kernel/arch/arm/include/asm/opcodes-virt.h, branch linux-4.15.y Hosts the 0x221E linux distro kernel. https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-4.15.y 2012-09-19T07:32:49Z ARM: opcodes: add __ERET/__MSR_ELR_HYP instruction encoding 2012-09-19T07:32:49Z Marc Zyngier marc.zyngier@arm.com 2012-08-09T09:43:29Z urn:sha1:b9a348cb12f3925a27fcf0a38a146b40978588d0 Enabling boot from HYP mode requires the use of some more virt-specific instructions ("eret" and "msr elr_hyp, reg"). Add the necessary encoding to asm/opcode-virt.h.

More can be added here later, as needed. Now that we have a real example of how to use the opcode injection macros properly, this patch also adds a cross-reference from the explanation in opcodes.h (since without an example, figuring out how to use the macros is not that easy).
