[kvm-unit-tests PATCH v1 0/5] arm64: Change the default --processor to max

[Alexandru Elisei]

(CC'ing everyone from MAINTAINERS because I'm touching configure)

Vladimir sent a test for MTE [1], which didn't work on the default -cpu
model, cortex-a57, because that CPU didn't implement MTE. There were two
options to get it working:

1. Add -cpu max to the extra_params unittest parameter.
2. Make the default value for the configure --processor option 'max'.

We decided that the second option was preferable, so here it is.

The first patch might look unrelated, but when I was writing the function
to select the default processor based on the architecture I noticed that
for arm64, $arch is first equal to aarch64, then it gets changed to arm64.
My first instinct was to have it be arm64 from the start, but then I
realized that, despite the help text, --arch=aarch64 has been supported
ever since arm64 was added to kvm-unit-tests. So I decided that it might
more prudent to go with it and document it.
