virtio_gpu: use an X8R8G8B8 resource on big-endian guests
The virtio-gpu resource formats are defined by byte order in memory,
while vt(4) and the X server (through vt_fb and the fb mmap) write
native 32-bit 0x00RRGGBB pixels into the shadow framebuffer. On a
big-endian guest such as powerpc64 those pixels land in memory as
00 RR GG BB, which the host interprets under B8G8R8X8 with red and
blue swapped and the padding byte taken as blue: white renders yellow
and blue renders black.
Request X8R8G8B8 on big-endian guests instead, which is also what the
Linux driver does (DRM_FORMAT_HOST_XRGB8888). Reproduced with a colour
test pattern on a powerpc64 QEMU pseries guest using the identically
coded out-of-tree fork of this driver (graphics/virtio-gpu-qemu-kmod);
little-endian guests are unchanged.

ipmi(4): improve debugging for ioctl(IPMICTL_SEND_COMMAND)
Add a knob to debug ioctl(IPMICTL_SEND_COMMAND). Log the IPMI NetFn and
Cmd fields, followed by a hexdump of the request data. Upon completion,
log the hexdump of the response data.

loader.efi: devinit() just after parsing args instead
c4640126f1160 ("loader.efi: Apply command-line DHCP overrides earlier")
was really good, but moving it just one statement earlier is even
better. polarian on Libera describes a GELI setup on a system that
doesn't advertise a serial console via ConOut. They don't have serial
input at the point that they would get prompted for the GELI passphrase,
but if we parse args just before devinit() then he can override the
console with `efibootmgr -e`. This gives UEFI one advantage over BIOS
loader, as /boot.config isn't available to provide that kind of override
if your impediment is GELI.
We also considered reading loader.env earlier, but we have a chicken/egg
problem in that we must have probed for the ESP to be able to open() it.
We would instead need a devinit_early() and devinit_late() scheme that
allows GELI probing to be deferred until the later pass, after reading
loader.env to pick up the console override. That's an idea I'd still
like to discuss because it's more robust than hoping that firmware won't
wipe out our efibootmgr(8) entries.

LinuxKPI: firmware: remove `enoentok` logic in `*firmware_request(..)`
Prior to this change, in the event that a firmware module could not be
loaded, the linux_firmware driver would return a partially initialized
structure with uninitialized/zeroed out values for certain fields. Linux
does not do this, however, so some drivers that use
`request_firmware_nowait` expecting Linux behavior, like `if_bcrmfmac`,
would crash trying to dereference a NULL pointer.
This doesn't address the load/unload situation completely as the driver
remains loaded after the "firmware crashes", but it makes a completely
unusable situation (a kernel panic) into a slightly more usable situation
(driver does not unload).
As a sidenote: the raw free(9) call was replaced with a call to
`linuxkpi_release_firmware` because the latter call [better] ensures
that all resources allocated earlier on in the function are cleaned up.

Merge commit c52392a6f464 from llvm-project (by ShengYi Hung):
[Clang][ExprConst] Drop PRValue for nothrow new (#226753)
A user defined operator new can accept prvalue for nothrow. However, it
should not be a ConstExpr. Early returns by
isUsableAsGlobalAllocationFunctionInConstantEvaluation instead of doing
LValue evaluation.
Also, move CheckPlacement new logic into new OpCode. This decouples
checking from Interp.cpp to Compiler.cpp.
This fixes "Assertion failed: (E->isGLValue() ||
E->getType()->isFunctionType() || E->getType()->isVoidType() ||
isa<ObjCSelectorExpr>(E->IgnoreParens())), function EvaluateLValue" when
building the databases/mariadb123-server port.
