RDMA/mana_ib: use the correct page table index based on hardware page size
jira LE-3813
commit-author Long Li <[email protected]>
commit 9e517a8

MANA hardware uses 4k page size. When calculating the page table index,
it should use the hardware page size, not the system page size.

RDMA/mana_ib: use the correct page size for mapping user-mode doorbell page
jira LE-3813
commit-author Long Li <[email protected]>
commit 4a3b99b

When mapping doorbell page from user-mode, the driver should use the system
page size as this memory is allocated via mmap() from user-mode.
