Function ubifs_dump_node() has been modified to avoid memory oob
accessing while dumping node, node length (corresponding to the
size of allocated memory for node) should be passed into all node
dumping callers.

This reverts commit acc5af3e ("ubifs: Fix out-of-bounds memory access caused by abnormal value of node_len")

No need to avoid memory oob in dumping for data node alone. Later, node
length will be passed into function 'ubifs_dump_node()' which replaces
all node dumping places.

To prevent memory out-of-bounds accessing in ubifs_dump_node(), actual
dumping length should be restricted by another condition(size of memory
which is allocated for the node).

This patch handles following situations (These situations may be caused
by bit flipping due to hardware error, writing bypass ubifs, unknown
bugs in ubifs, etc.):
1. bad node_len: Dumping data according to 'ch->len' which may exceed
   the size of memory allocated for node.
2. bad node content: Some kinds of node can record additional data, eg.
   index node and orphan node, make sure the size of additional data
   not beyond the node length.
3. node_type changes: Read data according to type A, but expected type
   B, before that, node is allocated according to type B's size. Length
   of type A node is greater than type B node.

This is because since ec10a24f, the option parsing happens before
fill_super and so the MTD device isn't associated with the filesystem.

For NOR flashes EC and VID are zeroed out before an erase is issued to
make sure UBI does not mistakenly treat the PEB as used and associate it
with an LEB.

But on some flashes, like the Cypress Semper S28 SPI NOR flash family,
multi-pass page programming is not allowed on the default ECC scheme.
This means zeroing out these magic numbers will result in the flash
throwing a page programming error.

Do not zero out EC and VID for such flashes. A writesize > 1 is an
indication of an ECC-ed flash.

Write buffers use a kmalloc()'ed buffer, they can leak
up to seven bytes of kernel memory to flash if writes are not
aligned.
So use ubifs_pad() to fill these gaps with padding bytes.
This was never a problem while scanning because the scanner logic
manually aligns node lengths and skips over these gaps.

Set rp_size to zero will be ignore during remounting.

The jffs2 mount options will be ignored when remounting jffs2.
It can be easily reproduced with the steps listed below.
1. mount -t jffs2 -o compr=none /dev/mtdblockx /mnt
2. mount -o remount compr=zlib /mnt

Since ec10a24f, the option parsing happens before fill_super and
then pass fc, which contains the options parsing results, to function
jffs2_reconfigure during remounting. But function jffs2_reconfigure do
not update c->mount_opts.

This patch add a function jffs2_update_mount_opts to fix this problem.

By the way, I notice that tmpfs use the same way to update remounting
options. If it is necessary to unify them?

The log of this problem is:
jffs2: Error garbage collecting node at 0x***!
jffs2: No space for garbage collection. Aborting GC thread

This is because GC believe that it do nothing, so it abort.

After going over the image of jffs2, I find a scene that
can trigger this problem stably.
The scene is: there is a normal dirent node at summary-area,
but abnormal at corresponding not-summary-area with error
name_crc.

The reason that GC exit abnormally is because it find that
abnormal dirent node to GC, but when it goes to function
jffs2_add_fd_to_list, it cannot meet the condition listed
below:

if ((*prev)->nhash == new->nhash && !strcmp((*prev)->name, new->name))

So no node is marked obsolete, statistical information of
erase_block do not change, which cause GC exit abnormally.

The root cause of this problem is: we do not check the
name_crc of the abnormal dirent node with summary is enabled.

Noticed that in function jffs2_scan_dirent_node, we use
function jffs2_scan_dirty_space to deal with the dirent
node with error name_crc. So this patch add a checking
code in function read_direntry to ensure the correctness
of dirent node. If checked failed, the dirent node will
be marked obsolete so GC will pass this node and this
problem will be fixed.

Pull mtd fixes from Miquel Raynal:
 "Because of a recent change in the core, NAND controller drivers
  initializing the ECC engine too early in the probe path are broken.

  Drivers should wait for the NAND device to be discovered and its
  memory layout known before doing any ECC related initialization, so
  instead of reverting the faulty change which is actually moving in the
  right direction, let's fix the drivers directly: socrates, sharpsl,
  r852, plat_nand, pasemi, tmio, txx9ndfmc, orion, mpc5121, lpc32xx_slc,
  lpc32xx_mlc, fsmc, diskonchip, davinci, cs553x, au1550, ams-delta,

Pull drm fixes from Dave Airlie:
 "Unfortunately this has a bit of thanksgiving stuffing in it, as it a
  bit larger (at least the vc4 patches) than I like at this point in
  time.

  The main thing is it has a bunch of regressions fixes for reports in
  the last couple of weeks, ast, nouveau and the amdgpu ttm init fix,
  along with the usual selection of amdgpu and i915 fixes.

  The vc4 fixes are a few but they are fixes and the nastiest one is a
  fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
  that range and there isn't enough shielding and interference happen
  between the two, the fix adjusts the mode clock to try and avoid the
  wifi channels in that case.

  Hopefully you can merge this between turkey slices, and next week
  should be quieter.

  ast:
   - LUT loading regression fix

  nouveau:
   - relocations regression fix

  amdgpu:
   - ttm init oops fix
   - Runtime pm fix
   - SI UVD suspend/resume fix
   - HDCP fix for headless cards
   - Sienna Cichlid golden register update

  i915:
   - Fix Perf/OA workaround register corruption (Lionel)
   - Correct a comment statement in GVT (Yan)
   - Fix GT enable/disable iterrupts, including a race condition that
     prevented GPU to go idle (Chris)
   - Free stale request on destroying the virtual engine (Chris)

  exynos:
   - config dependency fix

  mediatek:
   - unused var removal
   - horizonal front/back porch formula fix

  vc4:
   - wifi and hdmi interference fix
   - mode rejection fixes
   - use after free fix
   - cleanup some code"
