[PATCH 42/56] fs/ubifs: support compiling out splice

Compile out splice support from ubifs when the splice-family of syscalls is not
supported by the system (i.e. CONFIG_SYSCALL_SPLICE is undefined).

Hi, I'm having trouble with this patch using a Cadence QSPI controller and
Micron n25q00 part.

I can use quad commands in Extended SPI mode, but I can't make this EVCR Quad
mode work.

The Cadence QSPI Controller has fields to configure the quad transfer, and can
support quad opcode, quad address, and quad data, or some combination.  There
is a chart in the docs which shows the combinations for various read commands.

Problem is, I've tried all of the combinations and all I get is FF with this
EVCR patch.

If I don't set the quad mode in the EVCR, then I can use quad read commands no
problem.

Bottom line, with the Cadence QSPI controller, if I use quad commands in
Extended SPI mode, then all good.  If I use this EVCR quad mode, then all bad.

Anybody else have a Cadence QSPI controller and using EVCR quad mode
successfully?

[PATCH] mtd: gpmi: Remove noisy error message

mx28evk board has a socket for NAND flash that comes with no NAND flash
populated, and then we get this message on every boot:

[    1.657603] gpmi-nand 8000c000.gpmi-nand: driver registration failed: -19

,which is not very helpful, so get rid of this error message.

[PATCH] mtd: cafe_nand: drop duplicate .write_page implementation

This write_page() function is functionally equivalent to the default in
nand_base.c. Its only difference is in subpage programming support,
which cafe_nand.c does not advertise, so the difference is negligible.
