More atomic operation removal from page allocator Signed-off-by:
-
Nick Piggin authored
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 authored
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).

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:

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 authored
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 __exit Signed-off-by:

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.

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:

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.

__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 :( Cc: Paul Jackson <pj@sgi.com> Cc: Christoph Lameter <clameter@engr.sgi.com> Signed-off-by: -

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. Signed-off-by:

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).

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.

Redo the interupt handling of sky2 driver based on the IRQ mangement documentation. All interrupts are handled by the device0 NAPI poll routine. Don't need to adjust interrupt mask in IRQ context, done only when changing device under RTNL. Therefore don't need hwlock anymore. Signed-off-by:

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:
