# Commit e78a7614f3876 ("idle: Prevent late-arriving interrupts from # disrupting offline") changes arch_cpu_idle_dead to be called with # interrupts disabled, which triggers the WARN in pnv_smp_cpu_kill_self. # # Fix this by fixing up irq_happened after hard disabling, rather than # requiring there are no pending interrupts, similarly to what was done # done until commit 2525db04d1cc5 ("powerpc/powernv: Simplify lazy IRQ # handling in CPU offline"). # # Fixes: e78a7614f3876 ("idle: Prevent late-arriving interrupts from disrupting offline") # Reported-by: Paul Mackerras # Signed-off-by: Nicholas Piggin # [mpe: Add unexpected_mask rather than checking for known bad values, # change the WARN_ON() to a WARN_ON_ONCE()] # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20191022115814.22456-1-npiggin@gmail.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version #
