From 83be4ffa1acbcd529b771f4d2e639b15e2b7957e Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Tue, 14 Aug 2012 14:47:37 -0700 Subject: [PATCH] x86/spinlocks: Fix comment in spinlock.h This comment is no longer true. We support up to 2^16 CPUs because __ticket_t is an u16 if NR_CPUS is larger than 256.
