This reverts commit cf07331c8827c9e9e0b4274c9b60204c18592241 which was
commit ca641bae6da977d638458e78cd1487b6160a2718 upstream.
Martin writes:
This commit breaks the kernel build because the vchiq_pagelist_info
struct is not defined in v4.9.182.
It was only added in v4.10, in commit
4807f2c0e684e907c501cb96049809d7a957dbc2.
