First, the btrfs_debug macros open-code (one possible definition of)
DYNAMIC_DEBUG_BRANCH, so they don't benefit from the CONFIG_JUMP_LABEL
optimization.

Second, a planned change of struct _ddebug (to reduce its size on 64 bit
machines) requires that all descriptors in a translation unit use
distinct identifiers.

Using the new _dynamic_func_call_no_desc helper macro from
dynamic_debug.h takes care of both of these.  No functional change.

For the upcoming 'define the _ddebug descriptor in assembly', we need
all the descriptors in a translation unit to have distinct names
(because asm does not understand C scope).  The easiest way to achieve
that is as usual with an extra level of macros, passing the identifier
to use to the innermost macro, generating it via __UNIQUE_ID or
something.

However, instead of repeating that exercise for dynamic_pr_debug,
dynamic_dev_dbg, dynamic_netdev_dbg and dynamic_hex_dump separately, we
can use the similarity between their bodies to implement them via a
common macro, _dynamic_func_call - though the hex_dump case requires a
slight variant, since print_hex_dump does not take the _ddebug
descriptor.  We'll also get to use that variant elsewhere (btrfs).

The only caller of ddebug_{add,remove}_module outside dynamic_debug.c is

be an interesting exercise to make that happen...).  I also fail to see
how these interfaces can be used by modules, in-tree or not.

Now that we store the passed-in string directly in ddebug_add_module, we
can use pointer equality instead of strcmp.  This is a little more
efficient, but more importantly, this also makes the code somewhat more
correct:

Currently, if one loads and then unloads a module whose name happens to
match the KBUILD_MODNAME of some built-in functionality (which need not
even be modular at all), all of their dynamic debug entries vanish along
with those of the actual module.  For example, loading and unloading a
core.ko hides all pr_debugs from drivers/base/core.c and other built-in
files called core.c (incidentally, there is an in-tree module whose name
is core, but I just tested this with an out-of-tree trivial one).

For built-in modules, we're already reusing the passed-in string via
kstrdup_const().  But for actual modules (i.e.  when we're called from
dynamic_debug_setup in module.c), the passed-in string (which points at
the name[] array inside struct module) is also guaranteed to live at
least as long as the struct ddebug_table, since free_module() calls
ddebug_remove_module().

Patch series "various dynamic_debug patches", v4.

This started as an experiment to see how hard it would be to change the
four pointers in struct _ddebug into relative offsets, a la
CONFIG_GENERIC_BUG_RELATIVE_POINTERS, thus saving 16 bytes per pr_debug
site (and thus exactly making up for the extra space used by the
introduction of jump labels in 9049fc74).  I stumbled on a few things
that are probably worth fixing regardless of whether that goal is deemed
worthwhile.

Back at v3 (in November), I redid the implementation on top of the fancy
new asm-macros stuff.  Luckily enough, v3 didn't get picked up, since
the asm-macros were backed out again.  I still want to do the
relative-pointers thing eventually, but we're close to the merge window
opening, so here's just most of the "incidental" patches, some of which
also serve as preparation for the relative pointers.

This patch (of 4):

dev_dbg_ratelimited tests the dynamic debug descriptor the old-fashioned
way, and doesn't utilize the static key/jump label implementation when
CONFIG_JUMP_LABEL is set.  Use the DYNAMIC_DEBUG_BRANCH which is defined
appropriately.

<linux/kernel.h> tends to be cluttered because we often put various sort
of unrelated stuff in it.  So, we have split out a sensible chunk of
code into a separate header from time to time.

This commit splits out the *_MAX and *_MIN defines.

The standard header <limits.h> contains various MAX, MIN constants
including numerial limits.  [1]

I think it makes sense to move in-kernel MAX, MIN constants into
include/linux/limits.h.

We already have include/uapi/linux/limits.h to contain some user-space
constants.  I changed its include guard to _UAPI_LINUX_LIMITS_H.  This
change has no impact to the user-space because
scripts/headers_install.sh rips off the '_UAPI' prefix from the include
guards of exported headers.

The commit log of 44f564a4 ("ipc: add definitions of USHORT_MAX and

and (unsigned short).

Let's use (short) and (unsigned short), which is more sensible, and more
consistent with the other MAX/MIN defines.

