param: convert some "on"/"off" users to strtobool

2016-03-17T22:09:34Z

This changes several users of manual "on"/"off" parsing to use strtobool. Some side-effects: - these uses will now parse y/n/1/0 meaningfully too - the early_param uses will now bubble up parse errors Signed-off-by: Kees Cook Acked-by: Heiko Carstens Acked-by: Michael Ellerman Cc: Amitkumar Karwar Cc: Andy Shevchenko Cc: Daniel Borkmann Cc: Joe Perches Cc: Kalle Valo Cc: Martin Schwidefsky Cc: Nishant Sarmukadam Cc: Rasmus Villemoes Cc: Steve French Cc: Stephen Rothwell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

powerpc/pseries: Add CPU dlpar add functionality

2015-12-17T11:41:02Z

Add the ability to hotplug add cpus via rtas hotplug events by either specifying the drc index of the CPU to add, or providing a count of the number of CPUs to add. Signed-off-by: Nathan Fontenot Signed-off-by: Michael Ellerman

powerpc/pseries: Add CPU dlpar remove functionality

2015-12-17T11:41:02Z

Add the ability to dlpar remove CPUs via hotplug rtas events, either by specifying the drc-index of the CPU to remove or providing a count of cpus to remove. To remove multiple cpus in a single request we create a list of possible DR (Dynamic Reconfiguration) cpus and their drc indexes that can be removed. We can then traverse the list remove each cpu and easily clean up in any cases of failure. Signed-off-by: Nathan Fontenot Signed-off-by: Michael Ellerman

powerpc/pseries: Update CPU hotplug error recovery

2015-12-17T11:41:02Z

Update the cpu dlpar add/remove paths to do better error recovery when a failure occurs during the add/remove operation. Signed-off-by: Nathan Fontenot Signed-off-by: Michael Ellerman

powerpc/pseries: Factor out common cpu hotplug code

2015-12-17T11:41:01Z

Re-factor the cpu hotplug code to support doing cpu hotplug completely in the kernel and using the existing sysfs probe/release interfaces. This patch pulls out pieces of existing cpu hotplug code into common routines, dlpar_cpu_add() and dlpar_cpu_remove(), to be used by both interfaces. There are no functional changes introduced.

powerpc/pseries: Consolidate CPU hotplug code to hotplug-cpu.c

2015-12-17T11:41:01Z

No functional changes, this patch is simply a move of the cpu hotplug code from pseries/dlpar.c to pseries/hotplug-cpu.c. This is in an effort to consolidate all of the cpu hotplug code in a common place. Signed-off-by: Nathan Fontenot Signed-off-by: Michael Ellerman

powerpc/pseries: Use rtas_call_unlocked() in pseries hotplug

2015-12-17T11:40:55Z

Avoid open coding the logic by using rtas_call_unlocked(). Signed-off-by: Michael Ellerman

powerpc: Replace cpumask_weight(cpu_possible_mask) with num_possible_cpus()

2015-01-23T03:02:51Z

num_possible_cpus() is just a shorthand for it. Signed-off-by: Emil Medve Signed-off-by: Michael Ellerman

of/reconfig: Always use the same structure for notifiers

2014-11-24T22:25:03Z

The OF_RECONFIG notifier callback uses a different structure depending on whether it is a node change or a property change. This is silly, and not very safe. Rework the code to use the same data structure regardless of the type of notifier. Signed-off-by: Grant Likely Cc: Benjamin Herrenschmidt Cc: Rob Herring Cc: Pantelis Antoniou Cc:

powerpc/pseries: Make CPU hotplug path endian safe

2014-10-15T00:25:59Z

- ibm,rtas-configure-connector should treat the RTAS data as big endian. - Treat ibm,ppc-interrupt-server#s as big-endian when setting smp_processor_id during hotplug. Signed-off-by: Bharata B Rao Signed-off-by: Thomas Falcon Acked-by: Nathan Fontenot Signed-off-by: Michael Ellerman
