In the Linux kernel, the following vulnerability has been resolved:

LoongArch: Fix sleeping in atomic context for PREEMPT_RT

Commit bab1c299f3945ffe79 ("LoongArch: Fix sleeping in atomic context in setuptlbhandler()") changes the gfp flag from GFPKERNEL to GFPATOMIC for allocpagesnode(). However, for PREEMPT_RT kernels we can still get a "sleeping in atomic context" error:

This is because in PREEMPTRT kernels normal spinlocks are replaced by rt spinlocks and rtspinlock() will cause sleeping. Fix it by disabling NUMA optimization completely for PREEMPTRT kernels.
