Fix an issue with GICv4.1 redistributor initialization after kexec,
ensuring the vPE table gets reinstalled even if the kernel is using
preallocated LPI tables.

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