As you see in include/uapi/asm-generic/int-ll64.h, s16/u16 are
typedef'ed as signed/unsigned short.  So, this commit does not have a
functional change.

Remove the unneeded parentheses around ~0U while we are here.

BUILD_BUG_ON() is a little annoying, since it cannot be used outside
function scope.  So one cannot put assertions about the sizeof() a
struct next to the struct definition, but has to hide that in some more
or less arbitrary function.

Since gcc 4.6 (which is now also the required minimum), there is support
for the C11 _Static_assert in all C modes, including gnu89.  So add a
simple wrapper for that.

_Static_assert() requires a message argument, which is usually quite
redundant (and I believe that bug got fixed at least in newer C++
standards), but we can easily work around that with a little macro
magic, making it optional.

For example, adding

  static_assert(sizeof(struct printf_spec) == 8);

in vsprintf.c and modifying that struct to violate it, one gets

./include/linux/build_bug.h:78:41: error: static assertion failed: "sizeof(struct printf_spec) == 8"
 #define __static_assert(expr, msg, ...) _Static_assert(expr, "" msg "")

godbolt.org suggests that _Static_assert() has been support by clang
since at least 3.0.0.

Since commit a2e51445 ("kernel/hung_task.c: allow to set checking
interval separately from timeout") added hung_task_check_interval_secs,
setting a value different from hung_task_timeout_secs

  echo 0 > /proc/sys/kernel/hung_task_panic
  echo 120 > /proc/sys/kernel/hung_task_timeout_secs
  echo 5 > /proc/sys/kernel/hung_task_check_interval_secs

causes confusing output as if the task was blocked for
hung_task_timeout_secs seconds from the previous report.

  [  399.395930] INFO: task kswapd0:75 blocked for more than 120 seconds.
  [  405.027637] INFO: task kswapd0:75 blocked for more than 120 seconds.

Although we could update t->last_switch_time after sched_show_task(t) if
we want to report only every 120 seconds, reporting every 5 seconds
might not be very bad for monitoring after a problematic situation has
started.  Thus, let's use continuously blocked time instead of updating
previously reported time.

The single quotation marks around "const" were causing a documentation
markup warning with reST.  Instead of fixing that warning, just delete
that comment line and the gcc-3.3 hack of using "const" in the roundup()
macro since gcc-3.3 is no longer supported for kernel builds.

I did around 20 different $arch builds with no problems, but we'll just
have to see if this causes problems for anyone else out there.

Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE for
debugfs files.

Semantic patch information:
Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file()
imposes some significant overhead as compared to
DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().

Generated by: scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci

The _unsafe() part suggests that some of them "safeness
responsibilities" are now panic.c responsibilities.  The patch is OK
since panic's clear_warn_once_fops struct file_operations is safe
against removal, so we don't have to use otherwise necessary
debugfs_file_get()/debugfs_file_put().

The pm8xxx_get_channel() implementation is unclear, and causes gcc to
suddenly generate odd warnings.  The trigger for the warning (at least
for me) was the entirely unrelated commit 79a4e91d ("device.h: Add
__cold to dev_<level> logging functions"), which apparently changes gcc
code generation in the caller function enough to cause this:

  drivers/iio/adc/qcom-pm8xxx-xoadc.c: In function ‘pm8xxx_xoadc_probe’:
  drivers/iio/adc/qcom-pm8xxx-xoadc.c:633:8: warning: ‘ch’ may be used uninitialized in this function [-Wmaybe-uninitialized]
    ret = pm8xxx_read_channel_rsv(adc, ch, AMUX_RSV4,
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
             &read_nomux_rsv4, true);
             ~~~~~~~~~~~~~~~~~~~~~~~
  drivers/iio/adc/qcom-pm8xxx-xoadc.c:426:27: note: ‘ch’ was declared here
    struct pm8xxx_chan_info *ch;
                             ^~

because gcc for some reason then isn't able to see that the termination
condition for the "for( )" loop in that function is also the condition
for returning NULL.

So it's not _actually_ uninitialized, but the function is admittedly
just unnecessarily oddly written.

Simplify and clarify the function, making gcc also see that it always
returns a valid initialized value.
