[PATCH v2 02/21] target/arm: fix handling of HLT semihosting in system mode

[Alex Bennée]

The check semihosting_enabled() wants to know if the guest is
currently in user mode. Unlike the other cases the test was inverted
causing us to block semihosting calls in non-EL0 modes.

Fixes: 19b26317e9 (target/arm: Honour -semihosting-config userspace=on)
