Author: ed Date: Fri Nov 24 14:02:32 2017 New Revision: 326167 URL: https://svnweb.freebsd.org/changeset/base/326167 Log: Pick the right vDSO file/linker flags when building cloudabi32.ko on ARM64. The recently imported cloudabi_vdso_armv6_on_64bit.S should be the vDSO for 32-bit processes when being run on FreeBSD/arm64. This vDSO ensures that all system call arguments are padded to 64 bits, so that they can be used by the kernel to call into most of the native implementations directly.
