The PCIe programming sequence in TRM suggests CLKSTCTRL of PCIe should be
set to SW_WKUP. There are no issues when CLKSTCTRL is set to HW_AUTO in RC
mode. However in EP mode, the host system is not able to access the
MEMSPACE and setting the CLKSTCTRL to SW_WKUP fixes it.

kvm_make_all_requests() provides a synchronization that waits until all
kicked VCPUs have acknowledged the kick. This is important for
KVM_REQ_MMU_RELOAD as it prevents freeing while lockless paging is
underway.
This patch adds the synchronization property into all requests that are
currently being used with kvm_make_all_requests() in order to preserve
the current behavior and only introduce a new framework. Removing it
from requests where it is not necessary is left for future patches.

Some operations must ensure that the guest is not running with stale
data, but if the guest is halted, then the update can wait until another
event happens. kvm_make_all_requests() currently doesn't wake up, so we
can mark all requests used with it.
First 8 bits were arbitrarily reserved for request numbers.
Most uses of requests have the request type as a constant, so a compiler
will optimize the '&'.
An alternative would be to have an inline function that would return
whether the request needs a wake-up or not, but I like this one better
even though it might produce worse assembly.

The PCI bus specification (rev 3.0, 3.2.5 "Transaction Ordering and
Posting") defines rules for PCI configuration space transactions ordering
and posting, that state that configuration writes have to be non-posted
transactions.
Current ioremap interface on ARM provides mapping functions that provide
"bufferable" writes transactions (ie ioremap uses MT_DEVICE memory type)
aka posted writes, so PCI host controller drivers have no arch interface to
remap PCI configuration space with memory attributes that comply with the
PCI specifications for configuration space.
Implement an ARM specific pci_remap_cfgspace() interface that allows to map
PCI config memory regions with MT_UNCACHED memory type (ie strongly ordered
- non-posted writes), providing a remap function that complies with PCI
specifications for config space transactions.

When entering the hyp stub implemented in the idmap, we try to
be mindful of the fact that we could be running a Thumb-2 kernel
by adding 1 to the address we compute. Unfortunately, the assembler
also knows about this trick, and has already generated an address
that has bit 0 set in the litteral pool.
Our superfluous correction ends up confusing the CPU entierely,
as we now branch to the stub in ARM mode instead of Thumb, and on
a possibly unaligned address for good measure. From that point,
nothing really good happens.
The obvious fix in to remove this stupid target PC correction.

The support for dynamic ftrace with CONFIG_DEBUG_RODATA involves
overriding the weak arch_ftrace_update_code() with a variant which makes
the kernel text writable around the patching.
This override was however added under the CONFIG_OLD_MCOUNT ifdef, and
CONFIG_OLD_MCOUNT is only enabled if frame pointers are enabled.
This leads to non-functional dynamic ftrace (ftrace triggers a
WARN_ON()) when CONFIG_DEBUG_RODATA is enabled and CONFIG_FRAME_POINTER
is not.
Move the override out of that ifdef and into the CONFIG_DYNAMIC_FTRACE
ifdef where it belongs.

To cope with the variety in ARM architectures and configurations, the
pagetable attributes for kernel memory are generated at runtime to match
the system the kernel finds itself on. This calculated value is stored
in pgprot_kernel.
However, when early fixmap support was added for ARM (commit
a5f4c561b3) the attributes used for mappings were hard coded because
pgprot_kernel is not set up early enough. Unfortunately, when fixmap is
used after early boot this means the memory being mapped can have
different attributes to existing mappings, potentially leading to
unpredictable behaviour. A specific problem also exists due to the hard
coded values not include the 'shareable' attribute which means on
systems where this matters (e.g. those with multiple CPU clusters) the
cache contents for a memory location can become inconsistent between
CPUs.
To resolve these issues we change fixmap to use the same memory
attributes (from pgprot_kernel) that the rest of the kernel uses. To
enable this we need to refactor the initialisation code so
build_mem_type_table() is called early enough. Note, that relies on early
param parsing for memory type overrides passed via the kernel command
line, so we need to make sure this call is still after
parse_early_params().

Fix potential races in kvm_psci_vcpu_on() by taking the kvm->lock
mutex. In general, it's a bad idea to allow more than one PSCI_CPU_ON
to process the same target VCPU at the same time. One such problem
that may arise is that one PSCI_CPU_ON could be resetting the target
vcpu, which fills the entire sys_regs array with a temporary value
including the MPIDR register, while another looks up the VCPU based
on the MPIDR value, resulting in no target VCPU found. Resolves both
races found with the kvm-unit-tests/arm/psci unit test.

be usable on the arm64 H5 DTSI, that shares almost everything with the H3
but the CPU cores.
We then have patches to support the H5 boards on top.

