The recent change to use pud_valid() as part of the implementation of
pud_user_accessible_page() fails to build when PGTABLE_LEVELS <= 2
because pud_valid() is not defined in that case.
Fix this by defining pud_valid() to false for this case. This means that
pud_user_accessible_page() will correctly always return false for this
config.

Calling mac_reset() on a Mac IIci does reset the system, but what
follows is a POST failure that requires a manual reset to resolve.
Avoid that by using the 68030 asm implementation instead of the C
implementation.
Apparently the SE/30 has a similar problem as it has used the asm
implementation since before git. This patch extends that solution to
other systems with a similar ROM.
After this patch, the only systems still using the C implementation are
68040 systems where adb_type is either MAC_ADB_IOP or MAC_ADB_II. This
implies a 1 MiB Quadra ROM.
This now includes the Quadra 900/950, which previously fell through to
the "should never get here" catch-all.

Context switching does take care to retain the correct lock owner across
the switch from 'prev' to 'next' tasks. This does rely on interrupts
remaining disabled for the entire duration of the switch.
This condition is guaranteed for normal process creation and context
switching between already running processes, because both 'prev' and
'next' already have interrupts disabled in their saved copies of the
status register.
The situation is different for newly created kernel threads. The status
register is set to PS_S in copy_thread(), which does leave the IPL at 0.
Upon restoring the 'next' thread's status register in switch_to() aka
resume(), interrupts then become enabled prematurely. resume() then
returns via ret_from_kernel_thread() and schedule_tail() where run queue
lock is released (see finish_task_switch() and finish_lock_switch()).
A timer interrupt calling scheduler_tick() before the lock is released
in finish_task_switch() will find the lock already taken, with the
current task as lock owner. This causes a spinlock recursion warning as
reported by Guenter Roeck.
As far as I can ascertain, this race has been opened in commit
533e6903bea0 ("m68k: split ret_from_fork(), simplify kernel_thread()")
but I haven't done a detailed study of kernel history so it may well
predate that commit.
Interrupts cannot be disabled in the saved status register copy for
kernel threads (init will complain about interrupts disabled when
finally starting user space). Disable interrupts temporarily when
switching the tasks' register sets in resume().
Note that a simple oriw 0x700,%sr after restoring sr is not enough here
- this leaves enough of a race for the 'spinlock recursion' warning to
still be observed.
Tested on ARAnyM and qemu (Quadra 800 emulation).

A few more Qualcomm Arm64 DeviceTree updates for v6.10
This corrects the obviously broken compatible of the USB VBUS regulator

It clears the odd-looking default address on QCS404 EVB, with the
expectation that a proper address is provides by other means.
The newly added SM8650 GPU node is corrected with a missing memory
region.

RISC-V SoC Kconfig Updates for v6.10
A few different bits of SoC-related Kconfig work. The first part of
this is shared with the DT updates - the modification of all SOC_CANAAN
users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away
from the k230 that is able to be used in a "common" kernel.
The other thing here is the removal of most of the SOC_VENDOR options,
with their ARCH_VENDOR equivalents that've been waiting in the wings for
1 year+ now made visible. Due a lapse on my part when originally adding
the ARCH_VENDOR stuff, the Microchip transition isn't complete - the
_POLARFIRE was a mistake to keep as there's gonna be non-PolarFire
RISC-V stuff from Microchip soonTM.

All EV4 machines are already gone, and the remaining EV5 based machines
all support the slightly more modern EV56 generation as well.
Debian only supports EV56 and later.
Drop both of these and build kernels optimized for EV56 and higher
when the "generic" options is selected, tuning for an out-of-order
EV6 pipeline, same as Debian userspace.
Since this was the only supported architecture without 8-bit and
16-bit stores, common kernel code no longer has to worry about
aligning struct members, and existing workarounds from the block
and tty layers can be removed.
The alpha memory management code no longer needs an abstraction
for the differences between EV4 and EV5+.

