      ARM: OMAP: DMTimer: Optimize by adding load and start · 3fddd09e
      Richard Woodruff 提交于
      This patch optimizes the timer load and start sequence.  By combining the
      load and start a needless posted wait can be removed from the system timer
      execution path.
      
      * Before patch register writes are taking up .078% @ 500MHz during idle.

      [NET] smc91x: Make smc91x use IRQ resource trigger flags · e7b3dc7e
      Russell King 提交于
      smc91x is shared between many different platforms.  Each platform needs
      to specify the interrupt type, and in some cases the irq type depends
      on more than just the build configuration - it depends on runtime
      checks.
      
      Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
      a way for these flags to be passed via the IRQ resource itself.
      
      Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
      with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
      the low bits of PCI iomem resources correspond with the BAR flag bits.
      
      Also provide a way to configure smc91x to read the IRQ flags from the
      resource.  Once all platforms have been converted over (signified
      by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
      be removed.

      [ARM] Fix timer damage from d3d74453 · 193c3cc1
      Russell King 提交于
      Move the xtime write mode seqlock into timer_tick(), so it only
      surrounds the call to do_timer().
      
      This avoids a deadlock in update_process_times() ...
      hrtimer_get_softirq_time() which tries to get a read mode seqlock
      on xtime, thereby preventing booting.
