    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_disable. 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.
