Subject: nicira-ext: Fix build problems on 64-bit systems.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dc56021df437b866c372085c195b8bdd12bd87b2;p=openvswitch

nicira-ext: Fix build problems on 64-bit systems.

Commit d2c0fe (nicira-ext: Bump number of registers to five from four.)
broke the build on 64-bit systems.  This commit fixes the problems it
introduced.
