      s390/cpum_sf: Remove initialization of PMU event index · eaf785d5
      Hendrik Brueckner 提交于
      The git commit c719f560
      "perf: Fix and clean up initialization of pmu::event_idx" removed
      the PMU event index callback for all architectures but x86,
      remove the initialization of the event index as well.

      s390/pci: improve irq number check for msix · b19148f6
      Sebastian Ott 提交于
      s390s arch_setup_msi_irqs function ensures that we don't return with
      more irqs than the PCI architecture allows and that a single PCI
      function doesn't consume more irqs than the kernel is configured for.
      
      At least the last check doesn't help much and should take the sum of
      all irqs into account. Since that's already done by irq_alloc_desc
      we can remove this check.
      
      As for the first check we should use the value provided by the
      firmware which can be less than what the PCI architecture allows.

      s390/cmpxchg: use compiler builtins · f318a122
      Martin Schwidefsky 提交于
      The kernel build for s390 fails for gcc compilers with version 3.x,
      set the minimum required version of gcc to version 4.3.
      
      As the atomic builtins are available with all gcc 4.x compilers,
      use the __sync_val_compare_and_swap and __sync_bool_compare_and_swap
      functions to replace the complex macro and inline assembler magic
      in include/asm/cmpxchg.h. The compiler can just-do-it and generates
      better code with the builtins.
      
      While we are at it use __sync_bool_compare_and_swap for the
      _raw_compare_and_swap function in the spinlock code as well.

      ARM: dts: imx28-evk: Let i2c0 run at 100kHz · d1e61eb4
      Fabio Estevam 提交于
      Commit 78b81f46 ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues
      when doing the following sequence in loop:
      
      - Boot the kernel
      - Perform audio playback
      - Reboot the system via 'reboot' command
      
      In many times the audio card cannot be probed, which causes playback to fail.
      
      After restoring to the original i2c0 frequency of 100kHz there is no such
      problem anymore.
      
      This reverts commit 78b81f46.