The phy is necessary for the dwc2 controllers driving the usb ports
on all arm32 Rockchip socs. Both the dwc2 as well as usb downstream
drivers (mass-storage as well as usb networking) are already built-in,
so only the phy is missing to allow booting from usb-devices without

These are all your garden variety fixes for ARM platforms. Most visible issue

We found out that HW checksum generation only works from AST2500
onward. This disables it on AST2400 and removes the "no-hw-checksum"
properties in the device-trees. The problem we had wasn't related
to NC-SI.
Also rework the logic testing for that property so it can be used
to disable HW checksum generation and checking regardless of whether
NC-SI is used or not in case other variants out there need this.

Recently most nodes got labels to make them referenceable. The USB 3.0
nodes as well as the nodes for the SATA controllers were left out,
rectify the omission.
The labels "sataX" are already used by some boards for the SATA ports,
therefore use "ahciX" to label the SATA controller nodes.
To avoid potential confusion by labeling an USB3.0 controller "usb2" use
usb3_X as labels. This also coincides with the node names themselves
(usb@xxxxx vs usb3@xxxxx).

The PHYs embedded in the switch direct there interrupts through the
switch interrupt controllers. Now that devel C has its switch
interrupts connected to the SoC, the PHY interrupts can be used by
phylib. Explicitly include MDIO nodes in the switch device tree nodes,
and link the PHY interrupts back to the switch interrupt
controller. Also, link the ports to the PHYs on the MDIO bus.

According to the reference manuals, both imx50/imx53 SOC seem to share
the same eSDHC controller, especially the section on "Multi-block Read"
mentioned in commit 361b848202 ("mmc: sdhci-esdhc-imx: fix multiblock
reads on i.MX53") is identical for both SOC.
Hence, let imx50 use imx53-esdhc.

All currently supported i.MX25-based machines use phy_type = "utmi" and
dr_mode = "otg". So this seems to be a sensible default.
This also doesn't hurt out-of-tree machines because up to now they had
to specify these two properties in the machine.dts which still takes
precedence by just overwriting the defaults added here.

Pull ARM fixes from Russell King:
"A number of ARM fixes:
- prevent oopses caused by dma_get_sgtable() and declared DMA
coherent memory
- fix boot failure on nommu caused by ID_PFR1 access
- a number of kprobes fixes from Jon Medhurst and Masami Hiramatsu"
* 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm:
ARM: 8665/1: nommu: access ID_PFR1 only if CPUID scheme
ARM: dma-mapping: disallow dma_get_sgtable() for non-kernel managed memory
arm: kprobes: Align stack to 8-bytes in test code
arm: kprobes: Fix the return address of multiple kretprobes
arm: kprobes: Skip single-stepping in recursing path if possible
arm: kprobes: Allow to handle reentered kprobe on single-stepping
Now that we support both timers and PMU reporting interrupts
to userspace, we can advertise this support.

When not using an in-kernel VGIC, but instead emulating an interrupt
controller in userspace, we should report the PMU overflow status to
that userspace interrupt controller using the KVM_CAP_ARM_USER_IRQ
feature.

If you're running with a userspace gic or other interrupt controller
(that is no vgic in the kernel), then you have so far not been able to
use the architected timers, because the output of the architected
timers, which are driven inside the kernel, was a kernel-only construct
between the arch timer code and the vgic.
This patch implements the new KVM_CAP_ARM_USER_IRQ feature, where we use a
side channel on the kvm_run structure, run->s.regs.device_irq_level, to
always notify userspace of the timer output levels when using a userspace
irqchip.
This works by ensuring that before we enter the guest, if the timer
output level has changed compared to what we last told userspace, we
don't enter the guest, but instead return to userspace to notify it of
the new level. If we are exiting, because of an MMIO for example, and
the level changed at the same time, the value is also updated and
userspace can sample the line as it needs. This is nicely achieved
simply always updating the timer_irq_level field after the main run
loop.
Note that the kvm_timer_update_irq trace event is changed to show the
host IRQ number for the timer instead of the guest IRQ number, because
the kernel no longer know which IRQ userspace wires up the timer signal
to.
Also note that this patch implements all required functionality but does
not yet advertise the capability.

We have 2 modes for dealing with interrupts in the ARM world. We can
either handle them all using hardware acceleration through the vgic or
we can emulate a gic in user space and only drive CPU IRQ pins from
there.
Unfortunately, when driving IRQs from user space, we never tell user
space about events from devices emulated inside the kernel, which may
result in interrupt line state changes, so we lose out on for example
timer and PMU events if we run with user space gic emulation.
Define an ABI to publish such device output levels to userspace.

When the compressed image needs to be relocated to avoid being
overwritten by the decompression process, we need to relocate
the hyp vectors as well so that we can find them once the
decompression has taken effect.
For that, we perform the following calculation:
u32 v = __hyp_get_vectors();
v += offset;
__hyp_set_vectors(v);
But we're guaranteed that the initial value of v as returned by
__hyp_get_vectors is always __hyp_stub_vectors, because we have
just set it by calling __hyp_stub_install.
So let's remove the use of __hyp_get_vectors, and directly use
__hyp_stub_vectors instead.
