Subject: arm/arm64: kvm: Disable branch profiling in HYP code

From: Julien Thierry <[email protected]>

commit f9b269f3098121b5d54aaf822e0898c8ed1d3fec upstream.

When HYP code runs into branch profiling code, it attempts to jump to unmapped memory, causing a HYP Panic.

Disable the branch profiling for code designed to run at HYP mode.
