Here's the fix:

Subject: [PATCH] mips: fix cavium-octeon build caused by memblock refactoring
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
MIPS cavium_octeon_defconfig build failed like this:
arch/mips/cavium-octeon/dma-octeon.c:205:7: error: ‘mem’ undeclared
(first use in this function); did you mean ‘sem’?
Caused by patch ("arch, drivers: replace for_each_membock() with
for_each_mem_range()")
Replacing stale 'mem->base' reference with 'start' fixes the issue.
Reported by "kernelci.org bot" <b...@kernelci.org>.
