More atomic operation removal from page allocator

In the page release paths, we can be sure that nobody will mess with our
page->flags because the refcount has dropped to 0. So no need for atomic
operations here.Signed-off-by: Nick Piggin

If vmscan finds a zero refcount page on the lru list, never ClearPageLRU
it. This means the release code need not hold ->lru_lock to stabilise
PageLRU, so that lock may be skipped entirely when releasing !PageLRU pages
(because we know PageLRU won't have been temporarily cleared by vmscan,
which was previously guaranteed by holding the lock to synchronise against
vmscan).Signed-off-by: Nick Piggin

Do not use platform_device_register_simple() as it is going away, define
dcdbas_driver and implement ->probe() and ->remove() functions so manual
binding and unbinding will work with this driver.Also switch to using attribute_group when creating sysfs attributes and
make sure to check and handle errors; explicitely remove attributes when
detaching driver.Signed-off-by: Dmitry Torokhov

mv64x600_wdt: convert to the new platform device interface Do not use
platform_device_register_simple() as it is going away.Signed-off-by: Dmitry Torokhov

Signed-off-by: Linus Torvalds -
The patch does the following for v441xx seris drivers:
- stop using platform_device_register_simple() as it is going away
- mark ->probe() and ->remove() methods as __devinit and __devexit
respectively
- initialize "owner" field in driver structure so there is a link
from /sys/modules to the driver
- mark *_init() and *_exit() functions as __init and __exitSigned-off-by: Dmitry Torokhov

Sam's tree includes a new check, which found that we're exporting strpbrk()
multiple times.It seems that the convention is that this is exported from the arch files, so
reove the lib/string.c export.Cc: Sam Ravnborg

Update the serial_txx9 driver.
* More strict check in verify_port. Cleanup.
* Do not insert a char caused previous overrun.
* Fix some spin_locks.
* Do not call uart_add_one_port for absent ports.Also, this patch removes a BROKEN tag from Kconfig. This driver has been
marked as BROKEN by removal of uart_register_port, but it has been solved
already on Sep 2005.Signed-off-by: Atsushi Nemoto

The code that handles bios that span table target boundaries by breaking
them up into smaller bios will not split an individual struct bio_vec into
more than two pieces. Sometimes more than that are required.This patch adds a loop to break the second piece up into as many pieces as
are necessary.Cc: "Abhishek Gupta"

__get_page_state() has an open-coded for_each_cpu_mask() loop in it.
Tidy that up, then notice that the code was buggy:
while (cpu < NR_CPUS) {
unsigned long *in, *out, off;if (!cpu_isset(cpu, *cpumask))
continue;an obvious infinite loop. I guess we just never call it with a holey cpu
mask.Even after my cpumask size-reduction work, this patch increases code size :(

If a file is not found in v9fs_vfs_lookup, the function creates negative
dentry, but doesn't assign any dentry ops. This leaves the negative entry
in the cache (there is no d_delete to mark it for removal). If the file is
created outside of the mounted v9fs filesystem, the file shows up in the
directory with weird permissions.This patch assigns the default v9fs dentry ops to the negative dentry.

Remove the sleep_avg multiplier. This multiplier was necessary back when
we had 10 seconds of dynamic range in sleep_avg, but now that we only have
one second, it causes that one second to be compressed down to 100ms in
some cases. This is particularly noticeable when compiling a kernel in a
slow NFS mount, and I believe it to be a very likely candidate for other
recently reported network related interactivity problems.In testing, I can detect no negative impact of this removal.

All accessor's different methods are now selected with C code and unused
ones statically optimized away at compile time instead of being selected
with #if's and #ifdef's. This has many advantages such as allowing the
compiler to validate the syntax of the whole code, making it cleaner and
easier to understand, and ultimately allowing people to define
configuration symbols in terms of variables if they really want to
dynamically support multiple bus configurations at the same time (with
the unavoidable performance cost).Signed-off-by: Nicolas Pitre

Boards with multiple PHYs were not being handled properly by the pcnet32
driver. This patch by Thomas Bogendoerfer with changes by me will allow
Allied Telesyn 2700FTX and 2701FTX boards to use either the copper or
the fiber interfaces. It has been tested on ia32 and ppc64 hardware.
Philippe Seewer also tested and improved the patch.
ethtool for pcnet32 already supports multiple phys.See also bugzilla bug 4219.
Please apply to 2.6.16

The Yukon EC/rev0 (A1) chipset requires a bunch of workarounds. I copied these
from sk98lin. But since they never got tested and add more cruft to the code;
any attempt at using driver as is on this version will probably fail.It looks like this was a early engineering sample chip revision, if it ever shows
up on a real system. Produce an error message.Signed-off-by: Stephen Hemminger
