[PATCH v5 05/69] KVM: arm64: Allow preservation of the S2 SW bits

2021-11-29 Thread Marc Zyngier
The S2 page table code has a limited use the SW bits, but we are about to need them to encode some guest Stage-2 information (its mapping size in the form of the TTL encoding). Propagate the SW bits specified by the caller, and store them into the corresponding entry. Signed-off-by: Marc Zyngier
