ARM: KVM: Correctly order SGI register entries in the cp15 array
The ICC_ASGI1R and ICC_SGI0R register entries in the cp15 array are not correctly ordered, leading to a BUG() at boot time. Move them to their natural location. Fixes: 3e8a8a50c7ef ("KVM: arm: vgic-v3: Add support for ICC_SGI0R and ICC_ASGI1R accesses") Reported-by: Florian Fainelli <f.fainelli@gmail.com> Tested-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
