[MTD] NAND: nand_write_ecc memory and OOB corruption
Nathan Roberts noticed the nand_write_ecc index into oobbuf goes out of
bounds when crossing an erase block boundary, causing incorrect OOB data
to be written and corrupting memory. Reset the index to zero after
re-preparing oobbuf for a new erase block.

just read this "small" summary, where every information is stored which is

This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During
the mount process if there is no summary info the orignal scan process will
be executed. EBS works with NAND and NOR flashes, too.

[PATCH] nvidiafb: Geforce 7800 series support added
This adds support for the Nvidia Geforce 7800 series of cards to the
nvidiafb framebuffer driver. All it does is add the PCI device id for
the 7800, 7800 GTX, 7800 GO, and 7800 GTX GO cards to the module device
table for the nvidiafb.ko driver, so that nvidiafb.ko will actually work
on these cards.
I also added the relevant PCI device ids to linux/pci_ids.h
I tested it on my 7800 GTX here and it works like a charm. I now can
get framebuffer support on this card! Woo hoo!! Nothing like 200x75 text
mode to make your eyes BLEED. ;)
