New Revision: 326075
URL: https://svnweb.freebsd.org/changeset/base/326075

Log:
  Import the latest CloudABI definitions, v0.18.
  
  In addition to some small style fixes to the ARMv6 vDSO, this release
  includes a new vDSO that can be used for the execution of ARMv6/ARMv7
  code on 64-bit platforms.
  
  Just like for i686 on x86-64, this new vDSO is responsible for padding
  arguments and return values to 64-bit values, so that the kernel can
  easily forward system calls to the native system calls.
