Current firmware only allows us to send IRQs to the first processor or all processors. We currently check to see if the passed in mask is equal to the all_mask, but the firmware is only considering whether the request is for the equivalent of the possible_mask. Thus, we think the request is for some subset of CPUs and only assign IRQs to the first CPU (on systems without irqbalance running) as evidenced by /proc/interrupts. By using possible_mask instead, we account for this and proper interleaving of interrupts occurs.

BUID_HI and BUID_LO are used to pass data to call_rtas, which expects ints or u32s. But the macro doesn't cast the return, so the result is still u64. Use the upper_32_bits and lower_32_bits macros that have been added to kernel.h. Found by getting printf format errors trying to debug print the args, no actual code change for 64 bit kernels where the macros are actually used.

Enable partition migration in the kernel. To do this a new sysfs file, /sys/kernel/mobility/migration, is created. In order to initiate a migration the stream id (generated by the HMC managing the system) is written to this file. After a migration occurs, and what is the majority of this code, the device tree needs to be updated for the new system the partition is running on. This is done via the ibm,update-nodes and ibm,update-properties rtas calls which return information regarding which nodes and properties of the device tree are to be added/removed/updated.

With all the recent module loading cleanups, we've minimized the code that sits under module_mutex, fixing various deadlocks and making it possible to do most of the module loading in parallel. However, that whole conversion totally missed the rather obscure code that adds a new module to the list for BUG() handling. That code was doubly obscure because (a) the code itself lives in lib/bugs.c (for dubious reasons) and (b) it gets called from the architecture-specific "module_finalize()" rather than from generic code. Calling it from arch-specific code makes no sense what-so-ever to begin with, and is now actively wrong since that code isn't protected by the module loading lock any more. So this commit moves the "module_bug_{finalize,cleanup}()" calls away from the arch-specific code, and into the generic code - and in the process protects it with the module_mutex so that the list operations are now safe. Future fixups: - move the module list handling code into kernel/module.c where it belongs. - get rid of 'module_bug_list' and just use the regular list of modules (called 'modules' - imagine that) that we already create and maintain for other reasons.

flush_icache_range() is given virtual addresses to describe the region. It deals with these by attempting to translate them through the current set of page tables. This is fine for userspace memory and vmalloc()'d areas as they are governed by page tables. However, since the regions above 0x80000000 aren't translated through the page tables by the MMU, the kernel doesn't bother to set up page tables for them (see paging_init()). This means flush_icache_range() as it stands cannot be used to flush regions of the VM area between 0x80000000 and 0x9fffffff where the kernel resides if the data cache is operating in WriteBack mode. To fix this, make flush_icache_range() first check for addresses in the upper half of VM space and deal with them appropriately, before dealing with any range in the page table mapped area. Ordinarily, this is not a problem, but it has the capacity to make kprobes and kgdb malfunction. It should not affect gdbstub, signal frame setup or module loading as gdb has its own flush functions, and the others take place in the page table mapped area only.
