commit b344d6a83d01 ("parisc: add support for cmpxchg on u8 pointers")
can generate a sparse warningi ("cast truncates bits from constant
value"), which has been reported several times [1] [2] [3].
The original code worked as expected, but anyway, let silence such
sparse warning
Greeting,
FYI, we noticed the following commit (built with gcc-9):

Use the map-requests pool as there is no point in assigning a

pci_resource_start() is not a good indicator to determine if a PCI

This is seen when trying to instantiate the driver in qemu for riscv32

Most MT7621 SoCs have 2 cores, which is detected and supported properly
by CPS.
Unfortunately, MT7621 SoC has a less common S variant with only one core.
On MT7621S, GCR_CONFIG still reports 2 cores, which leads to hangs when
starting SMP. CPULAUNCH registers can be used in that case to detect the

ITMT relies on asymmetric packing of tasks to ensure CPUs are populated in
priority order. When balancing load, the scheduler compares scheduling
groups in pairs, and compares only the priority of the CPUs of highest
priority in the group. This may result on CPUs with medium priority being

Introduce arch_sched_asym_prefer_early() so that architectures with SMT

When using asymmetric packing, high priority idle CPUs pull tasks from
