This controller's input and output logic is similar to previous
generations of SoCs. Additionally, it's capable of interrupt masking,
and could be configured to detect levels and edges, and is supplied with
a distinct reset signal.
The interrupt functionality is implemented through an irqchip, whose
operations are written with previous generation SoCs in mind and could
be reused. Since all Loongson SoCs with similar interrupt capability
(LS2K1500, LS2K2000) support byte-control mode, these operations are for
byte-control mode only for simplicity.

Loongson-2K0300 ships a GPIO controller whose input/output control logic
is similar to previous generation of SoCs. Additionally, it acts as an
interrupt-controller supporting both level and edge interrupts and has a
distinct reset signal.
Describe its compatible in devicetree. We enlarge the maximum value of
ngpios to 128, since the controller technically supports at most 128
pins, although only 106 are routed out of the package. Properties for
interrupt-controllers and resets are introduced and limited as LS2K0300
only.

The kexec_buf structure was previously declared without initialization.
commit bf454ec31a ("kexec_file: allow to place kexec_buf randomly")
added a field that is always read but not consistently populated by all
architectures. This un-initialized field will contain garbage.
This is also triggering a UBSAN warning when the uninitialized data was
accessed:
------------[ cut here ]------------
UBSAN: invalid-load in ./include/linux/kexec.h:210:10
load of value 252 is not a valid value for type '_Bool'
Zero-initializing kexec_buf at declaration ensures all fields are
cleanly set, preventing future instances of uninitialized memory being
used.

The type of the value to write should be determined by the size of the
destination, not by the value itself, which may be a constant. This
aligns the behavior with x86_64, where __typeof__(*(__gu_ptr)) is used
to infer the correct type.
This fixes an issue in put_cmsg, which was only writing 4 out of 8
bytes to the cmsg_len field, causing the glibc tst-socket-timestamp test
to fail.

would be unremarkable by itself, the whole series has had a good
