User-Mode Linux only supports two host architectures (called $SUBARCH)
at the moment: i386 and x86_64. If you leave out the $SUBARCH on
either an i386 or

Hi,
I'm interested in cross-compiling for ARM v8, and fixing some early
papercuts to begin with; my host machine is a normal x86_64 box.
Although I managed to use Linaro's toolchain [1] to build an Aarch64
kernel, and found a suitable rootfs [2] to use it with, I am not able
to find an ARM64

Hi,
I was curiously poking around the perf tool this morning. The hacking
session resulted in two minor patches:
[1/2] is a minor non-functional cleanup of the Makefile.
[2/2] is more important: it omits printing bogus data in an edge case.
Thanks for reading.
