This changelog was very empty. Here is what Peter provided: When using nmi_enter() recursively, arch_nmi_enter() must also be recursion safe. In particular, it must be ensured that HCR_TGE is always set while in NMI context when in HYP mode, and be restored to it's former state when done. The current code fails this when interleaved wrong. Notably it overwrites the original hcr state on nesting. Introduce a nesting counter to make sure to store the original value.
