      mm: remove pte_*map_nested() · ece0e2b6
      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.

      mm: stack based kmap_atomic() · 3e4d3af5
      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.

      Fix IRQ flag handling naming · df9ee292
      David Howells 提交于
      Fix the IRQ flag handling naming.  In linux/irqflags.h under one configuration,
      it maps:
      
      	local_irq_enable() -> raw_local_irq_enable()
      	local_irq_disable() -> raw_local_irq_disable()
      	local_irq_save() -> raw_local_irq_save()
      	...
      
      and under the other configuration, it maps:
      
      	raw_local_irq_enable() -> local_irq_enable()
      	raw_local_irq_disable() -> local_irq_disable()
      	raw_local_irq_save() -> local_irq_save()
      	...
      
      This is quite confusing.  There should be one set of names expected of the
      arch, and this should be wrapped to give another set of names that are expected
      by users of this facility.
      
      Change this to have the arch provide:
      
      	flags = arch_local_save_flags()
      	flags = arch_local_irq_save()
      	arch_local_irq_restore(flags)
      	arch_local_irq_disable()
      	arch_local_irq_enable()
      	arch_irqs_disabled_flags(flags)
      	arch_irqs_disabled()
      	arch_safe_halt()
      
      Then linux/irqflags.h wraps these to provide:
      
      	raw_local_save_flags(flags)
      	raw_local_irq_save(flags)
      	raw_local_irq_restore(flags)
      	raw_local_irq_disable()
      	raw_local_irq_enable()
      	raw_irqs_disabled_flags(flags)
      	raw_irqs_disabled()
      	raw_safe_halt()
      
      with type checking on the flags 'arguments', and then wraps those to provide:
      
      	local_save_flags(flags)
      	local_irq_save(flags)
      	local_irq_restore(flags)
      	local_irq_disable()
      	local_irq_enable()
      	irqs_disabled_flags(flags)
      	irqs_disabled()
      	safe_halt()
      
      with tracing included if enabled.
      
      The arch functions can now all be inline functions rather than some of them
      having to be macros.

      MIPS: Add missing #inclusions of <linux/irq.h> · ca4d3e67
      David Howells 提交于
      Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should
      really include it.  Note that this can replace #inclusions of <asm/irq.h>.
      
      This is required for the patch to sort out irqflags handling function naming to
      compile on MIPS.
      
      The problem is that these files require access to things like setup_irq() -
      which isn't available by #including <linux/interrupt.h>
