 "Summary:
  - Fix for a boot regression introduced in v3.16-rc1,
  - Fix for a build issue in -next"

Christoph Hellwig questioned why mach_random_get_entropy should be
exported to modules, and Geert explains that random_get_entropy() is
called by at least the crypto layer and ends up using it on m68k.  On
most other architectures it just uses get_cycles() (which is typically
inlined and doesn't need exporting),

Pull parisc fixes from Helge Deller:
 "The major patch in here is one which fixes the fanotify_mark() syscall
  in the compat layer of the 64bit parisc kernel.  It went unnoticed so
  long, because the calling syntax when using a 64bit parameter in a
  32bit syscall is quite complex and even worse, it may be even
  different if you call syscall() or the glibc wrapper.  This patch
  makes the kernel accept the calling convention when called by the
  glibc wrapper.

  The other two patches are trivial and remove unused headers, #includes
  and adds the serial ports of the fastest C8000 workstation to the
  parisc-kernel internal hardware database"

On parisc we can not use the existing compat implementation for fanotify_mark()
because for the 64bit mask parameter the higher and lower 32bits are ordered
differently than what the compat function expects from big endian
architectures.

Specifically:
It finally turned out, that on hppa we end up with different assignments
of parameters to kernel arguments depending on if we call the glibc
wrapper function
 int fanotify_mark (int __fanotify_fd, unsigned int __flags,
                    uint64_t __mask, int __dfd, const char *__pathname);
or directly calling the syscall manually
 syscall(__NR_fanotify_mark, ...)

Reason is, that the syscall() function is implemented as C-function and
because we now have the sysno as first parameter in front of the other
parameters the compiler will unexpectedly add an empty paramenter in
front of the u64 value to ensure the correct calling alignment for 64bit
values.
This means, on hppa you can't simply use syscall() to call the kernel
fanotify_mark() function directly, but you have to use the glibc
function instead.

This patch fixes the kernel in the hppa-arch specifc coding to adjust
the parameters in a way as if userspace calls the glibc wrapper function
fanotify_mark().

have an issue where they edge detect and not level detect PMC overflows.

A number of places program the PMC with (0x80000000 - period_left),
where period_left can be negative. We can either fix all of these or
just ensure that period_left is always >= 1.

On POWER8 when switching to a KVM guest we set bits in MMCR2 to freeze
the PMU counters. Aside from on boot they are then never reset,
resulting in stuck perf counters for any user in the guest or host.

We now set MMCR2 to 0 whenever enabling the PMU, which provides a sane
state for perf to use the PMU counters under either the guest or the
host.

This was manifesting as a bug with ppc64_cpu --frequency:

    $ sudo ppc64_cpu --frequency
    WARNING: couldn't run on cpu 0
    WARNING: couldn't run on cpu 8
      ...
    WARNING: couldn't run on cpu 144
    WARNING: couldn't run on cpu 152
    min:    18446744073.710 GHz (cpu -1)
    max:    0.000 GHz (cpu -1)
    avg:    0.000 GHz

The command uses a perf counter to measure CPU cycles over a fixed
amount of time, in order to approximate the frequency of the machine.
The counters were returning zero once a guest was started, regardless of
weather it was still running or had been shut down.

By dumping the value of MMCR2, it was observed that once a guest is
running MMCR2 is set to 1s - which stops counters from running:

    $ sudo sh -c 'echo p > /proc/sysrq-trigger'
    CPU: 0 PMU registers, ppmu = POWER8 n_counters = 6
    PMC1:  5b635e38 PMC2: 00000000 PMC3: 00000000 PMC4: 00000000
    PMC5:  1bf5a646 PMC6: 5793d378 PMC7: deadbeef PMC8: deadbeef
    MMCR0: 0000000080000000 MMCR1: 000000001e000000 MMCRA: 0000040000000000

This is done unconditionally in book3s_hv_interrupts.S upon entering the
guest, and the original value is only save/restored if the host has
indicated it was using the PMU. This is okay, however the user of the
PMU needs to ensure that it is in a defined state when it starts using
it.

These two registers are already saved in the block above. Aside from

r8 no longer contains MMCR2, so we are clobbering the saved value with
PMC5.

MMCR2 primarily consists of counter freeze bits. So restoring the value
of PMC5 into MMCR2 will most likely have the effect of freezing
counters.

Commit 8d6f7c5a: "powerpc/powernv: Make it possible to skip the IRQHAPPENED
check in power7_nap()" added code that prevents cpus from checking for
pending interrupts just before entering sleep state, which is wrong. These
interrupts are delivered during the soft irq disabled state of the cpu.

A cpu cannot enter any idle state with pending interrupts because they will
never be serviced until the next time the cpu is woken up by some other
interrupt. Its only then that the pending interrupts are replayed. This can result
in device timeouts or warnings about this cpu being stuck.

This patch fixes ths issue by ensuring that cpus check for pending interrupts
just before entering any idle state as long as they are not in the path of split
core operations.

   - Fix for a problem introduced during the 3.14 cycle in the ACPI
     device resources management code and causing it to reject all
     resources of length 0 although some of them are actually valid
     which affects serial ports detection on a number of systems.  From
     Andy Whitcroft.

   - intel_pstate fix for a boot problem on some BayTrail-based systems
     introduced by a previous fix related to that platform during the
     3.13 cycle from Dirk Brandewie.

   - Revert of a 3.13 commit that removed the ACPI AC /proc interface
     which turns out to be still needed by some old utilities
     (kpowersave from kde 3.5.10 in particular) from Lan Tianyu.

   - cpufreq build fix for the davinci ARM platform from Prabhakar Lad
     (the breakage was introduced during the 3.10 cycle).

   - ACPI-related i915 fix preventing firmware on some Thinkpad laptops
     from setting backlight levels incorrectly during AC plug/unplug.
     From Aaron Lu.

   - Fixes for two nasty race conditions in the ACPI embedded controller
     driver that may be responsible for a number of past bug reports
     related to the EC from Lv Zhang and a fix for two memory leaks in
     error code paths in that driver from Colin Ian King.

   - Fixes for a couple of corner-case issues in the intel_pstate driver
     (all candidates for -stable) from Dirk Brandewie and Vincent Minet.

   - Fixes for two corner-case issues in the ACPI battery driver from
     Josef Gajdusek and Lan Tianyu.

   - Two new ACPI video blacklist entries for Acer TravelMate B113 and
     Dell Inspiron 5737 from Edward Lin and Martin Kepplinger"
