| * sdhci: make isr tolerant of read errorsMark Lord2007-03-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt is shared with another device, which resumes earlier than the sdhci controller, and generates an interrupt. The sdhci interrupt handler runs, sees 0xffffffff in its own device's interrupt status, and tries to handle it.. The reason for the 0xffffffff is that the device is still suspended, and *all* regs are reading back 0xffffffff.

| | | | | | | | | | | | | | | | | | The new high-speed timings are similar to each other and the old system, but not identical. And although things "just work" most of the time, sometimes it does not. So we need to start marking which hosts are known to fully comply with the new timings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were using the platform_device.id field to identify which ethernet port is used for mv643xx_eth device. This is not generally correct. It will be incorrect, for example, if a hardware platform uses a single port but not the first port. Here, we add an explicit port_number field to struct mv643xx_eth_platform_data. This makes the mv643xx_eth_platform_data structure required, but that isn't an issue since all users currently provide it already.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCnet32 driver always passed the the size of the largest possible packet to the pci_dma_sync_single_for_cpu and pci_dma_sync_single_for_device. This results in a fairly large "colateral damage" in the caches and makes the flush operation itself much slower. On a system with a 40MHz CPU this patch increases network bandwidth by about 12%.

| * | bonding: Improve IGMP join processingJay Vosburgh2007-03-063-51/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In active-backup mode, the current bonding code duplicates IGMP traffic to all slaves, so that switches are up to date in case of a failover from an active to a backup interface. If bonding then fails back to the original active interface, it is likely that the "active slave" switch's IGMP forwarding for the port will be out of date until some event occurs to refresh the switch (e.g., a membership query). This patch alters the behavior of bonding to no longer flood IGMP to all ports, and to issue IGMP JOINs to the newly active port at the time of a failover. This insures that switches are kept up to date for all cases. "GOELLESCH Niels" <niels.goellesch@eurocontrol.int> originally reported this problem, and included a patch. His original patch was modified by Jay Vosburgh to additionally remove the existing IGMP flood behavior, use RCU, streamline code paths, fix trailing white space, and adjust for style.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bonding can erroneously register the same packet_type to receive ARPs (for use by ARP validation): once at device open time, and once via sysfs. Since sysfs can change the validate setting (and thus register or unregister) at any time, a flag is needed to synchronize with device open in order to avoid double registrations, and the simplest place is within the packet_type structure itself. Double unregister is not an issue. Bug reported by Ulrich Oelmann <ulrich.oelmann@web.de>. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* | [PATCH] knfsd: provide sunrpc pool_mode module optionGreg Banks2007-03-062-19/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to choose the mode for mapping NFS thread service pools to CPUs. Values are: auto choose a mapping mode heuristically global (default, same as the pre-2.6.19 code) a single global pool percpu one pool per CPU pernode one pool per NUMA node Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch makes the default "global". The pool mode can be changed after boot/modprobe using /sys, if the NFS and lockd services have been shut down. A useful side effect of this change is to fix a small memory leak when unloading the module.

* | [PATCH] knfsd: fix recently introduced problem with shutting down a busy NFS ↵NeilBrown2007-03-063-14/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | server When the last thread of nfsd exits, it shuts down all related sockets. It currently uses svc_close_socket to do this, but that only is immediately effective if the socket is not SK_BUSY. If the socket is busy - i.e. if a request has arrived that has not yet been processes - svc_close_socket is not effective and the shutdown process spins. So create a new svc_force_close_socket which removes the SK_BUSY flag is set and then calls svc_close_socket. Also change some open-codes loops in svc_destroy to use list_for_each_entry_safe.

* | [PATCH] knfsd: use recv_msg to get peer address for NFSD instead of code-copyingNeilBrown2007-03-061-32/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sunrpc server code needs to know the source and destination address for UDP packets so it can reply properly. It currently copies code out of the network stack to pick the pieces out of the skb. This is ugly and causes compile problems with the IPv6 stuff. So, rip that out and use recv_msg instead. This is a much cleaner interface, but has a slight cost in that the checksum is now checked before the copy, so we don't benefit from doing both at the same time. This can probably be fixed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the way we determine if a logical volume is larger than 2TB. The original test looked for a total_size of 0. Originally we added 1 to the total_size. That would make our read_capacity return size 0 for >2TB lv's. We assumed that we could not have a lv size of 0 so it seemed OK until we were in a clustered system. The backup node would see a size of 0 due to the reservation on the drive. That caused the driver to switch to 16-byte CDB's which are not supported on older controllers. After that everything was broken. It may seem petty but I don't see the value in trying to determine if the LBA is beyond the 2TB boundary. That's why when we switch we use 16-byte CDB's for all read/write operations. Please consider this for inclusion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TIMER_SOFTIRQ runs the hrtimers during bootup until a usable clocksource and clock event sources are registered. The switch to high resolution mode happens inside of the TIMER_SOFTIRQ, but runs the softirq afterwards. That way the tick emulation timer, which was set up in the switch to highres might be executed in the softirq context, which is a BUG. The rbtree has not to be touched by the softirq after the highres switch. This BUG was observed by Andres Salomon, who provided the information to debug it. Return early from the softirq, when the switch was sucessful.

* | [PATCH] i386: make x86_64 tsc header require i386 rather than vice-versaAndres Salomon2007-03-062-68/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to commit 95492e4646e5de8b43d9a7908d6177fb737b61f0 ([PATCH] x86: rewrite SMP TSC sync code), the headers in asm-i386 did not really require anything in include/asm-x86_64. This means that distributions such as fedora did not include asm-x86_64 in kernel-devel headers for i386. Ingo's commit changed that, and broke things. This is easy enough to hack around in package builds by just including asm-x86_64 on i386, but that's kind of annoying. If anything, x86_64 should depend upon i386, not the other way around. This patch changes it so that asm-x86_64/tsc.h includes asm-i386/tsc.h, rather than vice-versa.

* | [PATCH] Save/restore periodic tick information over suspend/resumeThomas Gleixner2007-03-064-0/+78
|/ | | | | | | | | | | | | | | | The programming of periodic tick devices needs to be saved/restored across suspend/resume - otherwise we might end up with a system coming up that relies on getting a PIT (or HPET) interrupt, while those devices default to 'no interrupts' after powerup. (To confuse things it worked to a certain degree on some systems because the lapic gets initialized as a side-effect of SMP bootup.) This suspend / resume thing was dropped unintentionally during the last-minute -mm code reshuffling.
