why kvm_gmem_init() needs to be called again? by mistake?
I'm sure it's a mistake.
I'm testing the gmem QEMU with this series. SW_PROTECTED_VM gets stuck
in a loop in early OVMF code due to two shared page of OVMF get zapped
and re-mapped infinitely. Removing the second call of kvm_gmem_init()
can solve the issue, though I'm not sure about the reason.
