The pv_time_ops structure contains a function pointer for the
"steal_clock" functionality used only by KVM and Xen on ARM. Xen on x86
uses its own mechanism to account for the "stolen" time a thread wasn't
able to run due to hypervisor scheduling.
Add support in Xen arch independent time handling for this feature by
moving it out of the arm arch into drivers/xen and remove the x86 Xen
hack.

The EFI DT parameters for bare metal are located under /chosen node,
while for Xen Dom0 they are located under /hyperviosr/uefi node. These
parameters under /chosen and /hyperviosr/uefi are not expected to appear
at the same time.
Parse these EFI parameters and initialize EFI like the way for bare
metal except the runtime services because the runtime services for Xen
Dom0 are available through hypercalls and they are always enabled. So it
sets the EFI_RUNTIME_SERVICES flag if it finds /hyperviosr/uefi node and
bails out in arm_enable_runtime_services() when EFI_RUNTIME_SERVICES
flag is set already.

It seems that recent kernels have a shorter timeout when scanning for
ethernet phys causing us to hit a timeout on boards where the phy's
regulator gets enabled just before scanning, which leads to non working
ethernet.
A 10ms startup delay seems to be enough to fix it, this commit adds a
20ms startup delay just to be safe.
This has been tested on a sun4i-a10-a1000 and sun5i-a10s-wobo-i5 board,

It seems that the wifi chip is powered by both ldo3 and ldo4 tied

Ideally we would have a proper way of modelling this (this is being

to keep these regulators always-on anyways, due to these boards
crashing when ldo3/4 get turned back on after having been turned off.

chance of reaching mainline, and yet we supported it for a good

Current errata initialization doesn't take properly revision and REVIDR
into account. Depending on the core revision, revidr bits should not be
taken into account. Errata misleadingly declares r3p3 to be error-free,
but this is not the case. Include rp3p3 in errata initialization.
Here are possible fixes defined in revidr register for r2 and r3 [1,2]:
r0p0-r2p1: No fixes applied
r2p2,r2p3:
REVIDR[4]: 798181 Moving a virtual page that is being accessed by
an active process can lead to unexpected behavior
REVIDR[9]: Not defined
r2p4,r3p0,r3p1,r3p2:
REVIDR[4]: 798181 Moving a virtual page that is being accessed by
an active process can lead to unexpected behavior
REVIDR[9]: 798181 Moving a virtual page that is being accessed by
an active process can lead to unexpected behavior
- This is an update to a previously released ECO.
r3p3:
REVIDR[4]: Reserved
REVIDR[9]: 798181 Moving a virtual page that is being accessed by
an active process can lead to unexpected behavior
- This is an update to a previously released ECO.
And here is proposed handling from the same document:
* In r3p2 and earlier versions with REVIDR[4]= 0,the full workaround is
required.
* In r3p2 and earlier versions with REVIDR[4]=1, REVIDR[9]=0, only the
portion of the workaround up to the end of step 6 is required.
* In r3p2 and earlier versions with REVIDR[4]=1, REVIDR[9]=1, no
workaround is required.
* In r3p3, if REVIDR[9]=0, only the portion of the workaround up
to the end of step 6 is required.
* In r3p3, if REVIDR[9]=1, no workaround is required.
These imply following:
REVIDR[9] set -> No WA
REVIDR[4] set, REVIDR[9] cleared -> Partial WA
Both cleared -> Full WA
Where certain bits should and should not be taken into account
depending on whether they are defined for the revision.
Although not explicitly mentioned in the errata note, REVIDR[9] set,
with REVIDR[4] cleared is valid combination which requires no WA. This
is confirmed by ARM support and errata will be updated.

KVM/ARM Fixes for v4.7-rc6:
Fixes a build issue without CONFIG_ARM_PMU and plugs pid leak on arm/arm64.
Add the device tree nodes for the Advanced Power Management Unit (APMU)
and the second Cortex-A15 CPU core.
Use the "enable-method" prop to point out that the APMU should be used
for the SMP support.

A cleanup to include the headers correctly caused another build problem:
arch/arm/mach-mvebu/kirkwood-pm.c:70:13: error: redefinition of 'kirkwood_pm_init'
arch/arm/mach-mvebu/kirkwood-pm.h:23:20: note: previous definition of 'kirkwood_pm_init' was here
The underlying issue is that kirkwood-pm.o is not actually meant to be
used when CONFIG_PM is disabled, so we should also leave it out of the
Makefile.
The same seems to be true for the PM code in MACH_MVEBU_V7, and I'm
treating it the same way here.

Add a function to check if other DT based method is available, and
if so return false to not hook up smp_ops from the machine vector.
This results in that DT-based SMP support has priority over older
C-based smp_ops code, and in case DT-based SMP support code does not
exist in the DTB then the old smp_ops code will still work as-is.

