      paravirt: refactor struct paravirt_ops into smaller pv_*_ops · 93b1eab3
      Jeremy Fitzhardinge authored
      This patch refactors the paravirt_ops structure into groups of
      functionally related ops:
      
      pv_info - random info, rather than function entrypoints
      pv_init_ops - functions used at boot time (some for module_init too)
      pv_misc_ops - lazy mode, which didn't fit well anywhere else
      pv_time_ops - time-related functions
      pv_cpu_ops - various privileged instruction ops
      pv_irq_ops - operations for managing interrupt state
      pv_apic_ops - APIC operations
      pv_mmu_ops - operations for managing pagetables
      
      There are several motivations for this:
      
      1. Some of these ops will be general to all x86, and some will be
         i386/x86-64 specific.  This makes it easier to share common stuff
         while allowing separate implementations where needed.
      
      2. At the moment we must export all of paravirt_ops, but modules only
         need selected parts of it.  This allows us to export on a case by case
         basis (and also choose which export license we want to apply).
      
      3. Functional groupings make things a bit more readable.
      
      Struct paravirt_ops is now only used as a template to generate
      patch-site identifiers, and to extract function pointers for inserting
      into jmp/calls when patching.  It is only instantiated when needed.
