      powerpc: Remove check for CONFIG_SERIAL_TEXT_DEBUG · 94314290
      Paul Bolle authored
      The Kconfig symbol SERIAL_TEXT_DEBUG was removed from
      arch/powerpc/Kconfig.debug in v2.6.22. (In v2.6.27 it was also removed
      from arch/ppc/Kconfig.debug.) So the check for its macro has evaluated
      to false for over five years now. Remove that check and the few lines
      of code hidden behind it.

      powerpc: Add AT_HWCAP2 to indicate V.CRYPTO category support · dd58a092
      Benjamin Herrenschmidt authored
      The Vector Crypto category instructions are supported by current POWER8
      chips, advertise them to userspace using a specific bit to properly
      differentiate with chips of the same architecture level that might not
      have them.

       "This contains:
         - addition of the Intel MID watchdog
         - removal of W83697HF and W83697UG drivers (code was merged into
           w83627hf_wdt driver)
         - addition of Armada 375/380 SoC support

      Pull powerpc updates from Ben Herrenschmidt:
       "Here is the bulk of the powerpc changes for this merge window.  It got
        a bit delayed in part because I wasn't paying attention, and in part
        because I discovered I had a core PCI change without a PCI maintainer
        ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
        probably improve it later and I didn't want to rebase to add his ack.
      
        There is going to be a bit more next week, essentially fixes that I
        still want to sort through and test.
      
        The biggest item this time is the support to build the ppc64 LE kernel
        with our new v2 ABI.  We previously supported v2 userspace but the
        kernel itself was a tougher nut to crack.  This is now sorted mostly
        thanks to Anton and Rusty.
      
        We also have a fairly big series from Cedric that add support for
        64-bit LE zImage boot wrapper.  This was made harder by the fact that
        traditionally our zImage wrapper was always 32-bit, but our new LE
        toolchains don't really support 32-bit anymore (it's somewhat there
        but not really "supported") so we didn't want to rely on it.  This
        meant more churn that just endian fixes.
      
        This brings some more LE bits as well, such as the ability to run in
        LE mode without a hypervisor (ie. under OPAL firmware) by doing the
        right OPAL call to reinitialize the CPU to take HV interrupts in the
        right mode and the usual pile of endian fixes.
      
        There's another series from Gavin adding EEH improvements (one day we
        *will* have a release with less than 20 EEH patches, I promise!).
      
        Another highlight is the support for the "Split core" functionality on
        P8 by Michael.  This allows a P8 core to be split into "sub cores" of
        4 threads which allows the subcores to run different guests under KVM
        (the HW still doesn't support a partition per thread).
      
        And then the usual misc bits and fixes ..."
