Date: Wed, 25 Nov 2009 14:20:03 +1100 From: Paul Mackerras <paulus@...ba.org> To: Nathan Fontenot <nfont@...tin.ibm.com> Cc: linuxppc-dev@...abs.org, linux-kernel@...r.kernel.org Subject: Re: [PATCH 2/3] sysfs cpu probe/release files Nathan Fontenot writes: > Create new probe and release sysfs files to facilitate adding and removing > cpus from the system. This also creates the powerpc specific stubs to handle > the arch callouts from writes to the sysfs files. > > The creation and use of these files is regulated by the > CONFIG_ARCH_CPU_PROBE_RELEASE option so that only architectures that need the > capability will have the files created. > > Signed-off-by: Nathan Fontenot <nfont@...tin.ibm.com> > --- > arch/powerpc/Kconfig | 4 ++++ > arch/powerpc/include/asm/machdep.h | 5 +++++ > arch/powerpc/kernel/sysfs.c | 19 +++++++++++++++++++ > drivers/base/cpu.c | 32 ++++++++++++++++++++++++++++++++ Since this touches drivers/base/cpu.c, you should cc Greg KH on this patch and get an ack from him, assuming these patches are going in through the powerpc tree. > --- powerpc.orig/include/linux/cpu.h 2009-11-23 18:19:23.000000000 -0600 > +++ powerpc/include/linux/cpu.h 2009-11-24 14:30:07.000000000 -0600 > @@ -43,6 +43,10 @@ > > #ifdef CONFIG_HOTPLUG_CPU > extern void unregister_cpu(struct cpu *cpu); > +#ifdef CONFIG_ARCH_CPU_PROBE_RELEASE > +extern ssize_t arch_cpu_probe(const char *, size_t); > +extern ssize_t arch_cpu_release(const char *, size_t); > +#endif Since these are just declarations, they don't need the #ifdef around them.
