Tejun Heo 58a69cb47e workqueue, freezer: unify spelling of 'freeze' + 'able' to 'freezable'
There are two spellings in use for 'freeze' + 'able' - 'freezable' and
'freezeable'.  The former is the more prominent one.  The latter is
mostly used by workqueue and in a few other odd places.  Unify the
spelling to 'freezable'.

Maxim Levitsky 9bf70717a5 mtd: r852: remove useless pci powerup/down from suspend/resume routines
It turns out that pci core now handles these, so this code is redundant
and can even cause bugs

Maxim Levitsky ac373f7e22 mtd/r852: update card detect early.
This turns out to be the reason for DMA timeouts on resume,
if card was inserted while system was suspended

Maxim Levitsky 9489be8ca2 mtd/r852: Fixes in case of DMA timeout
* Don't call complete on dma completion
* do a INIT_COMPLETE before using it each time
* Report DMA read error via ecc 'correct'

I finally managed to make my system do suspend to ram propertly, and I see that
if card was inserted during suspend (while system was off), I get dma timeouts
on resume. Simple card reinsert solves the issue.
This patch solves a crash that would happen otherwise

Maxim Levitsky c3611570dd mtd: sm_common: split smartmedia and xD table
2GB xD card, and 4MB SmartMedia ROM card share same ID, so to make both work
split xD and smartmedia ID tables.

Hardware driver must be able to know which type it handles (and probably just one).

Randy Dunlap f696aa43fa mtd/nand/r852: fix build for CONFIG_PCI disabled
r852 fails to build when CONFIG_PCI is not enabled since it uses
pci_*() calls and is a PCI driver, so it should depend on PCI
to prevent build errors.
It should also #include <linux/pci.h>.

Maxim Levitsky fb45d3232c mtd: r852: Few fixes for problems that occur when card is rapidly inserted/removed.
First don't enable card detection logic to early. Second be very careful with
DMA engine, to be sure it doesn't write to kernel memory driver doesn't own.

Maxim Levitsky 67e054e919 mtd: nand: Add driver for Ricoh xD/SmartMedia reader
This adds a driver for Ricoh R5C852 xD card reader.

This reader is a part of larger mulifunction chip
and found at least in R5C832

Driver is complete, but bewere of the fact that some
(probably only type M) xD cards are 'fake' which means that
they have an on board CPU and expose emulated nand command set

These cards don't even store the  oob area on the flash,
but generate it on the fly from something else.

Thus they demand to have proper values written in the oob area,
and therefore only useful with SmartMedia FTL.
