Subject: ARM: mach-bcmring: use proper constant to identify DMA memory area
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=bfcd2ea6a40b33270564d706396f1b514a988d3c;p=~shefty%2Frdma-dev.git

ARM: mach-bcmring: use proper constant to identify DMA memory area

Using VMALLOC_END implies a presumption about the layout which is best
avoided, even if in practice this would not change much.
