Subject: [PATCH 0/3] LoongArch: KVM: Add Binary Translation extension support

Loongson Binary Translation (LBT) is used to accelerate binary
translation, which contains 4 scratch registers (scr0 to scr3), x86/ARM
eflags (eflags) and x87 fpu stack pointer (ftop).

Like FPU extension, here late enabling method is used for LBT. LBT context
is saved/restored on vcpu context switch path.

Also this patch set BT capability detection, and BT register get/set
interface for userspace vmm, so that vm supports migration with BT
extension.