The ethernet-switch node does not have children with unit addresses, so
address/size-cells are not really correct, as reported by dtc W=1
warning:

This probably also fixes dtbs_check warning, but I could not find it, so
not sure about that.

thus we have one long compatible consisting of two compatible strings
leading to dtbs_check warnings:

APECS is the DECchip 21071x chipset for the EV4 and EV45 generation, while
LCA is the integrated I/O support on the corresponding low-cost alpha
machines of that generation.
All of these CPUs lack the BWX extension for byte and word access, so
drop the chipset support and all associated machines.

The sable family (Alphaserver 2000 and 2100) comes in variants for
EV4, EV45, EV5 and EV56. Drop support for the earlier ones that
lack support for the BWX extension but keep the later 'gamma'
variant around since that works with EV56 CPUs.

We want io.h primitives (readb(), etc.) to be extern inline.
However, that requires the backing out-of-line implementation
somewhere, preferably kept in sync with the inline ones.
The way it's done is __EXTERN_INLINE macro that defaults to
extern inline, but can be overridden in compilation unit where
the out-of-line instance will be.
That works, but it's brittle - we *must* make sure that asm/io.h
is the very first include in such compilation units. There'd
been a bunch of bugs of that sort in the past.
Another issue is the choice of overriding definition for
__EXTERN_INLINE; it must be either 'inline' or empty. Either
will do for compilation purposes - inline void foo(...) {...}
(without extern or static) is going to generate out-of-line
instance. The difference is that 'definition without a
prototype' heuristics trigger on
void foo(void)
{
...
}
but not on
inline void foo(void)
{
...
}
Most of the overrides go for 'inline'; in two cases (sys_jensen
and core_t2) __EXTERN_INLINE is defined as empty. Without
-Wmissing-prototypes it didn't matter, but now that we have
that thing always on...

definitions of avanti_mv and noname_mv (and associated ALIAS_MV)
are conditional upon the wrong thing - it should be
CONFIG_ALPHA_{AVANTI,NONAME}_CH, not CONFIG_ALPHA_{AVANTI,NONAME}.
The former is a system type; the latter is for the bits shared
by AVANTI with XL and NONAME with ALPHA_BOOK1 resp.
We want all those machine vectors defined (but not aliased - see
ALIAS_MV() definition for details) for GENERIC build; for
system-specfic builds we want only one mv, so avanti_mv should *not*
be there for XL; it certainly should not be have alpha_mv aliased to
it on such config - xl_mv will be there and alpha_mv can't be aliased
to both of those.
The same goes for Noname vs. Alphabook1.

On alpha str{n,}{cpy,cat}() implementations are playing
fun games with shared chunks of code. The problem is, they are
using direct branches and need to be next to each other.
Currently it's done by building them in separate object
files, then using ld -r to link those together. Unfortunately,
genksyms machinery has no idea what to do with that - we have
generated in arch/alpha/lib/.strcat.S.cmd, but there's nothing
to propagate that into .stycpy.S.cmd, so modpost doesn't find
anything for those symbols, resulting in
WARNING: modpost: EXPORT symbol "strcpy" [vmlinux] version generation failed, symbol will not be versioned.
Is "strcpy" prototyped in <asm/asm-prototypes.h>?
WARNING: modpost: EXPORT symbol "strcat" [vmlinux] version generation failed, symbol will not be versioned.
Is "strcat" prototyped in <asm/asm-prototypes.h>?
WARNING: modpost: EXPORT symbol "strncpy" [vmlinux] version generation failed, symbol will not be versioned.

WARNING: modpost: EXPORT symbol "strncat" [vmlinux] version generation failed, symbol will not be versioned.
Is "strncat" prototyped in <asm/asm-prototypes.h>?
spew on modversion-enabled builds (all 4 functions in question
are in fact prototyped in asm-prototypes.h)
Fixing doesn't require messing with kbuild, thankfully -
just build one object (i.e. have sty{n,}cpy.S with includes of relevant
*.S instead of playing with ld -r) and that's it.

Take scr_memmove() out of line, make both it and scr_memcpyw()
conditional upon VGA_CONSOLE or MDA_CONSOLE (if neither is
selected, we are certain to be working with the kernel-allocated
buffer rather than VRAM and defaults will work just fine).
That allows to clean vt_buffer.h, but that's a separate story
