My patch to add install support for the powerpc selftests had a typo,
leading to the three tests in the pmu directory itself not being
installed.

This reverts commit feba40362b11341bee6d8ed58d54b896abbd9f84.

Although the principle of this change is good, the implementation has a
few issues.

Firstly we can sometimes fail to abort a syscall because r12 may have
been clobbered by C code if we went down the virtual CPU accounting
path, or if syscall tracing was enabled.

Secondly we have decided that it is safer to abort the syscall even
earlier in the syscall entry path, so that we avoid the syscall tracing
path when we are transactional.

So that we have time to thoroughly test those changes we have decided to
revert this for this merge window and will merge the fixed version in
the next window.

NB. Rather than reverting the selftest we just drop tm-syscall from
TEST_PROGS so that it's not run by default.

Pull more power management and ACPI updates from Rafael Wysocki:
 "These are fixes mostly (intel_pstate, ACPI core, ACPI EC driver,
  cpupower tool), a new CPU ID for the Intel RAPL driver and one
  intel_pstate driver improvement that didn't make it to my previous
  pull requests due to timing.

  Specifics:

   - Fix a build warning in the intel_pstate driver showing up in
     non-SMP builds (Borislav Petkov)

   - Change one of the intel_pstate's P-state selection parameters for
     Baytrail and Cherrytrail CPUs to significantly improve performance
     at the cost of a small increase in energy consumption (Kristen
     Carlson Accardi)

   - Fix a NULL pointer dereference in the ACPI EC driver due to an
     unsafe list walk in the query handler removal routine (Chris
     Bainbridge)

   - Get rid of a false-positive lockdep warning in the ACPI container
     hot-remove code (Rafael J Wysocki)

   - Prevent the ACPI device enumeration code from creating device
     objects of a wrong type in some cases (Rafael J Wysocki)

   - Add Skylake processors support to the Intel RAPL power capping
     driver (Brian Bian)

   - Drop the stale MAINTAINERS entry for the ACPI dock driver that is
     regarded as part of the ACPI core and maintained along with it now
     (Chao Yu)

   - Fix cpupower tool breakage caused by a library API change in libpci
     3.3.0 (Lucas Stach)"

While not yet documented in the Software Developer's Manual,
the data-sheet for modern Xeon states that DRAM RAPL ENERGY units
are fixed at 15.3 uJ, rather than being discovered via MSR.

Before this patch, DRAM energy on these products is over-stated by turbostat
because the RAPL units are 4x larger.

Skylake adds some additional residency counters.

Skylake supports a different mix of RAPL registers
from any previous product.

In most other ways, Skylake is like Broadwell.
