The zap_vma_ptes() is declared but not defined on NOMMU kernels, causing a
link error for the newly added uverbs code:
drivers/infiniband/core/uverbs_main.o: In function `uverbs_user_mmap_disassociate':
uverbs_main.c:(.text+0x114c): undefined reference to `zap_vma_ptes'
drivers/infiniband/core/uverbs_main.o: In function `rdma_umap_open':
uverbs_main.c:(.text+0x53c): undefined reference to `zap_vma_ptes'
Since all user access for all of our drivers depend on remapping pages to
user space disable USER_ACCESS when there is no mmu.
Fixes: 5f9794dc94 ("RDMA/ucontext: Add a core API for mmaping driver IO memory")

Userspace InfiniBand access support. This enables the

kernel side of userspace verbs and the userspace
|
|
communication manager (CM). This allows userspace processes
|
|
to set up connections and directly access InfiniBand
|
|
hardware for fast-path operations. You will also need
|
|
libibverbs, libibcm and a hardware driver library from

The UCM module has known security flaws, which no one is
|
|
interested to fix. The user-space part of this code was
|
|
dropped from the upstream a long time ago.

|
This option is DEPRECATED and planned to be removed.
