From 4d658d13c90f14cf3510ca15cafe2f4aa9e23d64 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Wed, 24 Nov 2010 13:42:15 -0500 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.
