Hi folks, Changes since v1 [1]: - Added a cover letter. (Marc) - Rebased on 7.3-rc4.
Under pKVM a vSError the guest has already taken stays pending in the host's copy of HCR_EL2, since the lazy state sync for non-protected guests stopped copying VSE back on exit. That's a 7.3-rc regression. Patch 1 reflects VSE back on every exit. Patch 2 makes the external_aborts selftest check that the SError is no longer pending once delivered: it fails on the unpatched base and passes with the fix, and also passes under nVHE and VHE. The "Confine protected VM vCPU state to EL2" series [2] carries patch 1 as its own patch 1, since its later patches change the same exit path in hyp-main.c and don't apply on a tree without the fix. It isn't part of that series: the fix lands from here, and so does the selftest, which that series doesn't carry. Based on Linux 7.3-rc4 (93f51579e7df2).
