2006-05-15[PATCH] setup_per_zone_pages_min() overflow fixAndrew Morton
As pointed out in http://bugzilla.kernel.org/show_bug.cgi?id=6490, this function can experience overflows on 32-bit machines, causing our response to changed values of min_free_kbytes to go whacky. Fixing it efficiently is all too hard, so fix it with 64-bit math instead.

With "Paul E. McKenney" <paulmck@us.ibm.com> Introduce rcu_needs_cpu() interface. This can be used to tell if there will be a new rcu batch on a cpu soon by looking at the curlist pointer.

2006-05-15[PATCH] VIA quirk fixup, additional PCI IDsChris Wedgwood
An earlier commit (75cf7456dd87335f574dcd53c4ae616a2ad71a11) changed an overly-zealous PCI quirk to only poke those VIA devices that need it. However, some PCI devices were not included in what I hope is now the full list. Consequently we're failing to run the quirk on all machines which need it, causing IRQ routing failures. This should I hope correct this. Thanks to Masoud Sharbiani <masouds@masoud.ir> for pointing this out and testing the fix.

2006-05-15[PATCH] autofs4: NFY_NONE wait race fixIan Kent
This patch fixes two problems. First, the comparison of entries in the waitq.c was incorrect. Second, the NFY_NONE check was incorrect. The test of whether the dentry is mounted if ineffective, for example, if an expire fails then we could wait forever on a non existant expire. The bug was identified by Jeff Moyer. The patch changes autofs4 to wait on expires only as this is all that's needed. If there is no existing wait when autofs4_wait is call with a type of NFY_NONE it delays until either a wait appears or the the expire flag is cleared.

2006-05-12Alternative fix for MMC oops on unmount after removalLinus Torvalds
Make sure to clear the driverfs_dev pointer when we do del_gendisk() (on disk removal), so that other users that may still have a ref to the disk won't try to use the stale pointer. Also move the KOBJ_REMOVE uevent handler up, so that the uevent still has access to the driverfs_dev data. This all should hopefully fix the problems with MMC umounts after device removals that caused commit 56cf6504fc1c0c221b82cebc16a444b684140fb7 and its reversal (1a2acc9e9214699a99389e323e6686e9e0e2ca67).

2006-05-12[NEIGH]: Fix IP-over-ATM and ARP interaction.Simon Kelley
The classical IP over ATM code maintains its own IPv4 <-> <ATM stuff> ARP table, using the standard neighbour-table code. The neigh_table_init function adds this neighbour table to a linked list of all neighbor tables which is used by the functions neigh_delete() neigh_add() and neightbl_set(), all called by the netlink code. Once the ATM neighbour table is added to the list, there are two tables with family == AF_INET there, and ARP entries sent via netlink go into the first table with matching family. This is indeterminate and often wrong. To see the bug, on a kernel with CLIP enabled, create a standard IPv4 ARP entry by pinging an unused address on a local subnet. Then attempt to complete that entry by doing ip neigh replace <ip address> lladdr <some mac address> nud reachable Looking at the ARP tables by using ip neigh show will reveal two ARP entries for the same address. One of these can be found in /proc/net/arp, and the other in /proc/net/atm/arp. This patch adds a new function, neigh_table_init_no_netlink() which does everything the neigh_table_init() does, except add the table to the netlink all-arp-tables chain. In addition neigh_table_init() has a check that all tables on the chain have a distinct address family. The init call in clip.c is changed to call neigh_table_init_no_netlink(). Since ATM ARP tables are rather more complicated than can currently be handled by the available rtattrs in the netlink protocol, no functionality is lost by this patch, and non-ATM ARP manipulation via netlink is rescued. A more complete solution would involve a rtattr for ATM ARP entries and some way for the netlink code to give neigh_add and friends more information than just address family with which to find the correct ARP table. [ I've changed the assertion checking in neigh_table_init() to not use BUG_ON() while holding neigh_tbl_lock. Instead we remember that we found an existing tbl with the same family, and after dropping the lock we'll give a diagnostic kernel log message and a stack dump. -DaveM ] Signed-off-by: Simon Kelley <simon@thekelleys.org.uk> Signed-off-by: David S.

