From: Andrew Scull <redacted> [ Upstream commit f79e616f27ab6cd74deb0995a8eead3d1c9d65af ] hyp_panic() reports the address of the panic by using ELR_EL2, but this isn't a useful address when hyp_panic() is called directly. Replace such direct calls with BUG() and BUG_ON() which use BRK to trigger an exception that then goes to hyp_panic() with the correct address. Also remove the hyp_panic() declaration from the header file to avoid accidental misuse.

Same this for this patch. M. -- Without deviation from the norm, progress is not possible.
