87e92c062b [MTD] cfi_cmdset_0002.c: Add Macronix CFI V1.0 TopBottom detection
This patch adds TopBottom detection for most Macronix chips with CFI V1.0.

The main purpose of this patch is to add detection of the MX29LV400C B
used on the LaCie Ethernet Disk mini V2 NAS.

It detects the following parts correctly:-
MX28F640C3B T
MX29LV002C  B
MX29LV002NC B
MX29LV004C  T
MX29LV400C  T/B
MX29LV800C  T/B
MX29LV160C  T/B
MX29SL800C  T/B
MX29SL802C  T/B

It detects the following uniform part as bottom but it should work
correctly:-
MX29LV040C

For T parts it causes the erase block table to be reversed correctly.
For other parts it avoids the bogus "Assuming top" message.

It does not detect the following correctly:-
MX28F640C3B B
MX29LV002C  T
MX29LV002NC T
MX29LV004C  B
MX29SL400C  T/B
MX29SL402C  T/B

If desired I could supply a more complicated patch to handle these as
well.

Only the MX29LV400C B has been physically tested; others were checked
against their data sheets.

3fc2389847 [MTD] [NAND] Bug on atmel_nand HW ECC : OOB info not correctly written
The functions that write the OOB info (on hardware ECC only) use the 
HW_SYNDROME method.

This is not correct : the start position is "pos = eccsize + chunk" and 
should be eccsize. So, the standard (nand_write_oob_std) function should 
be used. This patch corrects this by using NAND_ECC_HW instead of 
NAND_ECC_HW_SYNDROME.

This has only been tested on small pages nand flash.
(if anyone can test it on large pages that would be great).

13f5369704 [MTD] [NAND] driver extension to support NAND on TQM85xx modules
This patch extends the FSL UPM NAND driver from Anton Vorontsov to
support hardware which does not have the R/B pin of the NAND chip
connected, like the TQM8548 module:

- The OF_GPIO dependency has been removed from the Kconfig option
  because GPIO is not needed. The relevant gpio_* function are then
  stubbed out in <linux/gpio.h>.

- It re-introduces the chip-delay property to define an appropriate
  maximum delay time (tR) required for read operations. The binding
  will be documented in a separate patch.

95ebffd749 [MTD] [NAND] fsl_upm: update driver for the new OF bindings
- Get rid of fsl,wait-pattern and fsl,wait-write. I think this isn't
  chip-specific, and we should always do waits. I saw one board that
  didn't need fsl,wait-pattern, but I assume this was the exception
  that proves the rule;
- Get rid of chip-delay. Today there are no users for this, and if
  anyone really need this they should push the OF bindings beforehand;
- Now flash chips should be child nodes of the FSL UPM NAND controller;
- Implement OF partition parsing.

63fd7f30f3 [MTD] [INFTL] Fix infinite loop in INFTL_foldchain
When iterating over a chain in reverse (oldest block first), this
patch correctly marks the PUtable[] entry of the second to last erase
block of a chain as BLOCK_NIL, regardless of whether or not it can
format the last block successfully. Before, the second to last block
was only marked as pointing to BLOCK_NIL if INFTL_formatblock()
succeeded on the last block of the chain, which could potentially
result in an infinite loop if the block was worn out and refused to
format.

0e4a008a4f UBI: fix IS_ERR test
In case of error, the function add_volume returns an ERR pointer. The
result of IS_ERR, which is supposed to be used in a test as it is, is

replace this test by a simple IS_ERR test.

43035338ad [MTD] [NAND] pxa3xx_nand: moved nand definitions into shared platform header
This patch moves the exported datastructures from the pxa3xx_nand.c driver
into the <mach/pxa3xx_nand.h> header. This is a plain movement without
any modification of the attributes.

This is the first one of a set of patches which:

 * allows to specify used NAND flash in the platform code and allows to turn
   off the old way to specify NAND characteristics in the driver.  This way did
   not worked well as these characteristics depend on the platform and can not be
   derived from NAND id alone.

   E.g.  some NAND chips share the same ID (e.g.  K9K8G08U0A and K9NBG08U5A) but
   have different timings (which are written in the common driver currently and
   must be modified there).

 * adds 'const' annotations at various places

Further patches will be sent to the mtd-list.

16ecf85a5c e1000: fix stack size
Here's the patch. It shrinks the stack from 1152 bytes to 192 bytes (the
first version, that only did the e1000_option part, got it down to 600
bytes). About half comes from not using multiple "e1000_option"
structures, the other half comes from turning the "e1000_opt_list[]"
arrays into "static const" instead, so that gcc doesn't copy them onto the
stack.

8560c650f3 Revert "pktcdvd: push BKL down into driver"
This reverts commit 5b6155ee70, because
the block device ioctl's really aren't ready for it.

In particular, the "struct file *" and the "struct inode *" arguments do
not necessarily match, which means that the unlocked version of the
ioctl (that only gets a "struct file *") isn't actually able to handle
the cases it needs to handle.

This fixes bugzilla

f2455eb176 wan: Missing capability checks in sbni_ioctl()
There are missing capability checks in the following code:

1300 static int
1301 sbni_ioctl( struct net_device  *dev,  struct ifreq  *ifr,  int  cmd)
1302 {
[...]
1319     case  SIOCDEVRESINSTATS :
1320         if( current->euid != 0 )    /* root only */
1321             return  -EPERM;
[...]
1336     case  SIOCDEVSHWSTATE :
1337         if( current->euid != 0 )    /* root only */
1338             return  -EPERM;
[...]
1357     case  SIOCDEVENSLAVE :
1358         if( current->euid != 0 )    /* root only */
1359             return  -EPERM;
[...]
1372     case  SIOCDEVEMANSIPATE :
1373         if( current->euid != 0 )    /* root only */
1374             return  -EPERM;

Here's my proposed fix:

Missing capability checks.
