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

Ref genodelabs/genode#4562
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.
Issue #4540
Querying the RFKILL state led to execution of the Lx_kit::scheduler by
the pthread running the wpa_supplicant. As this may not happen the
RFKILL state is now solely managed by the driver and only the cached
state is read by the supplicant.
Fixes#4537.
As accommodating the session component object is already taken care of
be the root component implementation, remove the remaining redundant
checks.
Fixes#4521.
Instead of allocating the stack via 'kmalloc' point it to the actual
stack used by the task. This addresses issues with the USB
host-controller driver where sometimes hub port enumeration is not
working.
Fixes#4522.
We locally disable 'address-of-packed-member' warnings because GCC complained
about possible alignment issues when returning a reference to a packed member
as naturally aligned pointer (for some reason only on arm_v8a). We know that
the member is aligned to NETDEV_ALIGN via __attribute__ and that the warning
is therefor unnecessary.
Ref #4519
We have to correct the CC_OPT_* variable for these files and used to do so via
phony pre-requisite for the corresponding object files because the correction
had to take place after the variable initialization in
import-lx_emul_common.inc and before the creation of the object files. However,
this caused the objects to always rebuild.
This commit fixes this issue by using Make's feature of target-specific
variables instead. The drawback of this solution is that we can no longer
override CC_OPT_* with a modification of its original value but instead have to
override with a completely new value. This is because otherwise, Make would
either complain about recursive assignment or produce an empty value.

The strict conversion warnings were disabled during development when the
contrib code was still compiled with the wireguard lib. Now this isn't
necessary anymore as the contrib code is in the wireguard_lx_inc_dirs lib.
