Date: Wed, 24 Nov 2010 13:42:15 -0500 From: Chris Metcalf <cmetcalf@...era.com> To: linux-kernel@...r.kernel.org Subject: [PATCH] arch/tile: make glibc's sysconf(_SC_NPROCESSORS_CONF) work correctly glibc assumes that it can count /sys/devices/system/cpu/cpu* to get the number of configured cpus. For this to be valid on tile, we need to generate a "cpu" entry for all cpus, including the ones that are not currently allocated for Linux's use.
