This avoids random crashes on my Powerbook when using the mouse or keyboard.
The same was needed for the Powerbook 5xx/Duos (compile tested only).
XXX pullup-10, pullup-9, pullup-8.
Fixes the build without MPBIOS or ACPI. Modified patch from Paolo Pisati in
current-users@.
While here:
Remove obsolete <arch/x86/pci/msipic.h> include with its guard.
Add comments for multiple endifs for better readability.
(Path from Paolo Pisati in current_users@)
While here:
Simplify mp_cpu_start() ifdefs. MULTIPROCESSOR and HYPERV code falls under
NLAPIC > 0, thus just combine all blocks under this guard.
Rearrange opt_acpi.h include alphabetically.
Let's just see how this works out in practice. Might need to reduce
the overhead of each GHES on machines with thousands of them, but
we'll see.

On NetBSD, libdrm uses this to discover what kind of bus the device
is on, without which it refuses to expose the render node at all,
rendering it useless. With this change, libdrm is able to use render
nodes on NetBSD.
Since this is just reading out information about the bus type and
bus/dev/func numbers, I don't think it's problematic to expose to
render nodes.
This requires tweaking the access path to the master.

Fix edge default values, factor out percentage calculation for more consistent
values. Use device_printf/DPRINTF to show errors instead of aprint variants.
Print raw input for debugging.
Correct capability parsing. Old devices were probed with nonexistent
commands and then used undefined boundary values that made them unusuable.
Fixes PR 57874.
the u_long mdpg_attrs aren't dropped giving atomic_cas_ulong no
chance of completing if any of the top bits is set.
Update pmap_page_set_attributes for consistency.
An ATF test run completed for me with this fix.
port-riscv/58006: ATF tests no longer complete on riscv-riscv64
It doesn't make a difference here, because tap_detach never fails,
but let's make it more obvious at the call site that failure is
forbidden here.
No functional change intended.
PR kern/58166
Leave a little ACPI-related functionality disabled for now, like
getting EDID out of ACPI -- needs a bit more work to make this work,
and I don't have hardware to work on that.
Should help with failures of the forms:
- unable to locate a BIOS ROM
- bios: unable to locate usable image
on various machines.

1. sendsig_siginfo() previously assumed that user SP was always aligned to
16 bytes and could call signal handlers with SP misaligned. This is a
wrong assumption because aarch64 demands that SP is aligned *only while*
it's being used to access memory. Now it properly aligns it before
pusing anything on the stack.
2. cpu_mcontext_validate() used to check if _REG_SP was aligned and
considered the ucontext invalid otherwise. This meant if a signal was
sent to a process whose SP was misaligned, the signal handler would fail
to return because the ucontext passed from the kernel was an invalid
one. Now setcontext(2) doesn't complain about misaligned SP.
Don't unconditionally set XN in pmap_clearbit - only set it if a mapping
exists VM_PROT_EXEC is being cleared.
I've simplified the #ifdefs in the patch from the PR.
