Subject: [PATCH] ANDROID: abi_gki_aarch64_qcom: Add vendor hook for
 shmem_alloc_page

The commit 964220d0801b ("ANDROID: shmem: vendor hook in
shmem_alloc_page") adds a vendor hook related to getting the page from
driver maintained pool first for the shmem pages. It also requires
already exported __mod_node_page_state function. Add these symbols to
the list.
