      sparc64: Fix several bugs in memmove(). · 2077cef4

      Firstly, handle zero length calls properly.  Believe it or not there
      are a few of these happening during early boot.
      
      Next, we can't just drop to a memcpy() call in the forward copy case
      where dst <= src.  The reason is that the cache initializing stores
      used in the Niagara memcpy() implementations can end up clearing out
      cache lines before we've sourced their original contents completely.
      
      For example, considering NG4memcpy, the main unrolled loop begins like
      this:
      
           load   src + 0x00
           load   src + 0x08
           load   src + 0x10
           load   src + 0x18
           load   src + 0x20
           store  dst + 0x00
      
      Assume dst is 64 byte aligned and let's say that dst is src - 8 for
      this memcpy() call.  That store at the end there is the one to the
      first line in the cache line, thus clearing the whole line, which thus
      clobbers "src + 0x28" before it even gets loaded.
      
      To avoid this, just fall through to a simple copy only mildly
      optimized for the case where src and dst are 8 byte aligned and the
      length is a multiple of 8 as well.  We could get fancy and call
      GENmemcpy() but this is good enough for how this thing is actually
      used.

      cx82310_eth: wait for firmware to become ready · f40bff42
      Ondrej Zary authored
      
      
      When the device is powered up, some (older) firmware versions fail to work
      properly if we send commands before the boot is complete (everything is OK
      when the device is hot-plugged). The firmware indicates its ready status by
      putting the link up.
      Newer firmwares delay the first command so they don't suffer from this problem.
      They also report the link being always up.
      
      Wait for firmware to become ready (link up) before sending any commands and/or
      data.
      
      This also allows lowering CMD_TIMEOUT value to a reasonable time.
      
      Tested with 4.1.0.9 (old) and 4.1.0.30 (new) firmware versions.

      Pull power management and ACPI fixes from Rafael Wysocki:
       "These are fixes for recent regressions (PCI/ACPI resources and at91
        RTC locking), a stable-candidate powercap RAPL driver fix and two ARM
        cpuidle fixes (one stable-candidate too).
      
        Specifics:
      
         - Revert a recent PCI commit related to IRQ resources management that
           introduced a regression for drivers attempting to bind to devices
           whose previous drivers did not balance pci_enable_device() and
           pci_disable_device() as expected (Rafael J Wysocki).
      
         - Fix a deadlock in at91_rtc_interrupt() introduced by a typo in a
           recent commit related to wakeup interrupt handling (Dan Carpenter).
      
         - Allow the power capping RAPL (Running-Average Power Limit) driver
           to use different energy units for domains within one CPU package
           which is necessary to handle Intel Haswell EP processors correctly
           (Jacob Pan).
      
         - Improve the cpuidle mvebu driver's handling of Armada XP SoCs by
           updating the target residency and exit latency numbers for those
           chips (Sebastien Rannou).
      
         - Prevent the cpuidle mvebu driver from calling cpu_pm_enter() twice
           in a row before cpu_pm_exit() is called on the same CPU which
           breaks the core's assumptions regarding the usage of those
