Day" Date: Fri, 3 May 2013 06:45:48 -0400 Subject: include/linux/cpu.h: Update comments to reflect reality Two minor changes to comments: * Remove reference to drivers/base/sys.c, removed in 0a962657. * CPUs are now exported by sysfs via devices/system/cpu.

For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. This removes all the uses of the __cpuinit macros from C files in the core kernel directories (kernel, init, lib, mm, and include) that don't really have a specific maintainer.
