[PATCH] LoongArch: KVM: Move some variable declaration to file paravirt.h
From: Bibo Mao
Date: Thu May 07 2026 - 21:30:42 EST
Some variables relative with paravirt feature are declared in header file
asm/qspinlock.h, however this file can be included only when option
CONFIG_SMP is on. There is compiling warning if CONFIG_SMP is off since
it is not declared.
Move these variable declaration to header file asm/paravirt.h to avoid
compiling warning.
Fixes: c43dce6f13fb ("LoongArch: KVM: Make vcpu_is_preempted() as a macro rather than function")
