Use a repeated read_byte() instead of read_buf(), since for x16 buswidth
devices, we need to avoid the upper I/O[16:9] bits. See the following
commit for reference:

Author: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

    mtd: nand: don't use {read,write}_buf for 8-bit transfers

Now, I think that all barriers to probing ONFI on x16 devices are
removed, so remove the check from nand_flash_detect_onfi().

Tested on 8-bit ONFI NAND (Micron MT29F32G08CBADAWP).

The NAND command helpers tend to automatically shift the column address
for x16 bus devices, since most commands expect a word address, not a
byte address. The Read ID command, however, expects an 8-bit address
(i.e., 0x00, 0x20, or 0x40 should not be translated to 0x00, 0x10, or
0x20).

This fixes the column address for a few drivers which imitate the
nand_base defaults. Note that I don't touch sh_flctl.c, since it already
handles this problem slightly differently (note its comment "READID is
always performed using an 8-bit bus").

I have not tested this patch, as I only have x8 parts up for testing at
this point. Hopefully that can change soon...

The patch converts the arrays to buffer pointers for nand_buffers{}.

The cafe_nand.c is the only NAND_OWN_BUFFERS user which allocates
nand_buffers{} itself.

This patch disables the DMA for nand_scan_ident, and restores the DMA
status after we finish the nand_scan_ident. This way, we can get page
size and OOB size and use them to allocate cafe->dmabuf.

Since the cafe_nand.c uses the NAND_ECC_HW_SYNDROME ECC mode, we do not
allocate the buffers for @ecccalc and @ecccode.

Commit b2a2a84d (mtd: phram: dot not crash when

patch to block2mtd" (c4e7fb31), but it has
missed the crucial point of the original path: all these "if(n)def MODULE".
It has broken the possibility to create several phram instances when phram is
compiled as module. The possibility to add instances via /sys writes to
/sys/module/phram/parameters/phram was also broken with mentioned patch.
Proposed patch takes the idea of original block2mtd patch to its full extent.
Assumption "This function is always called before 'init_phram()'" was also
incorrect, so removed the comment. This patch effectively reverts also

  staging/cxt1e1/linux.c: Correct arbitrary memory write in c4_ioctl()

This fixes CVE-2014-0102.

The following command sequence produces an oops:

	keyctl new_session
	i=`keyctl newring _ses @s`
	keyctl link @s $i

The problem is that search_nested_keyrings() sees two keyrings that have
matching type and description, so keyring_compare_object() returns true.
s_n_k() then passes the key to the iterator function -
keyring_detect_cycle_iterator() - which *should* check to see whether this is
the keyring of interest, not just one with the same name.

Because assoc_array_find() will return one and only one match, I assumed that
the iterator function would only see an exact match or never be called - but
the iterator isn't only called from assoc_array_find()...

The oops looks something like this:

	kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003!
	invalid opcode: 0000 [#1] SMP
	...
	RIP: keyring_detect_cycle_iterator+0xe/0x1f

	  keyctl_keyring_link+0x60/0x81
	  SyS_keyctl+0x65/0xe4
	  tracesys+0xdd/0xe2

The fix is to make keyring_detect_cycle_iterator() check that the key it
has is the key it was actually looking for rather than calling BUG_ON().

A testcase has been included in the keyutils testsuite for this:

   those machines.  From Kieran Clancy.

 - If the ACPI sleep control and status registers are not present (which

Pull tracing fix from Steven Rostedt:
 "In the past, I've had lots of reports about trace events not working.
  Developers would say they put a trace_printk() before and after the
  trace event but when they enable it (and the trace event said it was
  enabled) they would see the trace_printks but not the trace event.

  I was not able to reproduce this, but that's because I wasn't looking
  at the right location.  Recently, another bug came up that showed the
  issue.

  If your kernel supports signed modules but allows for non-signed
  modules to be loaded, then when one is, the kernel will silently set
  the MODULE_FORCED taint on the module.  Although, this taint happens
  without the need for insmod --force or anything of the kind, it labels
  the module with that taint anyway.

  If this tainted module has tracepoints, the tracepoints will be
  ignored because of the MODULE_FORCED taint.  But no error message will
  be displayed.  Worse yet, the event infrastructure will still be
  created letting users enable the trace event represented by the
  tracepoint, although that event will never actually be enabled.  This
  is because the tracepoint infrastructure allows for non-existing
  tracepoints to be enabled for new modules to arrive and have their
  tracepoints set.

  Although there are several things wrong with the above, this change
  only addresses the creation of the trace event files for tracepoints
  that are not created when a module is loaded and is tainted.  This
  change will print an error message about the module being tainted and
  not the trace events will not be created, and it does not create the
  trace event infrastructure"

Pull device mapper fixes from Mike Snitzer:

 - dm-cache memory allocation failure fix
 - fix DM's Kconfig identation
 - dm-snapshot metadata corruption fix for bug introduced in 3.14-rc1
 - important refcount < 0 fix for the DM persistent data library's space
   map metadata interface which fixes corruption reported by a few
   dm-thinp users

and last but not least:

 - more extensive fixes than ideal for dm-thinp's data resize capability
   (which has had growing pain much like we've seen from -ENOSPC
   handling of filesystems that mature).

   The end result is dm-thinp now handles metadata operation failure and
   no data space error conditions much better than before.

* tag 'dm-3.14-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
  dm space map metadata: fix refcount decrement below 0 which caused corruption
  dm thin: fix Documentation for held metadata root feature
  dm thin: fix noflush suspend IO queueing
  dm thin: fix deadlock in __requeue_bio_list
  dm thin: fix out of data space handling
  dm thin: ensure user takes action to validate data and metadata consistency
  dm thin: synchronize the pool mode during suspend
  dm snapshot: fix metadata corruption
  dm: fix Kconfig indentation
  dm cache mq: fix memory allocation failure for large cache devices
