Subject: [PATCH] mem: fix build of virtual address hinting for 32-bit
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
The initial commit doesn't build for 32-bit:
8ea9ff83 (mem: allow virtual memory address hinting)
lib/librte_eal/linuxapp/eal/eal.c: In function âeal_parse_base_virtaddrâ:
build/include/rte_common.h:133:22:
error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
RTE_PTR_ALIGN_FLOOR((typeof(ptr))RTE_PTR_ADD(ptr, (align) - 1), align)
^
RTE_PTR_ALIGN_CEIL return type is the same as what we give it as input.
So instead of casting the returned value, cast 'addr' which should be the same
as base_virtaddr.
