[PATCH v2 0/1] MIPS: Fix idle VS timer enqueue

[Marco Crivellari <marco.crivellari@suse.com>]

This patch aims to fix idle routine while the CPU receive an interrupt,
because __r4k_wait() only checks if TIF_NEED_RESCHED is set before
going to sleep.
The same behavior has been changed in LoongArch [1].

Code (cross) compiled successfully and I manage to test it on a VM
emulating a malta board. I ran QEMU with:

qemu-system-mips64el -M malta -m 2G -kernel vmlinux -serial stdio -drive \
file=rootfs.ext2,format=raw -append "rootwait root=/dev/sda" -cpu 5Kc

rootfs generated using buildroot (malta default configuration).
