Subject: WARN_ON after gic_reserve_range
Date: Tue, 20 Nov 2018 16:23:11 +0000	[thread overview]
Message-ID: <20181120162305.GA2088@hc> (raw)

Hi Marc,

with 4.20-rc3 I see two WARN_ON's firing on a ThunderX2 system that come from
commit 3fb68faee867 (irqchip/gic-v3-its: Register LPI tables with EFI config table).

Global efi_memreserve_root is NULL as it will only be set when early initcalls are
running, but from the backtrace the WARN_ON's are running even earlier (init_IRQ).

Am I the only one seeing this?