On R-Car H1 and Gen2, the SYSC interrupt registers are always configured
using hardcoded values in platform code. For R-Car Gen2, values are
provided for H2 and M2-W only, other SoCs are not yet supported, and
never will be.
Move this configuration from SoC-specific platform code to the
rcar_sysc_init() wrapper, so it can be skipped if the SYSC is configured
from DT. This would be the case not only for H1, H2, and M2-W using a
modern DTS, but also for other R-Car Gen2 SoCs not supported by the
platform code, relying purely on DT.
There is no longer a need to return the mapped register block, hence
make the function return void.

The init functions do not return any error. They behave as the following:
- panic, thus leading to a kernel crash while another timer may work and
make the system boot up correctly
or
- print an error and let the caller unaware if the state of the system
Change that by converting the init functions to return an error conforming
to the CLOCKSOURCE_OF_RET prototype.
Proper error handling (rollback, errno value) will be changed later case
by case, thus this change just return back an error or success in the init
function.

This commit makes a few slight modifications to the efi_call_virt() macro
to get it to work with function pointers that are stored in locations
other than efi.systab->runtime, and renames the macro to
efi_call_virt_pointer(). The majority of the changes here are to pull
these macros up into header files so that they can be accessed from
outside of drivers/firmware/efi/runtime-wrappers.c.
The most significant change not directly related to the code move is to
add an extra "p" argument into the appropriate efi_call macros, and use
that new argument in place of the, formerly hard-coded,
efi.systab->runtime pointer.
The last piece of the puzzle was to add an efi_call_virt() macro back into
drivers/firmware/efi/runtime-wrappers.c to wrap around the new
efi_call_virt_pointer() macro - this was mainly to keep the code from
looking too cluttered by adding a bunch of extra references to
efi.systab->runtime everywhere.
Note that I also broke up the code in the efi_call_virt_pointer() macro a
bit in the process of moving it.

This is the third version of the patchset previously sent [1]. I have
basically only rebased it on top of 4.7-rc1 tree and dropped "dm: get
rid of superfluous gfp flags" which went through dm tree. I am sending
it now because it is tree wide and chances for conflicts are reduced
considerably when we want to target rc2. I plan to send the next step
and rename the flag and move to a better semantic later during this
release cycle so we will have a new semantic ready for 4.8 merge window
hopefully.
Motivation:
While working on something unrelated I've checked the current usage of
__GFP_REPEAT in the tree. It seems that a majority of the usage is and
always has been bogus because __GFP_REPEAT has always been about costly
high order allocations while we are using it for order-0 or very small
orders very often. It seems that a big pile of them is just a
copy&paste when a code has been adopted from one arch to another.
I think it makes some sense to get rid of them because they are just
making the semantic more unclear. Please note that GFP_REPEAT is
documented as
* __GFP_REPEAT: Try hard to allocate the memory, but the allocation attempt
* _might_ fail. This depends upon the particular VM implementation.
while !costly requests have basically nofail semantic. So one could
reasonably expect that order-0 request with __GFP_REPEAT will not loop
for ever. This is not implemented right now though.
I would like to move on with __GFP_REPEAT and define a better semantic
for it.
$ git grep __GFP_REPEAT origin/master | wc -l
111
$ git grep __GFP_REPEAT | wc -l
36
So we are down to the third after this patch series. The remaining
places really seem to be relying on __GFP_REPEAT due to large allocation
requests. This still needs some double checking which I will do later
after all the simple ones are sorted out.
I am touching a lot of arch specific code here and I hope I got it right
but as a matter of fact I even didn't compile test for some archs as I
do not have cross compiler for them. Patches should be quite trivial to
review for stupid compile mistakes though. The tricky parts are usually
hidden by macro definitions and thats where I would appreciate help from
arch maintainers.
[1] http://lkml.kernel.org/r/1461849846-27209-1-git-send-email-mhocko@kernel.org
This patch (of 19):
__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations. Yet we
have the full kernel tree with its usage for apparently order-0
allocations. This is really confusing because __GFP_REPEAT is
explicitly documented to allow allocation failures which is a weaker
semantic than the current order-0 has (basically nofail).
Let's simply drop __GFP_REPEAT from those places. This would allow to
identify place which really need allocator to retry harder and formulate
a more specific semantic for what the flag is supposed to do actually.

On systems with PCI_PROBE_ONLY set, we rely on BAR assignments from
firmware. Previously we did not insert those resources into the resource
tree, so we had to skip pci_enable_resources() because it fails if
resources are not in the resource tree.
Now that we *do* insert resources even when PCI_PROBE_ONLY is set, we no
longer need the ARM-specific pcibios_enable_device(). Remove it so we
use the generic version.

We claim PCI BAR and bridge window resources in pci_bus_assign_resources(),
but when PCI_PROBE_ONLY is set, we treat those resources as immutable and
don't call pci_bus_assign_resources(), so the resources aren't put in the
resource tree.
When the resources aren't in the tree, they don't show up in /proc/iomem,
we can't detect conflicts, and we need special cases elsewhere for
PCI_PROBE_ONLY or resources without a parent pointer.
Claim all PCI BAR and window resources in the PCI_PROBE_ONLY case.
If a PCI_PROBE_ONLY platform assigns conflicting resources, Linux can't fix
the conflicts. Previously we didn't notice the conflicts, but now we will,
which may expose new failures.
