Extending the Arm SMMU driver to allow for modular builds changed
KBUILD_MODNAME to be "arm_smmu_mod" so that a single module could be
built from the multiple existing object files without the need to rename
any source files.

This inadvertently changed the name of the driver parameters, which may
lead to runtime issues if bootloaders are relying on the old names for
correctness (e.g. "arm-smmu.disable_bypass=0").

Although MODULE_PARAM_PREFIX can be overridden to restore the old naming
for builtin parameters, only the new name is matched by modprobe and so
loading the driver as a module would cause parameters specified on the
kernel command line to be ignored. Instead, rename "arm_smmu_mod" to
"arm_smmu". Whilst it's a bit of a bodge, this allows us to create a
single module without renaming any files and makes use of the fact that
underscores and hyphens can be used interchangeably in parameter names.

Currently, the implementation of qcom_iommu_domain_free() is guaranteed
to do one of two things: WARN() and leak everything, or dereference NULL
and crash. That alone is terrible, but in fact the whole idea of trying
to track the liveness of a domain via the qcom_domain->iommu pointer as
a sanity check is full of fundamentally flawed assumptions. Make things
robust and actually functional by not trying to be quite so clever.

Andrei Vagin reported that commit 0ddad21d ("pipe: use exclusive
waits when reading or writing") broke one of the CRIU tests.  He even
has a trivial reproducer:

    #include <unistd.h>
    #include <sys/types.h>
    #include <sys/wait.h>

    int main()
    {
            int p[2];
            pid_t p1, p2;
            int status;

            if (pipe(p) == -1)
                    return 1;

            p1 = fork();
            if (p1 == 0) {
                    close(p[1]);
                    read(p[0], &status, sizeof(status));
                    return 0;
            }
            p2 = fork();
            if (p2 == 0) {
                    close(p[1]);
                    read(p[0], &status, sizeof(status));
                    return 0;
            }
            sleep(1);
            close(p[1]);
            wait(&status);
            wait(&status);

            return 0;
    }

and the problem - once he points it out - is obvious.  We use these nice
exclusive waits, but when the last writer goes away, it then needs to
wake up _every_ reader (and conversely, the last reader disappearing
needs to wake every writer, of course).

In fact, when going through this, we had several small oddities around
how to wake things.  We did in fact wake every reader when we changed
the size of the pipe buffers.  But that's entirely pointless, since that
just acts as a possible source of new space - no new data to read.

And when we change the size of the buffer, we don't need to wake all
writers even when we add space - that case acts just as if somebody made
space by reading, and any writer that finds itself not filling it up
entirely will wake the next one.

On the other hand, on the exit path, we tried to limit the wakeups with
the proper poll keys etc, which is entirely pointless, because at that
point we obviously need to wake up everybody.  So don't do that: just
wake up everybody - but only do that if the counts changed to zero.

So fix those non-IO wakeups to be more proper: space change doesn't add
any new data, but it might make room for writers, so it wakes up a
writer.  And the actual changes to reader/writer counts should wake up
everybody, since everybody is affected (ie readers will all see EOF if
the writers have gone away, and writers will all get EPIPE if all
readers have gone away).

If CONFIG_LOAD_UEFI_KEYS is enabled, the kernel attempts to load the certs
from the db, dbx and MokListRT EFI variables into the appropriate keyrings.

But it just assumes that the variables will be present and prints an error
if the certs can't be loaded, even when is possible that the variables may
not exist. For example the MokListRT variable will only be present if shim
is used.

So only print an error message about failing to get the certs list from an
EFI variable if this is found. Otherwise these printed errors just pollute
the kernel log ring buffer with confusing messages like the following:

ASoC: Fixes for v5.6

A few fixes sent in since the merge window, none of them with global
impact but all important for the users they affect.

Some code in HD-audio driver calls snprintf() in a loop and still
expects that the return value were actually written size, while
snprintf() returns the expected would-be length instead.  When the
given buffer limit were small, this leads to a buffer overflow.

Use scnprintf() for addressing those issues.  It returns the actually
written size unlike snprintf().

The only time we actually leave the path spinning is if we're truncating
a small amount and don't actually free an extent, which is not a common
occurrence.  We have to set the path blocking in order to add the
delayed ref anyway, so the first extent we find we set the path to
blocking and stay blocking for the duration of the operation.  With the
upcoming file extent map stuff there will be another case that we have
to have the path blocking, so just swap to blocking always.

Note: this patch also fixes a warning after 28553fa9 ("Btrfs: fix
race between shrinking truncate and fiemap") got merged that inserts
extent locks around truncation so the path must not leave spinning locks
after btrfs_search_slot.

Pull EDAC fixes from Borislav Petkov:
 "Two fixes for use-after-free and memory leaking in the EDAC core, by
  Robert Richter.

  Debug options like DEBUG_TEST_DRIVER_REMOVE, KASAN and DEBUG_KMEMLEAK
  unearthed issues with the lifespan of memory allocated by the EDAC
  memory controller descriptor due to misdesigned memory freeing, done
  partially by the EDAC core *and* the driver core, which is problematic
  to say the least.

  These two are minimal fixes to take care of stable - a proper rework
  is following which cleans up that mess properly"
