  parisc: Replace PT_NLEVELS with CONFIG_PGTABLE_LEVELS
  parisc: Eliminate sg_virt_addr() and private scatterlist.h

The following warning is seen when compiling parisc images

The only reason to keep parisc's private asm/scatterlist.h was that it
had the macro sg_virt_addr().  Convert all callers to use something else
(sometimes just sg->offset was enough, others should use sg_virt()), and
we can just use the asm-generic scatterlist.h instead.

can't find it in my black heart to care too much about.  But this one
was just annoying me:

   drivers/media/v4l2-core/videobuf2-core.c:3256:26: warning: unused variable ‘fileio’ [-Wunused-variable]

because commit 0e661006 ("[media] vb2: fix 'UNBALANCED' warnings
when calling vb2_thread_stop()") removed all users of 'fileio' and
instead calls "__vb2_cleanup_fileio(q)" to clean up q->fileio.  But the

This reverts commit e2ac55b6.

Huang Ying reports that this causes a hang at boot with debugfs disabled.

It is true that the debugfs error checks are kind of confusing, and this
code certainly merits more cleanup and thinking about it, but there's
something wrong with the trivial "check not just for NULL, but for error
pointers too" patch.

Yes, with debugfs disabled, we will end up setting the o2hb_debug_dir
pointer variable to an error pointer (-ENODEV), and then continue as if
everything was fine.  But since debugfs is disabled, all the _users_ of
that pointer end up being compiled away, so even though the pointer can
not be dereferenced, that's still fine.

So it's confusing and somewhat questionable, but the "more correct"
error checks end up causing more trouble than they fix.

Yes, it should work, but it's a bad idea.  Not only did ARM64 not have
the 16-bit access code (there's a separate patch to add it), it's just
not a good atomic type.  Some architectures fundamentally don't do
atomic accesses in them (alpha), and it's not like it saves any space
here anyway because of structure packing issues.

We normally should aim for flags to be "unsigned int" or "unsigned
long".  And if space is at a premium, use a single byte (although that
causes problems on alpha again).  There might be very special cases
where a 16-byte entity is really wanted, but this is not one of them.

The test_data_1_le[] array is a const array of const char *.  To avoid
dropping any const information, we need to use "const char * const *",
not just "const char **".

I'm not sure why the different test arrays end up having different
const'ness, but let's make the pointer we use to traverse them as const
as possible, since we modify neither the array of pointers _or_ the
pointers we find in the array.

This prevents a race between chown() and execve(), where chowning a
setuid-user binary to root would momentarily make the binary setuid

Commit 8053871d ("smp: Fix smp_call_function_single_async()
locking") fixed the locking for the asynchronous smp-call case, but in
the process of moving the lock handling around, one of the error cases
ended up not unlocking the call data at all.

This went unnoticed on x86, because this is a "caller is buggy" case,
where the caller is trying to call a non-existent CPU.  But apparently
ARM does that (at least under qemu-arm).  Bindly doing cross-cpu calls
to random CPU's that aren't even online seems a bit fishy, but the error
handling was clearly not correct.

Simply add the missing "csd_unlock()" to the error path.