2006-05-12Revert "[BLOCK] Fix oops on removal of SD/MMC card"Linus Torvalds
This reverts commit 56cf6504fc1c0c221b82cebc16a444b684140fb7. Both Erik Mouw and Andrew Vasquez independently pinpointed this commit as causing problems, where the slab cache for a driver is never released (most obviously causing problems when immediately re-loading that driver, resulting in a "kmem_cache_create: duplicate cache <xyz>" message, but it can also cause other trouble). James Bottomley dug into it, and reports: "OK, here's the scoop. The problem patch adds a get of driverfs_dev in add_disk(), but doesn't put it again until disk_release() (which occurs on final put_disk() of the gendisk). However, in SCSI, the driverfs_dev is the sdev_gendev. That means there's a reference held on sdev_gendev until final disk put. Unfortunately, we use the driver model driver_remove to trigger del_gendisk (which removes the gendisk from visibility and decrements the refcount), so we've introduced an unbreakable deadlock in the reference counting with this. I suggest simply reversing this patch at the moment. If Russell and Jens can tell me what they're trying to do I'll see if there's another way to do it." so hereby the patch gets reverted, waiting for a better fix.

2006-05-12[PATCH] USB: Emagic USB firmware loading fixesMonty
It's become apparent as machines get faster that the emagic kernel firmware loaders (based on the ezusb loader) have a reset race. a 400MHz TiBook never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the time. The bug is seen as a hung USB box and the kernel error: drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware: error = -110 The patch below inserts a delay after deasserting reset to allow the box to settle before a new command is issued.

2006-05-11[BLOCK] limit request_fn recursionJens Axboe
Don't recurse back into the driver even if the unplug threshold is met, when the driver asks for a requeue. This is both silly from a logical point of view (requeues typically happen due to driver/hardware shortage), and also dangerous since we could hit an endless request_fn -> requeue -> unplug -> request_fn loop and crash on stack overrun. Also limit blk_run_queue() to one level of recursion, similar to how blk_start_queue() works.

2006-05-10sis900: phy for FoxCon motherboardJames Cameron
661FX7MI-S motherboard which uses the SiS 661FX chipset. The patch adds an entry to mii_chip_info for the transceiver. The PHY ids were found using the sis900_c_122.diff patch from http://brownhat.org/sis900.html but that patch didn't solve the problem, because the PHY at address 1 was already being chosen. Without my patch, when bursts of packets arrive from other hosts on a LAN, the interface dropped one roughly 10% of the time, causing retransmits. There were fifth second pauses in refresh of large xterms, and it made Netrek suck. I can provide further test data. Workaround in lieu of patch is to use mii-tool to advertise 100baseTx-HD, then force renegotiation. I wasn't able to identify the actual transceiver, so the description field is a guess. This patch is similar to Artur Skawina's patch: http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2 I'm not sure, but I wonder if it means the default behaviour should be changed, so as to better handle future transceivers.

2006-05-10[Cardman 40x0] Fix udev device creationHarald Welte
This patch corrects the order of the calls to register_chrdev() and pcmcia_register_driver(). Now udev correctly creates userspace device files /dev/cmmN and /dev/cmxN respectively.

Now that netdevice sysfs registration is done as part of register_netdevice; bridge code no longer has to be tricky when adding it's kobjects to bridges. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-05-10[NET]: Do sysfs registration as part of register_netdevice.Stephen Hemminger
The last step of netdevice registration was being done by a delayed call, but because it was delayed, it was impossible to return any error code if the class_device registration failed. Side effects: * one state in registration process is unnecessary. * register_netdevice can sleep inside class_device registration/hotplug * code in netdev_run_todo only does unregistration so it is simpler.
