for fault and stats counters reached in uvm_fault().
! 
! 
! <!-- DRM -->
! <li>Implemented linux interval tree functions for <a href="https://man.openbsd.org/drm.4">drm(4)</a>.
! <li>Fixed <a href="https://man.openbsd.org/wsconsctl.8">wsconsctl(8)</a> display commands when using <a href="https://man.openbsd.org/drm.4">drm(4)</a> drivers on macppc.
! <li>Changed from <a href="https://man.openbsd.org/rwlock.9">rwlock(9)</a> to <a href="https://man.openbsd.org/mutex.9">mutex(9)</a> for linux rwlocks.
! <li>Fixed a panic associated with locks and <a href="https://man.openbsd.org/drm.4">drm(4)</a> on macppc with Powerbook5,6 and RV350.
! <li>Revised the initialization of the <a href="https://man.openbsd.org/drm.4">drm(4)</a> Linux emulation layer to call it only when the first drm instance attaches.
! <li>Fixed DRI3 support on <a href="https://man.openbsd.org/amdgpu.4">amdgpu(4)</a> and <a href="https://man.openbsd.org/ati.4">ati(4)</a>.
! <li>Created /dev/ drm nodes with the same names as linux to simplify libdrm and negate the need for certain ports patches.
! 
! 
! <!-- VMM/VMD -->
! 
  	<li>Prevented memory corruption or improper page access in <a
  		href="https://man.openbsd.org/vmm.4">vmm(4)</a> due to improper TLB
  		flushing for now by wiring the pages used by virtual machines.
