[ Upstream commit 05c4e2721d7af0df7bc1378a23712a0fd16947b5 ]
commit ba9196d2e005 ("MIPS: Make DIEI support as a config option")
use CPU_HAS_DIEI to indicate whether di/ei is implemented correctly,
without this patch, "local_irq_disable" from entry.S in 3A1000
(with buggy di/ei) lose protection of commit e97c5b609880 ("MIPS:
Make irqflags.h functions preempt-safe for non-mipsr2 cpus")
Fixes: ba9196d2e005 ("MIPS: Make DIEI support as a config option")
