[ Upstream commit 6a437208cb942a2dd98f7e1c3fd347ed3d425ffc ]
Starting with FEAT_WFXT in ARMv8.7, the TI field in the ISS that is reported on a WFx trap is expanded by one bit to allow the description of WFET and WFIT.
Special care is taken to exclude the WFxT bit from the mask used to match WFI so that it also matches WFIT when trapped from EL0.

Please do not backport this patch. It achieves nothing on its own, and the kernel isn't broken without it.
I'll drop this and the other ones you've pointed out.
Also, please do not AUTOSEL KVM/arm64 patches that are not tagged with a Cc stable.
Happily!
