-Subject: [PATCH 04/32] arm: Export __boot_cpu_mode for use in Jailhouse driver
- module
-
-Onlining a CPU while Jailhouse was running sets BOOT_CPU_MODE_MISMATCH
-because the kernel detect that the CPU will now only come up in SVC
-mode. Therefore, we need to fix up the flag after disabling Jailhouse
-again.
-
-Moreover, exporting the symbol allows to use is_hyp_mode_available() in
-the driver, thus prevents us from crashing during Jailhouse activation
-when there is no hyp stub installed.
