      replace nested max/min macros with {max,min}3 macro · 732eacc0
      由 Hagen Paul Pfeifer 提交于 
      Use the new {max,min}3 macros to save some cycles and bytes on the stack.
This patch substitutes trivial nested macros with their counterpart.

      mm: remove pte_*map_nested() · ece0e2b6
      由 Peter Zijlstra 提交于 
      Since we no longer need to provide KM_type, the whole pte_*map_nested()
API is now redundant, remove it.

    • P
      mm: stack based kmap_atomic() · 3e4d3af5
      由 Peter Zijlstra 提交于 
      Keep the current interface but ignore the KM_type and use a stack based
approach.

The advantage is that we get rid of crappy code like:

	#define __KM_PTE			\
		(in_nmi() ? KM_NMI_PTE : 	\
		 in_irq() ? KM_IRQ_PTE :	\
		 KM_PTE0)

and in general can stop worrying about what context we're in and what kmap
slots might be appropriate for that.

The downside is that FRV kmap_atomic() gets more expensive.

For now we use a CPP trick suggested by Andrew:

  #define kmap_atomic(page, args...) __kmap_atomic(page)

to avoid having to touch all kmap_atomic() users in a single patch.
