  dma-mapping: fix tracing dma_alloc/free with vmalloc'd memory

Not all virtual addresses have physical addresses, such as if they were
vmalloc'd. Just trace the virtual address instead of trying to trace a
physical address. This aligns with the API, and is good enough to
associate dma_alloc with dma_free.

The "addr" and "is_shmem" arguments have different order in TP_PROTO and
TP_ARGS.  This resulted in the incorrect trace result:

text-hugepage-644429 [276] 392092.878683: mm_khugepaged_collapse_file:
mm=0xffff20025d52c440, hpage_pfn=0x200678c00, index=512, addr=1, is_shmem=0,
filename=text-hugepage, nr=512, result=failed

The value of "addr" is wrong because it was treated as bool value, the
type of is_shmem.

Fix the order in TP_PROTO to keep "addr" is before "is_shmem" since the
original patch review suggested this order to achieve best packing.

And use "lx" for "addr" instead of "ld" in TP_printk because address is
typically shown in hex.

After the fix, the trace result looks correct:

text-hugepage-7291  [004]   128.627251: mm_khugepaged_collapse_file:
mm=0xffff0001328f9500, hpage_pfn=0x20016ea00, index=512, addr=0x400000,
is_shmem=0, filename=text-hugepage, nr=512, result=failed

Pull btrfs fixes from David Sterba:

 - in incremental send, fix invalid clone operation for file that got
   its size decreased

 - fix __counted_by() annotation of send path cache entries, we do not
   store the terminating NUL

 - fix a longstanding bug in relocation (and quite hard to hit by
   chance), drop back reference cache that can get out of sync after
   transaction commit

 - wait for fixup worker kthread before finishing umount

 - add missing raid-stripe-tree extent for NOCOW files, zoned mode
   cannot have NOCOW files but RST is meant to be a standalone feature

 - handle transaction start error during relocation, avoid potential
   NULL pointer dereference of relocation control structure (reported by
   syzbot)

 - disable module-wide rate limiting of debug level messages

 - minor fix to tracepoint definition (reported by checkpatch.pl)

  btrfs: also add stripe entries for NOCOW writes
  btrfs: send: fix buffer overflow detection when copying path to cache entry

While running checkpatch.pl against a patch that modifies the
btrfs_qgroup_extent event class, it complained about using a comma instead
of a semicolon:

  $ ./scripts/checkpatch.pl qgroups/0003-btrfs-qgroups-remove-bytenr-field-from-struct-btrfs_.patch
  WARNING: Possible comma where semicolon could be used
  #215: FILE: include/trace/events/btrfs.h:1720:
  +		__entry->bytenr		= bytenr,
		__entry->num_bytes	= rec->num_bytes;

  total: 0 errors, 1 warnings, 184 lines checked

So replace the comma with a semicolon to silence checkpatch and possibly
other tools. It also makes the code consistent with the rest.

  dma-mapping: fix DMA API tracing for chained scatterlists

scatterlist allocations can be chained, and thus all iterations need to
use the chain-aware iterators.  Switch the newly added tracing to use the
proper iterators so that they work with chained scatterlists.
