IB/ehca: Make symbols used only in a single source file static
Allow the compiler to optimize better and generate smaller code: add/remove: 0/6 grow/shrink: 2/0 up/down: 1528/-1864 (-336) function old new delta .ehca_set_pagebuf 1344 2172 +828 .ehca_probe 2312 3012 +700 ehca_set_pagebuf_phys 24 - -24 ehca_set_pagebuf_fmr 24 - -24 ehca_init_device 24 - -24 .ehca_set_pagebuf_fmr 480 - -480 .ehca_set_pagebuf_phys 512 - -512 .ehca_init_device 800 - -800 Also this fixes warnings like: drivers/infiniband/hw/ehca/ehca_mrmw.c:2015:5: warning: symbol 'ehca_set_pagebuf_fmr' was not declared. Should it be static? Signed-off-by: Roland Dreier <rolandd@cisco.com>
