| Subject: IB/core: Fix build failure without hugepages |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| [ Upstream commit 74f75cda754eb69a77f910ceb5bc85f8e9ba56a5 ] |
| |
| HPAGE_SHIFT is only defined on architectures that support hugepages: |
| |
| drivers/infiniband/core/umem_odp.c: In function 'ib_umem_odp_get': |
| drivers/infiniband/core/umem_odp.c:245:26: error: 'HPAGE_SHIFT' undeclared (first use in this function); did you mean 'PAGE_SHIFT'? |
| |
| Enclose this in an #ifdef. |
| |
| Fixes: 9ff1b6466a29 ("IB/core: Fix ODP with IB_ACCESS_HUGETLB handling") |
