From e0fcd1e40db4d8c5a9711f76caa4ea2362f01b26 Mon Sep 17 00:00:00 2001 From: Sebastian Sanchez Date: Wed, 8 Feb 2017 05:26:37 -0800 Subject: [PATCH] IB/hfi1: Allocate context data on memory node [ Upstream commit b448bf9a0df6093dbadac36979a55ce4e012a677 ] There are some memory allocation calls in hfi1_create_ctxtdata() that do not use the numa function parameter. This can cause cache lines to be filled over QPI.
