Move mpc85xx.h to include/linux/fsl and rename it to svr.h as a common
header file. This SVR numberspace is used on some ARM chips as well as
PPC, and even to check for a PPC SVR multi-arch drivers would otherwise
need to ifdef the header inclusion and all references to the SVR symbols.

From: Arnd Bergmann
We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version
The eSDHC of T4240-R1.0-R2.0 has incorrect vender version and spec version.
Acturally the right version numbers should be VVN=0x13 and SVN = 0x1.
This patch adds the GUTS driver support for eSDHC driver to match SoC.
And fix host version to avoid that incorrect version numbers break down

Thanks Thomas for the valuable comments.
Changelog for the updated patchset:
v1->v2 - Update pvinfo.name.
v2->v3 - Address comments from Thomas G,
* Created separate function: vmware_sched_clock_setup() (patch 3/3)
* Updated commit descriptions for 1/3 and 3/3
Alexey Makhalov
Commit aa297292d708 ("x86/tsc: Enumerate SKL cpu_khz and tsc_khz via
CPUID") separated the calibration mechanisms for cpu_khz and tsc_khz.
Since the vmware hypervisor provides a constant frequency TSC to the guest,
this change can lead to divergence between the tsc and the cpu frequency
after
The default sched_clock() implementation is native_sched_clock(). It
contains code to handle non constant frequency TSCs, which creates
overhead for systems with constant frequency TSCs.
The vmware hypervisor guarantees a constant frequency TSC, so
native_sched_clock() is not required and slower
Add basic paravirt support:
1. set pv_info.name to "VMware hypervisor" to have proper boot log message
Booting paravirtualized kernel on VMware hypervisor
instead of "... on bare hardware"
2. set pv_cpu_ops.io_delay() to empty function - paravirt_nop() to
avoid vm-exits on IO

The function "perror" was called after a call of the function "fprintf"
in two if branches. So it could happen that an error message was displayed
for a failed print operation instead of the failure according to the call

fallout from CONFIG_RANDOMIZE_MEMORY=y
Misc fixes: three build
Now when we have properly working performance counters in nSIM
even with interrupt support (fix should be a part of upcoming
nSIM engineering build 2016.12-005) we may enable perf support
by default for all platforms that use nSIM for ARC cores simulation.
Note all defconfigs were regenerated

Some data were printed by two separate function calls.
Print the same data by a single call of the function "fputs" instead.

Hi Greg,
Since the couple of fixes here are not too severe, I am considering as
updates only.
Now the x86 allow CONFIG_OF to be enabled and ACPI on arm64, we have
couple of minor bugs in those configurations. The first 2 patches fixes
them. The 3rd patch is cosmetic update to help identify the
Few architectures like x86, ia64 and s390 derive the cache topology and
all the properties using a specific architected mechanism while some
other architectures like powerpc all those information id derived from
the device tree.
On ARM, both the mechanism is used. While all the cache properties
With CONFIG_OF enabled on x86, we get the following error on boot:
"
Failed to find cpu0 device node
Unable to detect cache hierarchy from DT for CPU 0
"
and the cacheinfo fails to get populated in the corresponding sysfs
entries. This is because cache_setup_of_node looks for
ARM64 enables both CONFIG_OF and CONFIG_ACPI and the firmware can pass
both ACPI tables and the device tree. Based on the kernel parameter, one
of the two will be chosen. If acpi is enabled, then device tree is not
unflattened.
Currently ARM64 platforms report:
