Instead of calling RUN_P2 at the very beginning of both cpu-specific

them.  Drop RUN_P1 at the end as we are getting back to P1 anyway

The evaluation flags passed to the nested variables consist of 3 flags.
Therefore, (eflags & VARE_UNDEFERR) | (eflags & VARE_WANTRES) is

Gather the conditions to return from the VCPU loops in nvmm_return_needed(),
and use it in nvmm_do_vcpu_run() as well. This fixes two undesired behaviors:

- When a VM initializes, the many nested page faults that need processing
  could cause the calling thread to occupy the CPU too much if we're unlucky
  and are only getting repeated nested page faults thousands of times in a
  row.

- When the emulator calls nvmm_vcpu_run() and immediately sends a signal to
  stop the VCPU, it's better to check signals earlier and leave right away,
  rather than doing a round of VCPU run that could increase the time spent
  by the emulator waiting for the return.

make(1): replace one instance of strncpy with snprintf

GCC 9 incorrectly claims that the string might not be null-terminated.
Since objdir is a global variable, it is initialized to zero, and the +1
in the size guarantees that this byte is always 0.

Still, using strncpy to initialize a string is a waste of memory access,
since it is enough if only the actual data is copied, without zeroing
out all the remaining bytes.

(martin)

(maxv)

Note PAN.

(maxv)

Add support for Privileged Access Never (ARMv8.1-PAN).

PAN provides the same functionality as SMAP on x86: it forbids kernel
access to userland pages when PSTATE.PAN=1, and allows such accesses when
PSTATE.PAN=0.

We clear SCTLR_SPAN, to guarantee that PAN=1 each time the kernel is
entered. We catch PAN faults and panic right away without further
processing. In copyin, copyout, etc, we temporarily authorize access to
userland pages.

PAN is a very useful exploit mitigation. Reviewed by ryo@, thanks. Tested
on Qemu. Enabled by default.

make(1): switch Buffer size from int to size_t

This change helps to make the various integer types compatible and is a
preparational step for setting WARNS=6 in the Makefile.

The documentation of buf.c has been cleaned up and condensed since it
was mostly redundant, and some statements were even slightly wrong.

All code changes are covered by the existing unit tests, except for the
few lines in for.c around for_var_len.  These changes have been reviewed
thoroughly and manually, like all the others in this commit.

Those buffer functions that deal with sizes have been renamed by
appending a Z, to make sure that no function call was accidentally
forgotten.  They will be renamed back in a follow-up commit.

As usual, the scope of a few affected variables has been reduced, and
some variables had to be split since they had been incorrectly merged
before.

The order of the arguments to Buf_AddBytes has changed from (mem_len,
mem) to (mem, mem_len), in order to make it consistent with the
functions from the C standard library, such as snprintf.

PR bin/55526

Fix a bug that has existed since the "command" command was added in
2003.  "command foo" would cause the definition of a function "foo"
to be lost (not freed, simply discarded) if "foo" is (in addition to
being a function) a filesystem command.  The case where "foo" is
a builtin was handled.

For now, when a function exists with the same name as a filesystem
command, the latter can never appear in the command hash table, and
when used (which can only be via "command foo", just "foo" finds
the function) will always result in a full PATH search.

can define kthread_fpu_enter/exit_md to actually enable/disable the
FPU.  (These are almost pcu_load/discard on systems that use pcu(9),
except they apply to all PCUs.)

Discussed on tech-kern:
https://mail-index.netbsd.org/tech-kern/2020/06/20/msg026524.html

The proposed kthread flag KTHREAD_FPU is not included because I
couldn't find any particular need for it that would not be covered by
just calling kthread_fpu_enter/exit in the kthread function.

Use "empty" for rmlvo model and layout to avoid lingering default settings.

Now all modifier keys (CTRL, SHIFT, and NumLock) work as expected.

It seems XkbApplyMappingChange() doesn't update some XKB modifier
settings even if new modmap data is specified.

Minor formatting tweaks.

Swtich from -ohang to -tag lists.

-ohang lists are hard to read b/c long config directives are almost
impossible to tell from the following text.  Occasional multi-paragraph
descriptions were quite confusing too.

Missed formatting fixes for "no makeoptions".

(uwe)

The tale of two makeoptions.

There are two forms that were both documented in the selections
section, but the form with the condition (and only that form) can be
used only in the descriptions section.  Move it to the appropriate .Ss
and add prominent notice to both.

Formatting improvements.

make(1): automate adding or removing test files

(rillig)

Minor tweak to list formatting.

Where necessary, use .Bl -ohang -compact and explicit .Pp to be able
to group multiple config directives (separate .It) by omitting .Pp
between them.

While here, add a .|" comment before .It to make them more visible
when editing.

make(1): document another instance of undefined behavior

The UNCONST macro is really terrible.

This segmentation fault can be forced by setting _PATH_DEFSYSMK in
pathnames.h to "./sys*.mk" or any other string that has a slash and a
wildcard to the right of the slash.

- don't overwrite existing error.
- return the error not 0 if failing.

Add -dL for LINT

When parsing variable assignments other than := and if
value contains '$' attempt Var_Subst the same as for :=,
if the value does not parse correctly, we get a fatal error
including file an line number.

This can greatly help with finding the cause of problems.
