       "This patchset adds Huge Page and HUGETLBFS support for parisc"
      Honestly, the hugepage support should have gone through in the merge
      window, and is not really an rc-time fix.  But it only touches
      arch/parisc, and I cannot find it in myself to care.  If one of the
      three parisc users notices a breakage, I will point at Helge and make
      rude farting noises.

      parisc: Add Huge Page and HUGETLBFS support · 736d2169
      Helge Deller authored
      This patch adds huge page support to allow userspace to allocate huge
      pages and to use hugetlbfs filesystem on 32- and 64-bit Linux kernels.
      A later patch will add kernel support to map kernel text and data on
      huge pages.
      The only requirement is, that the kernel needs to be compiled for a
      PA8X00 CPU (PA2.0 architecture). Older PA1.X CPUs do not support
      variable page sizes. 64bit Kernels are compiled for PA2.0 by default.
      Technically on parisc multiple physical huge pages may be needed to
      emulate standard 2MB huge pages.

      Helge Deller authored
      Use the 22bit instead of the 17bit branch instruction on a 64bit kernel
      to reach the do_syscall_trace_exit function from the gateway page.
      A huge page enabled kernel may need the additional branch distance bits.

      parisc: Increase initial kernel mapping to 32MB on 64bit kernel · 332b42e4
      Helge Deller authored
      For the 64bit kernel the initially 16 MB kernel memory might become too
      small if you build a kernel with many modules built-in and with kernel
      text and data areas mapped on huge pages.
      This patch increases the initial mapping to 32MB for 64bit kernels and
      keeps 16MB for 32bit kernels.

      parisc: Initialize the fault vector earlier in the boot process. · 4182d0cd
      Helge Deller authored
      A fault vector on parisc needs to be 2K aligned.  Furthermore the
      checksum of the fault vector needs to sum up to 0 which is being
      calculated and written at runtime.
      Up to now we aligned both PA20 and PA11 fault vectors on the same 4K
      page in order to easily write the checksum after having mapped the
      kernel read-only (by mapping this page only as read-write).
      But when we want to map the kernel text and data on huge pages this
      makes things harder.
      So, simplify it by aligning both fault vectors on 2K boundries and write
      the checksum before we map the page read-only.

      parisc: Add defines for Huge page support · 1f25ad26
      Helge Deller authored
      Huge pages on parisc will have the same size as one pmd table, which
      is on a 64bit kernel 2MB on a kernel with 4K kernel page sizes, and
      on a 32bit kernel 4MB when used with 4K kernel pages.
      Since parisc does not physically supports 2MB huge page sizes, emulate
      it with two consecutive 1MB page sizes instead. Keeping the same huge
      page size as one pmd will allow us to add transparent huge page support
      later on.
      Bit 21 in the pte flags was unused and will now be used to mark a page
      as huge page (_PAGE_HPAGE_BIT).

       "These are mostly fixes and cleanups (ACPI core, PM core, cpufreq, ACPI

        intel_pstate driver commits due to a regression introduced by one of
        them plus support for Atom Airmont cores in intel_pstate (which really
        boils down to adding new frequency tables for Airmont) and additional
        turbostat updates.
         - Revert three recent intel_pstate driver commits one of which
           introduced a regression and the remaining two depend on the
           problematic one (Rafael Wysocki).
         - Fix breakage related to the recently introduced ACPI _CCA object
           support in the PCI DMA setup code (Suravee Suthikulpanit).
         - Fix up the recently introduced ACPI CPPC support to only use the
           hardware-reduced version of the PCCT structure as the only
           architecture to support it (ARM64) will only use hardware-reduced
           ACPI anyway (Ashwin Chaugule).
         - Fix a cpufreq mediatek driver build problem (Arnd Bergmann).
         - Fix the SMBus transaction handling implementation in the ACPI core
           to avoid re-entrant calls to wait_event_timeout() which makes
           intermittent boot stalls related to the Smart Battery Subsystem
           initialization go away and revert a workaround of another problem
           with the same underlying root cause (Chris Bainbridge).
         - Fix the generic wakeup interrupts framework to avoid using invalid
           IRQ numbers (Dmitry Torokhov).
         - Remove a redundant check from the ACPI EC driver (Markus Elfring).
         - Modify the intel_pstate driver so it can support more Atom flavors
           than just one (Baytrail) and add support for Atom Airmont cores
           (which require new freqnency tables) to it (Philippe Longepe).
