There are userspace instrumentation tools that need to monitor spu context switches. This patch adds a new file called 'switch_log' to each spufs context directory that can be used to monitor the context switches. Context switch in/out and exit from spu_run are monitored after the file was first opened and can be read from it. Signed-off-by:

The powerpc kernel maintains information about logical memory blocks in the lmb.memory structure, which is initialized and updated at boot time, but not when memory is added or removed while the kernel is running. This adds a hotplug memory notifier which updates lmb.memory when memory is added or removed. This information is useful for eHEA driver to find out the memory layout and holes. NOTE: No special locking is needed for lmb_add() and lmb_remove(). Calls to these are serialized by caller. (pSeries_reconfig_chain). Signed-off-by:

Hotplug memory remove notifier for 64-bit powerpc. This gets invoked by writing to /proc/ppc64/ofdt the string "remove_node " followed by the firmware device tree pathname of the node that needs to be removed. In response, this adjusts the sections and removes sysfs entries by calling __remove_pages(). Then it calls arch-specific code to get rid of the hardware MMU mappings for the section of memory.

Add a DEBUG config setting which turns on all (most) of the debugging under platforms/pseries. To have this take effect we need to remove all the #undef DEBUG's, in various files. We leave the #undef DEBUG in platforms/pseries/lpar.c, as this enables debugging printks from the low-level hash table routines, and tends to make your system unusable. If you want those enabled you still have to turn them on by hand. Also some of the RAS code has a DEBUG block which causes a functional change, so I've keyed this off a different (non-existant) debug #define. This is only enabled if you have PPC_EARLY_DEBUG enabled also. Signed-off-by:

In pseries/lpar.c, fix some printf specifier mismatches, and add a newline to one printk. In pseries/rtasd.c add "rtasd" to some messages to make it clear where they're coming from. In pseries/scanlog.c remove the hand-rolled runtime debugging support in there. This file has been largely unchanged for eons, if we need to debug it in future we can recompile. Signed-off-by:

On pseries LPAR we can call the udbg routines, and the udbg console very early. So mark the udbg console as safe to call early in boot, and register the udbg console as soon as the udbg routines are hooked up. This allows platforms/pseries code to use printk() and pr_debug() rather than needing to call udbg_printf() directly for early debugging. This is nice because a) it's standard, b) it goes via the printk buffer, and c) you can get printk time stamps. Signed-off-by:

Currently all iSeries secondary CPUs spin directly on the cpu_start field in their paca. Make them spin on the global __secondary_hold_spinloop until after the pacas have been initialised. As Stephen Rothwell points out, this works at the moment because __secondary_hold_spinloop is being set already, but iSeries isn't looking at it :) Signed-off-by:

The xics code currently has a direct and lpar variant of xics_host_map, the only difference being which irq_chip they use. If we remember which irq_chip we're using we can combine these two routines. That also allows us to have a single irq_host_ops instead of two. Signed-off-by:

pseries_mpic_init_IRQ() implements the same logic as the xics code did to find the i8259 cascade irq. Now that we've pulled that logic out into pseries_setup_i8259_cascade() we can use it in the mpic code. Signed-off-by:
