firmware: arm_scmi: Avoid using extended string-buffers sizes if not necessary
Commit b260fccaebdc2 ("firmware: arm_scmi: Add SCMI v3.1 protocol extended
names support") moved all the name string buffers to use the extended buffer
size of 64 instead of the required 16 bytes. While that should be fine if
the firmware terminates the string before 16 bytes, there is possibility
of copying random data if the name is not NULL terminated by the firmware.
SCMI base protocol agent_name/vendor_id/sub_vendor_id are defined by the
specification as NULL-terminated ASCII strings up to 16-bytes in length.
The underlying buffers and message descriptors are currently bigger than
needed; resize them to fit only the strictly needed 16 bytes to avoid
any possible leaks when reading data from the firmware.
Change the size argument of strlcpy to use SCMI_SHORT_NAME_MAX_SIZE always
when dealing with short domain names, so as to limit the possibility that
an ill-formed non-NULL terminated short reply from the SCMI platform
firmware can leak stale content laying in the underlying transport shared
memory area.
While at that, convert all strings handling routines to use the preferred
strscpy.

All existing users of emulate_exception() have hardcoded vector numbers

all hardcoded), and future users are likely to follow suit, i.e. the
change to emulate_exception() is a glorified nop.

Note, bugging the VM doesn't completely prevent data corruption, e.g. the
current round of emulation will complete before the vCPU bails out to
userspace. But, the very act of killing the guest can also cause data
corruption, e.g. due to lack of file writeback before termination, so
taking on additional complexity to cleanly bail out of the emulator isn't
justified, the goal is purely to stem the bleeding and alert userspace

SIB encodings use 3 bits for GPRs, i.e. support 8 registers. x86-64 uses

KVM: x86: Harden _regs accesses to guard against buggy input
WARN and truncate the incoming GPR number/index when reading/writing GPRs
in the emulator to guard against KVM bugs, e.g. to avoid out-of-bounds
accesses to ctxt->_regs[] if KVM generates a bogus index. Truncate the
index instead of returning e.g. zero, as reg_write() returns a pointer
to the register, i.e. returning zero would result in a NULL pointer
dereference. KVM could also force the index to any arbitrary GPR, but
that's no better or worse, just different.
Open code the restriction to 16 registers; RIP is handled via _eip and
should never be accessed through reg_read() or reg_write(). See the
comments above the declarations of reg_read() and reg_write(), and the
behavior of writeback_registers(). The horrific open coded mess will be
cleaned up in a future commit.
There are no such bugs known to exist in the emulator, but determining
that KVM is bug-free is not at all simple and requires a deep dive into
the emulator. The code is so convoluted that GCC-12 with the recently
enable -Warray-bounds spits out a false-positive due to a GCC bug:

read value is capped at the specified size. I.e. 64-bit KVM is reading
memory beyond ctxt->regs_dirty, which is a u32 and thus 4 bytes, whereas
an unsigned long is 8 bytes. Functionally it's not an issue because
regs_dirty is in the middle of x86_emulate_ctxt, i.e. KVM is just reading
its own memory, but relying on that coincidence is gross and unsafe.

With fw_devlink=on by default, some of these devices might be blocked

devices and unblock the probing automatically, it might be too late by

This function is available to temporarily try and probe all devices that

The drivers can then decide which of the suppliers are optional vs

If a device successfully probes in this mode, we delete all fw_devlink
discovered dependencies of that device where the supplier hasn't yet

mei: me: set internal pg flag to off on hardware reset
Link reset flow is always performed in the runtime resumed state.
The internal PG state may be left as ON after the suspend
and will not be updated upon the resume if the D0i3 is not supported.
Ensure that the internal PG state is set to the right value on the flow
entrance in case the firmware does not support D0i3.

vme: move back to staging
The VME subsystem graduated from staging into a top-level subsystem in
2012, with commit db3b9e990e75 ("Staging: VME: move VME drivers out of
staging") stating:
The VME device drivers have not moved out yet due to some API
questions they are still working through, that should happen soon,
hopefully.
However, this never happened: maintenance of drivers/vme effectively
stopped in 2017, with all subsequent changes being treewide cleanups.
No hardware driver remains in staging, only the limited user-level
access, and I just removed one of the two bridge drivers and the only
remaining board.
drivers/staging/vme/devices/ was recently moved to
drivers/staging/vme_user/, but as the vme_user driver is the only one
remaining for this subsystem, it is easier to just move the remaining
three source files into this directory rather than keeping the original
hierarchy.

vme: remove ca91cx42 Universe-II support
This is one of four remaining drivers using the ancient
virt_to_bus() interface instead of the dma-mapping interface,
making it incompatible with most modern machines.
As nobody has cleaned this up, there is a high chance that this
driver has no actual users. The chip was introduced in 1997 and
only supports 32-bit legacy PCI. It was replaced by TSI148 in
2004, but that chip has since been discontinued, while a version
of the older Universe II remains in production after 25 years.
The vme_vmivme7805 board uses Universe-II, so this also gets
removed in the process, but PCI add-on cards based on TSI148
can still work in theory.
If there are users of the Universe-II driver after all, it is
of course possible to revert this patch and fix it to use the
dma-mapping interface like the tsi148 driver does.
