Kalesh Singh 6928bcc84b KVM: arm64: Allocate shared pKVM hyp stacktrace buffers ... In protected nVHE mode the host cannot directly access hypervisor memory, so we will dump the hypervisor stacktrace to a shared buffer with the host. The minimum size for the buffer required, assuming the min frame size of [x29, x30] (2 * sizeof(long)), is half the combined size of the hypervisor and overflow stacks plus an additional entry to delimit the end of the stacktrace. The stacktrace buffers are used later in the series to dump the nVHE hypervisor stacktrace when using protected-mode.
