Pull PCI fix from Bjorn Helgaas:
"Move alpha PCI IRQ map/swizzle functions out of initdata to fix
regression from PCI core IRQ mapping changes (Lorenzo Pieralisi)"
* tag 'pci-v4.14-fixes-6' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
alpha/PCI: Move pci_map_irq()/pci_swizzle() out of initdata

The introduction of {map/swizzle}_irq() hooks in the struct pci_host_bridge
allowed to replace the pci_fixup_irqs() PCI IRQ allocation in alpha arch
PCI code with per-bridge map/swizzle functions with commit 0e4c2eeb758a
("alpha/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping
hooks").
As a side effect of converting PCI IRQ allocation to the struct
pci_host_bridge {map/swizzle}_irq() hooks mechanism, the actual PCI IRQ
allocation function (ie pci_assign_irq()) is carried out per-device in
pci_device_probe() that is called when a PCI device driver is about to be
probed.
This means that, for drivers compiled as loadable modules, the actual PCI
device IRQ allocation can now happen after the system has booted so the
struct pci_host_bridge {map/swizzle}_irq() hooks pci_assign_irq() relies on
must stay valid after the system has booted so that PCI core can carry out
PCI IRQ allocation correctly.
Most of the alpha board structures pci_map_irq() and pci_swizzle() hooks
(that are used to initialize their struct pci_host_bridge equivalent
through the alpha_mv global variable - that represents the struct
alpha_machine_vector of the running kernel) are marked as
__init/__initdata; this causes freed memory dereferences when PCI IRQ
allocation is carried out after the kernel has booted (ie when loading PCI
drivers as loadable module) because when the kernel tries to bind the PCI
device to its (module) driver, the function pci_assign_irq() is called,
that in turn retrieves the struct pci_host_bridge {map/swizzle}_irq() hooks
to carry out PCI IRQ allocation; if those hooks are marked as __init
code/__initdata they point at freed/invalid memory.
Fix the issue by removing the __init/__initdata markers from all subarch
struct alpha_machine_vector.pci_map_irq()/pci_swizzle() functions (and
data).

With current SDIO CIU clock frequency (12500000Hz) DW MMC
controller fails to initialize some SD cards (which don't
support slow mode).
So increase SDIO CIU frequency from 12500000Hz to 50000000Hz by
switching from the default divisor value (div-by-8) to the
minimum possible value of the divisor (div-by-2) in HSDK platform
code.

"A fix for a regression in regard to machine check handling in KVM.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:

The new detection code for guest machine checks added a check based
on %r11 to .Lcleanup_sie to distinguish between normal asynchronous
interrupts and machine checks. But the funtion is called from the
program check handler as well with an undefined value in %r11.
The effect is that all program exceptions pointing to the SIE instruction
will set the CIF_MCCK_GUEST bit. The bit stays set for the CPU until the
next machine check comes in which will incorrectly be interpreted as a
guest machine check.
The simplest fix is to stop using .Lcleanup_sie in the program check
handler and duplicate a few instructions.

This reverts commit ce56a86e2ade45d052b3228cdfebe913a1ae7381.
There's unanticipated interaction with some boot parameters like 'mem=',
which now cause the new checks via valid_mmap_phys_addr_range() to be too
restrictive, crashing a Qemu bootup in fact, as reported by Fengguang Wu.
So while the motivation of the change is still entirely valid, we
need a few more rounds of testing to get it right - it's way too late
after -rc6, so revert it for now.

Some F14h machines have an erratum which, "under a highly specific
and detailed set of internal timing conditions" can lead to skipping
instructions and RIP corruption.
Add the fix for those machines when their BIOS doesn't apply it or
there simply isn't BIOS update for them.

On POWER9 systems, we push the VCPU context onto the XIVE (eXternal
Interrupt Virtualization Engine) hardware when entering a guest,
and pull the context off the XIVE when exiting the guest. The push
is done with cache-inhibited stores, and the pull with cache-inhibited
loads.
Testing has revealed that it is possible (though very rare) for
the stores to get reordered with the loads so that we end up with the
guest VCPU context still loaded on the XIVE after we have exited the
guest. When that happens, it is possible for the same VCPU context
to then get loaded on another CPU, which causes the machine to
checkstop.
To fix this, we add I/O barrier instructions (eieio) before and
after the push and pull operations. As partial compensation for the
potential slowdown caused by the extra barriers, we remove the eieio
instructions between the two stores in the push operation, and between
the two loads in the pull operation. (The architecture requires
loads to cache-inhibited, guarded storage to be kept in order, and
requires stores to cache-inhibited, guarded storage likewise to be
kept in order, but allows such loads and stores to be reordered with
respect to each other.)

kvmppc_gpa_to_ua() accesses KVM memory slot array via
srcu_dereference_check() and this produces warnings from RCU like below.
This extends the existing srcu_read_lock/unlock to cover that
kvmppc_gpa_to_ua() as well.
We did not hit this before as this lock is not needed for the realmode
handlers and hash guests would use the realmode path all the time;
however the radix guests are always redirected to the virtual mode
handlers and hence the warning.

