First patch is worthy of a backport back to the introduction of GICv4.1, second two are intended to avoid these mess-ups in the future. Tested by kexec'ing into a new kernel on a GICv4.1 system. Oliver Upton (3): irqchip/gic-v3-its: Do not assume vPE tables are preallocated irqchip/gic-v3-its: Spin off GICv4 init into a separate function irqchip/gic-v3-its: Print the vPE table installed in redistributor drivers/irqchip/irq-gic-v3-its.c | 50 +++++++++++++++++++++----------- 1 file changed, 33 insertions(+), 17 deletions(-) base-commit: 6613476e225e090cc9aad49be7fa504e290dd33d -- 2.44.0.rc0.258.g7320e95886-goog
