   67: 
   68: * merge pgoyette-compat

   74: ## Release notes (top)
   75: 
   76: * Support for Aarch64 (ARM 64-bit) machines.  
   77:   The aarch64 port should work on many Allwinner machines, SBSA/SBBR compatible servers.  
   78:   It supports multiple processors, including in a big.LITTLE configuration, ACPI and UEFI.  
   79:   It uses a single kernel to support a large amount of boards with the help of ACPI+UEFI or FDT.
   80: * Updated graphical acceleration support from Linux 4.4.  
   81:   Intel graphics including Kaby Lake. Nouveau and radeon.
   82: * nvmm(4) - hardware-accelerated virtualization, currently supporting x86-SVM.  
   83:   a patched QEMU package exists that utilizes this.  
   84:   XXX make statement reflect reality at the time of the release.
   85: * KASLR - kernel address stack randomization.  
   86:   Note that the default kernel does not use this option.  
   87:   XXX maybe link for how to use it, then.
   88: * kASAN - kernel address sanitizer build option, to detect memory access violations, for x86 and aarch64.
   89: * kUBSAN - kernel undefined behaviour sanitizer.
   90: <!-- XXX kamil please list more things about micro-UBsan, MKLIBCSANITIZER, etc. -->
   91: * KLEAK - detects kernel memory leaks.
   92: * bwfm(4) - Broadcom Full-MAC wireless driver at PCI and USB (from OpenBSD)
   93: * ena(4) - Amazon.com Elastic Network Adapter (from FreeBSD)
   94: * GCC leak sanitizer support
   95: 
   96: ARM hardware support:
   97: 
   98: * Support for running on Amazon AWS ARM instances.
   99: * Support for nVidia Tegra X1 SoCs
  100: * Support for Pine64 SoCs, including pinebook
  101: <!-- XXX list more? -->

  110: * Network ATM protocol code and related drivers (midway(4))
  111: * Remote NDIS API compatibility (for running unmodified older Windows drivers)
