[PATCH hyperv-next v9 05/11] arm64: hyperv: Initialize the Virtual Trust Level field
Posted by Roman Kisel 7 months, 3 weeks ago
Various parts of the hyperv code need to know what VTL
the kernel runs at, most notably VMBus needs that to
establish communication with the host.

Initialize the Virtual Trust Level field to enable
booting in the Virtual Trust Level.
