[PATCH 0/3] LoongArch: Add PREEMPT_RT support

[Huacai Chen]

This series add PREEMPT_RT support for LoongArch.

With the recent printk changes, the last known road block has been
addressed. The main architectural preparation we need is selecting
HAVE_POSIX_CPU_TIMERS_TASK_WORK to allow PREEMPT_RT coexist with KVM.
Then we can also enable PREEMPT_RT as X86, ARM64 and RISC-V.

Huacai Chen(3):
 LoongArch: Reduce min_delta for the arch clockevent device.
 LoongArch: Select HAVE_POSIX_CPU_TIMERS_TASK_WORK.
 LoongArch: Allow to enable PREEMPT_RT.