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#include <linux/kvm.h>
main()
{
int fd = open("/dev/kvm", O_RDWR);
ioctl(fd, KVM_CHECK_EXTENSION, KVM_CAP_PPC_HTM);
}
This happens because when using the global KVM fd with
KVM_CHECK_EXTENSION, kvm_vm_ioctl_check_extension() gets
called with a NULL kvm argument, which gets dereferenced
in is_kvmppc_hv_enabled(). Spotted while reading the code.
Let's use the hv_enabled fallback variable, like everywhere
else in this function.

By default sparse uses the characteristics of the build
machine to infer things like the wordsize.
This is fine when doing native builds but for ARM it's,
I suspect, very rarely the case and if the build are done
on a 64bit machine we get a bunch of warnings like:
'cast truncates bits from constant value (... becomes ...)'
Fix this by adding the -m32 flags for sparse.

Some nommu systems have RAM at address 0. When vectors are not located
there, the very beginning of memory remains available for dynamic
allocations. The memblock allocator explicitly skips the first page
but the standard page allocator does not, and while it correctly returns
a non-null struct page pointer for that page, page_address() gives 0
which gets confused with NULL (out of memory) by callers despite having
plenty of free memory left.

When the second display pipeline device nodes for the A31/A31s were
added, it was not known that the TCONs could (through either DRCs)
select either backend as their input. Thus in the endpoints connecting
these components together, the endpoint IDs were set to 0, while in
fact they should have been set to 1.

The commit afece3ab9a36 ("PM / Domains: Add time accounting to various
genpd states") causes a boot regression for ux500.
The problem occurs when the ux500 machine code calls pm_genpd_init(), which
since the above change triggers a call to ktime_get(). More precisely,
because ux500 initializes PM domains in the init_IRQ() phase of the boot,
timekeeping has not yet been initialized.
Fix the problem by moving the initialization of the PM domains to after
timekeeping has been initialized.

Pull "i.MX fixes for 4.14" from Shawn Guo:
- Fix the legacy PCI interrupt numbers for i.MX7. The numbers were
wrongly coded in an inverted order than what Reference Manual tells.
It causes problem for PCI devices using legacy interrupt.

According to i.MX7D reference manual (Rev. 0.1, table 7-1, page 1221)
legacy PCI interrupt mapping is as follows:
- PCIE INT A is IRQ 122
- PCIE INT B is IRQ 123
- PCIE INT C is IRQ 124
- PCIE INT D is IRQ 125
Invert the mapping information in corresponding DT node to reflect
that.

Pull "mvebu fixes for 4.14 (part 2)" from Gregory CLEMENT
Two device tree related fixes:
- One on Armada 38x using a other compatible string for I2C in order
to cover an errata.
- One for Armada 7K/8K fixing a typo on interrupt-map property for
PCIe leading to fail PME and AER root port service initialization
And the last one for the mbus fixing the window size calculation when
it exceed 32bits

All the Armada 38x(380, 385, 388) have a silicon issue in
the I2C controller which violates the I2C repeated start timing
(errata FE-8471889).
i2c-mv64xxx driver handles this errata based on the compatible string
"marvell,mv78230-a0-i2c".
This patch activates the "marvell,mv78230-a0-i2c" compatible string
for the I2C controller on armada-38x SoC based devices.

The interrupt-map property used in the description of the Marvell
Armada 7K/8K PCIe controllers has a bogus extraneous 0 that causes the
interrupt conversion to not be done properly. This causes the PCIe PME
and AER root port service drivers to fail their initialization:
[ 5.019900] genirq: Setting trigger mode 7 for irq 114 failed (irq_chip_set_type_parent+0x0/0x30)
[ 5.028821] pcie_pme: probe of 0001:00:00.0:pcie001 failed with error -22
[ 5.035687] genirq: Setting trigger mode 7 for irq 114 failed (irq_chip_set_type_parent+0x0/0x30)
[ 5.044614] aer: probe of 0001:00:00.0:pcie002 failed with error -22
This problem was introduced when the interrupt description was
switched from using the GIC directly to using the ICU interrupt
controller. Indeed, the GIC has address-cells = <1>, which requires a
parent unit address, while the ICU has address-cells = <0>.
