    powerpc: rewrite local_t using soft_irq
    
    Local atomic operations are fast and highly reentrant per CPU counters.
    Used for percpu variable updates. Local atomic operations only guarantee
    variable modification atomicity wrt the CPU which owns the data and
    these needs to be executed in a preemption safe way.
    
    Here is the design of this patch. Since local_* operations
    are only need to be atomic to interrupts (IIUC), we have two options.
    Either replay the "op" if interrupted or replay the interrupt after
    the "op". Initial patchset posted was based on implementing local_* operation
    based on CR5 which replay's the "op". Patchset had issues in case of
    rewinding the address pointor from an array. This make the slow path
    really slow. Since CR5 based implementation proposed using __ex_table to find
    the rewind addressr, this rasied concerns about size of __ex_table and vmlinux.
    
    https://lists.ozlabs.org/pipermail/linuxppc-dev/2014-December/123115.html
    
    But this patch uses, powerpc_local_irq_pmu_save to soft_disable
    interrupts (including PMIs). After finishing the "op", powerpc_local_irq_pmu_restore()
    called and correspondingly interrupts are replayed if any occured.
    
    patch re-write the current local_* functions to use arch_local_irq_disbale.
    Base flow for each function is
    
    {
    	powerpc_local_irq_pmu_save(flags)
    	load
    	..
    	store
    	powerpc_local_irq_pmu_restore(flags)
    }
    
    Reason for the approach is that, currently l[w/d]arx/st[w/d]cx.
    instruction pair is used for local_* operations, which are heavy
    on cycle count and they dont support a local variant. So to
    see whether the new implementation helps, used a modified
    version of Rusty's benchmark code on local_t.
    
    https://lkml.org/lkml/2008/12/16/450
    
    Modifications to Rusty's benchmark code:
    - Executed only local_t test
    
    Here are the values with the patch.
    
    Time in ns per iteration
    
    Local_t             Without Patch           With Patch
    
    _inc                        38              10
    _add                        38              10
    _read                       4               4
    _add_return	            38              10
    
    Currently only asm/local.h has been rewritten, and also
    the entire change is tested only in PPC64 (pseries guest)
    and PPC64 host (LE)
    
    Patch convert the inline asm implementation of the local_t
    to C. Also removed the local_dec_if_positive since there are
    no users for this.
