[DTrace-devel] DTrace-ized 5.6.14 pushed to linux-git and github

[Nick Alcock]

Typically, no sooner had I pushed 5.6.2 than 5.6.14 came out, and a
one-byte change to change an array into a VLA broke the patch context.
A Dtrace-ized 5.6.14 is now pushed.

Tests passed on x86-64 and AArch64 with dtrace-utils master:
see <https://github.com/oracle/dtrace-utils>. Unfortunately the need for
new translators means that no released DTrace can handle this kernel
yet (though you can copy /usr/lib64/dtrace/5.6.* to a DTrace 1.2.1
installation and it should work).

Pushed to <https://github.com/oracle/dtrace-linux-kernel>
and <https://linux-git.us.oracle.com/UEK/linux-dtrace>, as branches
with v1 in the name.

This push is of DTrace v1, with a specialized kernel module.
