Revision 7ae11635ec90072083503c6b6485cdffe46203b3 authored by Jisheng Zhang on 29 March 2021, 18:16:24 UTC, committed by Palmer Dabbelt on 16 April 2021, 04:32:40 UTC
Current riscv's kprobe handlers are run with both preemption and
interrupt enabled, this violates kprobe requirements. Fix this issue
by keeping interrupts disabled for BREAKPOINT exception.
Fixes: c22b0bcb1dd0 ("riscv: Add kprobes supported")
