A strange behaviour is observed when comparing PCI hotplug in QEMU, between
x86 and pseries. If you consider the following steps:
- start a VM
- add a PCI device via the QEMU monitor before the rtasd has started (for
example starting the VM in paused state, or hotplug during FW or boot
loader)
- resume the VM execution
The x86 kernel detects the PCI device, but the pseries one does not.
This happens because the rtasd kernel worker is currently started under
device_initcall, while PCI probing happens earlier under subsys_initcall.
As a consequence, if we have a pending RTAS event at boot time, a message
is printed and the event is dropped.
This patch moves all the initialization of rtasd to arch_initcall, which is
run before subsys_call: this way, logging_enabled is true when the RTAS
event pops up and it is not lost anymore.
The proc fs bits stay at device_initcall because they cannot be run before
fs_initcall.

Intel Penwell is one of the first SoCs in Intel MID series. It has slightly
older version of PWRMU IP, though it is compatible with one found on Intel
Tangier. Since we are not using (yet) any advanced stuff in the driver we may
safely re-use what it's done for Intel Tangier for now.
Extend PWRMU driver to support Intel Penwell by adding PCI ID and re-using
existing ->set_initial_state() function.

Intel MID platforms (Moorestown, Medfield, Clovertrail, Merrifield) are
sharing the code in the intel_mid_pci.c module. There is no need to
power off specific Moorestown devices after the following commit:
5823d0893ec2 ("x86/platform/intel-mid: Add Power Management Unit driver")
... because the condition in mrfld_power_off_dev() is true for any platform
from the above list.
Remove duplicate power off certain devices on Intel Moorestown and rename
the affected functions to show that they are applied to any of Intel MID
platforms.

Pull ACPI fixes from Rafael Wysocki:
"All of these fix recent regressions in ACPICA, in the ACPI PCI IRQ
management code and in the ACPI AML debugger.
Specifics:
- Fix a lock ordering issue in ACPICA introduced by a recent commit
that attempted to fix a deadlock in the dynamic table loading code
which in turn appeared after changes related to the handling of
module-level AML also made in this cycle (Lv Zheng).
- Fix a recent regression in the ACPI IRQ management code that may
cause PCI drivers to be unable to register an IRQ if that IRQ
happens to be shared with a device on the ISA bus, like the
parallel port, by reverting one commit entirely and restoring the
previous behavior in two other places (Sinan Kaya).
- Fix a recent regression in the ACPI AML debugger introduced by the
commit that removed incorrect usage of IS_ERR_VALUE() from multiple
places (Lv Zheng)"

When we enter an exception, the current address limit should not apply
to the exception context: if the exception context wishes to access
kernel space via the user accessors (eg, perf code), it must explicitly
request such access.

If we take an exception while at EL1, the exception handler inherits
the original context's addr_limit and PSTATE.UAO values. To be consistent
always reset addr_limit and PSTATE.UAO on (re-)entry to EL1. This
prevents accidental re-use of the original context's addr_limit.
Based on a similar patch for arm from Russell King.

Track generated header files which aren't already in genhdr-y, alongside
generic-y wrappers in the */include/generated/[uapi/]asm/ directories.
Currently only x86 generates extra headers in these directories, for the
purposes of enumerating system calls for different ABIs, and xen
hypercalls.
This will allow the asm-generic wrapper handling code to remove stale
wrappers when files are removed from generic-y, without also removing
these headers which are generated separately.

is no rush for these for the -rc cycle, these can wait for the

Merge "Reset controller changes for v4.8, part 3" from Philipp Zabel:
- change request API to be more explicit about the difference between
exclusive and shared resets (the former guarantee the reset line is
asserted immediately when reset_control_assert is called, the latter
are refcounted and do not guarantee this).
- add Hisilicon hi6220 media subsystem reset controller support
- add TI SYSCON based reset controller support

The domain/PHB field of PCI addresses has its value obtained from a
global variable, incremented each time a new domain (represented by
struct pci_controller) is added on the system. The domain addition
process happens during boot or due to PHB hotplug add.
As recent kernels are using predictable naming for network interfaces,
the network stack is more tied to PCI naming. This can be a problem in
hotplug scenarios, because PCI addresses will change if devices are
removed and then re-added. This situation seems unusual, but it can
happen if a user wants to replace a NIC without rebooting the machine,
for example.
This patch changes the way PCI domain values are generated: now, we use
device-tree properties to assign fixed PHB numbers to PCI addresses
when available (meaning pSeries and PowerNV cases). We also use a bitmap
to allow dynamic PHB numbering when device-tree properties are not
used. This bitmap keeps track of used PHB numbers and if a PHB is
released (by hotplug operations for example), it allows the reuse of
this PHB number, avoiding PCI address to change in case of device remove
and re-add soon after. No functional changes were introduced.

- Fix the I2C address and supply line names for the AK8974
- Sets up the interrupt lines to the different components as they
actually are connected, I was confused for some time by the fact
that several lines were connected with <NM> 0 Ohm resistors, which
means NOT MOUNTED and is thus not 0 Ohm at all but infinite ohms,
i.e. not connected at all.

The original patch was to add compatible string for Hi3519 soc
and do some cleanup.
Since the generic machine entry could meet most of the cases,
so I did a further cleanup to reuse it and just keep one machine
entry that needs map_io here.
