blit_x and blit_y are u32, so fbcon currently cannot support fonts
larger than 32x32.
The 32x32 case also needs shifting an unsigned int, to properly set bit
31, otherwise we get "UBSAN: shift-out-of-bounds in fbcon_set_font",
as reported on:

all vCPUs have been kicked, KVM only needs to guarantee that all vCPUs
will switch to the new filter before exiting to userspace. Protecting
the write to __reprogram_pmi is also unnecessary as a vCPU may process
a set bit before receiving the final KVM_REQ_PMU, but the per-vCPU writes
are guaranteed to occur after all vCPUs have switched to the new filter.

Intel SDM describes what steps are taken by the CPU to verify if a
memory segment can actually be used at a given privilege level. Loading
DS/ES/FS/GS involves checking segment's type as well as making sure that
neither selector's RPL nor caller's CPL are greater than segment's DPL.
Emulator implements Intel's pseudocode in __load_segment_descriptor(),
even quoting the pseudocode in the comments. Although the pseudocode is
correctly translated, the implementation is incorrect. This is most
likely due to SDM, at the time, being wrong.
Patch fixes emulator's logic and updates the pseudocode in the comment.
Below are historical notes.
Emulator code for handling segment descriptors appears to have been
introduced in March 2010 in commit 38ba30ba51a0 ("KVM: x86 emulator:
Emulate task switch in emulator.c"). Intel SDM Vol 2A: Instruction Set
Reference, A-M (Order Number: 253666-034US, _March 2010_) lists the
steps for loading segment registers in section related to MOV
instruction:
IF DS, ES, FS, or GS is loaded with non-NULL selector
THEN
IF segment selector index is outside descriptor table limits
or segment is not a data or readable code segment
or ((segment is a data or nonconforming code segment)
and (both RPL and CPL > DPL)) <---
THEN #GP(selector); FI;
This is precisely what __load_segment_descriptor() quotes and
implements. But there's a twist; a few SDM revisions later
(253667-044US), in August 2012, the snippet above becomes:
IF DS, ES, FS, or GS is loaded with non-NULL selector
THEN
IF segment selector index is outside descriptor table limits
or segment is not a data or readable code segment
or ((segment is a data or nonconforming code segment)
[note: missing or superfluous parenthesis?]
or ((RPL > DPL) and (CPL > DPL)) <---
THEN #GP(selector); FI;
Many SDMs later (253667-065US), in December 2017, pseudocode reaches
what seems to be its final form:
IF DS, ES, FS, or GS is loaded with non-NULL selector
THEN
IF segment selector index is outside descriptor table limits
OR segment is not a data or readable code segment
OR ((segment is a data or nonconforming code segment)
AND ((RPL > DPL) or (CPL > DPL))) <---
THEN #GP(selector); FI;
which also matches the behavior described in AMD's APM, which states that
a #GP occurs if:
The DS, ES, FS, or GS register was loaded and the segment pointed to
was a data or non-conforming code segment, but the RPL or CPL was
greater than the DPL.

We currently allocate the vgic maintenance interrupt by calling into
the low-level irqdomain code. Not only this is unnecessary, but this
is also pretty wrong: we end-up skipping a bunch of irqdesc state
setup
A simple "cat /proc/interrupt" shows how wrong we are, as the
interrupt appears as "Edge" instead of "Level".
Instead, just call the standard irq_create_fwspec_mapping(), which
is the right tool for the job. Duh.

The EL2 state is not initialised correctly when a CPU comes out of
CPU_{SUSPEND,OFF} as the finalise_el2 function is not being called.
Let's directly call finalise_el2_state from this path to solve the
issue.

Factor out the first half of the finalise_el2 function into a macro to
allow its reuse from the nVHE PSCI relay code. While at it, make the
register allocation parametric for the check_override macros as they are
now more widely exposed.
No functional changes intended.

good about getting fixes in quickly.
The other DT fixes are for the Nuvoton wpcm450 flash controller and
the i2c mux on an ASpeed board.

Pull s390 fixes from Heiko Carstens:
- With CONFIG_VMAP_STACK enabled it is not possible to load the s390
specific diag288_wdt watchdog module. The reason is that a pointer to
a string is passed to an inline assembly; this string however is
located on the stack, while the instruction within the inline
assembly expects a physicial address. Fix this by copying the string
to a kmalloc'ed buffer.
- The diag288_wdt watchdog module does not indicate that it accesses
memory from an inline assembly, which it does. Add "memory" to the
clobber list to prevent the compiler from optimizing code incorrectly
away.
- Pass size of the uncompressed kernel image to __decompress() call.
Otherwise the kernel image decompressor may corrupt/overwrite an
initrd. This was reported to happen on s390 after commit 2aa14b1ab2c4
("zstd: import usptream v1.5.2").

The code expect the PHY to be in power down which is only true after reset.
Allow changes of the SGMII parameters more than once.
Only power down when reconfiguring to avoid bouncing the link when there's
no reason to - based on code from Russell King.
There are cases when the SGMII_PHYA_PWD register contains 0x9 which
prevents SGMII from working. The SGMII still shows link but no traffic
can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was
taken from a good working state of the SGMII interface.
