Update documentation for the hw_random support to be current:
- Documentation/hw_random.txt has been updated to reflect the
current code: it's a framework now, a "core" with a small
sysfs interface, that hardware-specific drivers plug in to.
Text specific to Intel hardware is now at the end.- Kconfig now references the Documentation/hw_random.txt file
and better explains what this really does.Both chunks of documentation now higlight the fact that the kernel entropy
pool is maintained by "rngd", and this driver has nothing directly to do with
that important task.Signed-off-by: David Brownell

The block2mtd driver (drivers/mtd/devices/block2mtd.c) will kfree an on-stack
pointer when handling an invalid argument line (e.g.
block2mtd=/dev/loop0,xxx).The kfree was added some time ago when "name" was dynamically allocated.

[ 773.908954] Badness at net/core/dev.c:2204
...If we loop more than once in gem_poll(), we'll
use more than the real budget in our gem_rx()
calls, thus eventually trigger the caller's

Suppressing uevents turned out to be a bad idea as it screws up the
order of events, making user space very confused. Change the system to
use sysfs groups instead.This is a regression that, for some odd reason, has gone unnoticed for
some time. It confuses hal so that the block devices (which have the
mmc device as a parent) are not registered. End result being that
desktop magic when cards are inserted won't work.Signed-off-by: Pierre Ossman

PNP_MAX_MEM and PNP_MAX_PORT are mainly used to size tables of PNP
device resources. In 2.6.24, we increased their values to accomodate
ACPI devices that have many resources:2.6.23 2.6.24
------ ------
PNP_MAX_MEM 4 12
PNP_MAX_PORT 8 40However, ISAPNP also used these constants as the size of parts of the
logical device register set. This register set is fixed by hardware,
so increasing the constants meant that we were reading and writing
unintended parts of the register set.This patch changes ISAPNP to use the correct register set sizes (the
same values we used prior to 2.6.24).Signed-off-by: Bjorn Helgaas

The AT DMA handler of the request was occasionally executed after the
AR DMA handler of the response. The AT DMA handler then accessed an
already freed packet.Reported by Johannes Berg.

In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that
involved converting !x & y to !(x & y). The code below shows the same
pattern, and thus should perhaps be fixed in the same way.This is not tested and clearly changes the semantics, so it is only
something to consider.The semantic patch that makes this change is as follows:
