The Go programming language
83824639c3
The general kernel system call interface takes 6 arguments: R0, R1, R2, R3, R4, R5. Syscall is for calls that only need 3. The amd64 and 386 versions zero the extra arg registers, but the arm version does not. func utimensat calls Syscall with 3 arguments. The kernel expects a 4th argument. That turns out to be whatever is in R3 at the time of the call. CL 137160043 changed various pieces of code and apparently changed the value left in R3 at the time of utimensat's Syscall. This causes the kernel to return EINVAL. Change linux/arm Syscall to zero R3, R4, R5, so that calls will behave deterministically, even if they pass too few arguments. Arguably, utimensat could be fixed too, but the predictable zeroing is certainly worth doing, and once done utimensat's use of Syscall is fine. Fixes arm build.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README). You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See doc/install.html for more details.
