Need to use list_for_entry_safe(), as we're removing items during the
traversal. list_for_each_entry() uses the first ptr also as an iterator, if
you kfree() it slab takes it, might poison it and then you try to use it to
iterate to the next object in list.

Fix the p-persistence CSMA algorithm which in simplex mode was starting
with a slottime delay before doing anything else as if there was carrier
collision resulting in bad performance on simplex links.

Patch from Ben Dooks
Rename the s3c2410_report_oc() to s3c2410_usb_report_oc()
as this is an usb specific function.
Change port power on the usb-simtec implementation to only
power up the output if both are set, as per the usb 1.1
specification

Unfortunately, we can't use the "user" bit in the page tables to
control whether a page table entry is "global" or "asid" specific,
since the vector page is mapped as "user" accessible but is not
process specific.
Therefore, give direct control of the ARMv6 "nG" (not global)
bit to the mm layers.

This patch removes the tda9887 stuff from lgdt330x.c. It's experimental code
which wasn't supposed to leak out and we don't want it in 2.6.13.

From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com>
sendmsg()/recvmsg() syscalls from o32/n32 apps to a 64bit kernel will
cause a kernel memory leak if iov_len > UIO_FASTIOV for each syscall!
This is because both sys_sendmsg() and verify_compat_iovec() kmalloc a
new iovec structure. Only the one from sys_sendmsg() is free'ed.
I wrote a simple test program to confirm this after identifying the
problem:
http://davej.org/programs/testsendmsg.c
Note that the below fix will break solaris_sendmsg()/solaris_recvmsg() as
it also calls verify_compat_iovec() but expects it to malloc internally.
[ I fixed that. -DaveM ]

envctrl currently uses very odd ways to stop a thread, using various

This patch (which is untested as I don't have sparc hardware) switches
it to use the proper kthread infrastructure.

Remove new configuration API from i2o_config
The API-patch is still available from the I2O website (which is mentioned in
the kernel config now). It is removed because it creates a new binary
sysfs-attribute, which doesn't have the limitiation of 4k. Expect for the
Adaptec controllers, which has a limitation in the hardware this attribute
doesn't make sense anywhere else. Until the sysfs API provides an attribute
which doesn't buffer (like firmware) and let access to at least 64k blocks i
provide a separate patch...
(akpm: basically, this API was introduced post-2.6.12 and Markus wants to pull
it out before 2.6.13).
