To enable other irqchip declarations beyond the lx_emul generic code base,
make the ARM specific initialization routine public.

Reintroduce:
USB Attached SCSI devices might expose a bulk-only interface
as fall-back at interface 0 and alternate setting 0. This commit
allows for probing all alternate settings of the active interface
to be able to use such devices.
The configuration was extended so that in case the device interface
is known beforehand the driver can be configured accordingly.
Additionally:
Perform configuration reset upon sessions close in order to bring USB
device to a well defined state.
fixes#4494
Instead of allowing the client to set a caching attribute
in the io_mem() call of the device interface, which was
only used to decide in between of the memory being
write-combined or not, remove it from the API.
Instead use the information delivered by the devices ROM,
whether memory from a PCI BAR is prefetchable or not,
to decide whether it is mapped write-combined or not.

* Remove wrapper for legacy x86 platform API
* Move PCI configuration space quirks to corresponding driver
(pc_usb_host_drv, pc_wifi_drv, pc_intel_fb_drv)
* Adapt driver test run-scripts to changed configuration

Instead of having a generic "virt_qemu" board use "virt_qemu_<arch>" in
order to have a clean distinction between boards. Current supported
boards are "virt_qemu_arm_v7a", "virt_qemu_arm_v8a", and
"virt_qemu_riscv".
issue #4034
Skip SET_CONFIGURATION requests if the device already has the selected
config as active config. This workaround prevents issues with Linux
guests in VirtualBox and SDC-reader passthrough.
Thanks to Peter for the patch.
The commit introduces means to mark a task for destruction that is
removed on the next scheduling cycle. This fixes stack leakage from
dynamic kworker tasks.
Issue #4575.
* Move common SMP and NO_HZ_IDLE variables and functions into
generic lx_emul shadow implementations, and integrate them
into the common lx_emul import rules
* Enable SMP and NO_HZ_IDLE within virt_linux kernel configuration
* Adapt pc drivers and wireguard accordingly
* Use original Linux softirq implementation in wireguard
* Remove erroneous softirq shadow implementation

Enables symetric-multi-processor support in the Linux kernel configuration
used as base for the driver ports for PC. This is done to be compliant with
common usage of x86 drivers today.
Moreover, this commit uses the original kernel source for softirq/tasklet
implementation to get rid of the insufficient shadow implementation
in the lx_emul sources.
Ref genodelabs/genode#4562
Prepare shadow implementations in spinlocks, pagetable defines,
and irq_stack assembler macros to be able to enable SMP on x86/PC.

Use common implementation used by wifi and (not merged) audio driver.
Avoid usage of lib/delay.c since lpj and loop_for_jiffies are not calibrated
for the ported drivers as done on native Linux during boot and leads to wrong
delays for usb and intel_fb.
Issue #4540
Adhere to include/linux/rcutiny.h behaviour, which sets the max timeout
for rcu_needs_cpu. Without the commit, in the most cases the timeout value
is zero (or random since the pointer is on stack uninitialized), which leads
to programming very short timeouts again and again, making the system never
idle.
