[Arm-dev] [PATCH v1 20/87] arm64: gicv3: its: Increase FORCE_MAX_ZONEORDER for Cavium ThunderX

[Vadim Lomovtsev]

From: Radha Mohan Chintakuntla <rchintakuntla at cavium.com>

In case of ARCH_THUNDER, there is a need to allocate the GICv3 ITS table
which is bigger than the allowed max order. So we are forcing it only in
case of 4KB page size.
