Fix a couple drivers that do not correctly terminate their pci_device_id
lists. This results in garbage being spewed into modules.pcimap when the
module happens to not have 28 NULL bytes following the table, and/or the
last PCI ID is actually truncated from the table when calculating the
modules.alias PCI aliases, cause those unfortunate device IDs to not
auto-load.Signed-off-by: Kees Cook

The nand_base.c driver implicitly casts the uint32_t
eccpos array to 'int *', which is not only not guaranteed
to be the same sign as the source, but is not guaranteed
to be the same size.Fix by changing nand_base.c to use uint32_t
referencing the eccpos fields.Signed-off-by: Ben Dooks

When we mark block bad we have to get chip because this involves
writing to the page's OOB. We hit this bug in UBI - we observed
random obscure crashes when it marks block bad from the background
thread and there is some parallel task which utilizes flash.This patch also adds a TODO note about BBT table protection which
it seems does not exist.Signed-off-by: Artem Bityutskiy

I have made a tool to parse the kernel that does not pre-process the
source. That means that my parser tries to parse all the code, including
code in the #else branch or code that is not often compiled because the
driver is not very used (or not used at all). So, my parser sometimes
reports parse error not originally detected by gcc. Here is my (first)
patch.[akpm@linux-foundation.org: fix amd8111e.c]

I noticed that many source files include while they do
not appear to need it. Here is an attempt to clean it all up.In order to find all possibly affected files, I searched for all
files including but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:arch/alpha/kernel/err_common.c

The CAFÉ can handle two chip on separate chipselect lines. Hook up the
undocumented chipselect bits in the driver and probe both.In the case of OLPC, it's not actually two separate devices -- it's a
single '1GiB' package with two 512MiB dies internally. So clear the
NAND_BBT_PERCHIP flag to treat it as a single chip for BBT purposes, and
make life easier for the firmware.Signed-off-by: David Woodhouse

There is a slight bug in nand_default_block_markbad, where the offset is

During the MTD rework the oobavail parameter of mtd_info structure has become
private. This is not quite correct in terms of integrity and logic. If we have
means to write to OOB area, then we'd like to know upfront how many bytes out
