This also means we stop recounting segments except for cloning

As is, iolatency recognizes done_bio and cleanup as ending paths. If a

clang warns about unusual code in floppy.c that looks like it
was intended to be a bit mask operation, checking for a specific
bit in the UDP->cmos variable (FLOPPY1_TYPE expands to '4' on
ARM):

drivers/block/floppy.c:3902:17: error: use of logical '&&' with constant operand [-Werror,-Wconstant-logical-operand]
        if (!UDP->cmos && FLOPPY1_TYPE)

drivers/block/floppy.c:3902:17: note: use '&' for a bitwise operation
        if (!UDP->cmos && FLOPPY1_TYPE)

The check here is redundant anyway, if FLOPPY1_TYPE is zero, then
assigning it to a zero UDP->cmos field does not change anything,
so removing the extra check here has no effect other than shutting
up the warning.

On x86, this will no longer read a hardware register, as the
FLOPPY1_TYPE macro is not expanded if UDP->cmos is already
zero, but the result is the same.

blkg alloc is performed as a separate step from the rest of blkg
creation so that GFP_KERNEL allocations can be used when creating
blkgs from configuration file writes because otherwise user actions
may fail due to failures of opportunistic GFP_NOWAIT allocations.

While making blkgs use percpu_ref, 7fcf2b03 ("blkcg: change blkg
reference counting to use percpu_ref") incorrectly added unconditional
opportunistic percpu_ref_init() to blkg_create() breaking this
guarantee.

This patch moves percpu_ref_init() to blkg_alloc() so makes it use
@gfp_mask that blkg_alloc() is called with.  Also, percpu_ref_exit()

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct bio_map_data {
	...
        struct iovec iov[];
};

instance = kmalloc(sizeof(sizeof(struct bio_map_data) + sizeof(struct iovec) *
                          count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kmalloc(struct_size(instance, iov, count), GFP_KERNEL);

Andy reported that raid10 array with SSD disks has poor
read performance. Compared with raid1, RAID-1 can be 3x
faster than RAID-10 sometimes [1].

The thing is that raid10 chooses the low distance disk
for read request, however, the approach doesn't work
well for SSD device since it doesn't have spindle like
HDD, we should just read from the SSD which has less
pending IO like commit 9dedf603 ("md/raid1: read
balance chooses idlest disk for SSD").

So this commit selects the idlest SSD disk for read if
array has none rotational disk, otherwise, read_balance
uses the previous distance priority algorithm. With the
change, the performance of raid10 gets increased largely
per Andy's test [2].

The 5.1 mount system rework changed the smackfsdef mount option to
smackfsdefault.  This fixes the regression by making smackfsdef treated
the same way as smackfsdefault.

Also fix the smack_param_specs[] to have "smack" prefixes on all the
names.  This isn't visible to a user unless they either:

 (a) Try to mount a filesystem that's converted to the internal mount API
     and that implements the ->parse_monolithic() context operation - and
     only then if they call security_fs_context_parse_param() rather than
     security_sb_eat_lsm_opts().

     There are no examples of this upstream yet, but nfs will probably want
     to do this for nfs2 or nfs3.

 (b) Use fsconfig() to configure the filesystem - in which case
     security_fs_context_parse_param() will be called.

This issue is that smack_sb_eat_lsm_opts() checks for the "smack" prefix
on the options, but smack_fs_context_parse_param() does not.

 - three fixes for Intel VT-d to fix a potential dead-lock, a formatting
   fix and a bit setting fix

 - one fix for the ARM-SMMU to make it work on some platforms with
   sub-optimal SMMU emulation

  iommu/arm-smmu: Avoid constant zero in TLBI writes
  iommu/vt-d: Set the right field for Page Walk Snoop
  iommu/vt-d: Fix lock inversion between iommu->lock and device_domain_lock

Pull sound fixes from Takashi Iwai:
 "It might feel like deja vu to receive a bulk of changes at rc5, and it
  happens again; we've got a collection of fixes for ASoC. Most of fixes
  are targeted for the newly merged SOF (Sound Open Firmware) stuff and
  the relevant fixes for Intel platforms.

  Other than that, there are a few regression fixes for the recent ASoC
  core changes and HD-audio quirk, as well as a couple of FireWire fixes
  and for other ASoC codecs"

* tag 'sound-5.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (54 commits)
