Commit 78869f0f0552 ("arm64: Extract parts of el2_setup into a macro") reorganized el2 setup in such way that virtual cpu id registers set only in nVHE, yet they used (and need) to be set irrespective VHE support. Fixes: 78869f0f0552 ("arm64: Extract parts of el2_setup into a macro") Signed-off-by: Vladimir Murzin <redacted> --- Changelog v1 -> v2 - Drop the reference to 32bit guests from commit message (per Marc) There is no upstream fix since issue went away due to code there has been reworked in 5.12: nVHE comes first, so virtual cpu id register are always set.

I've queued it up, thanks.
I don't see it, so I've added it as well... thanks, greg k-h _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
