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%.

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to the original active interface, it is likely that the "active slave" switch's IGMP forwarding for the port will be out of date until some event occurs to refresh the switch (e.g., a membership query).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: NJay Vosburgh <fubar@us.ibm.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

there's a new NMI watchdog related problem: KVM crashes on certain bzImages because ... we enable the NMI watchdog by default (even if the user does not ask for it) , and no other OS on this planet does that so KVM doesnt have emulation for that yet. So KVM injects a #GP, which crashes the Linux guest: general protection fault: 0000 [#1] PREEMPT SMP Modules linked in: CPU: 0 EIP: 0060:[<c011a8ae>] Not tainted VLI EFLAGS: 00000246 (2.6.20-rc5-rt0 #3) EIP is at setup_apic_nmi_watchdog+0x26d/0x3d3 and no, i did /not/ request an nmi_watchdog on the boot command line! Solution: turn off that darn thing! It's a debug tool, not a 'make life harder' tool!! with this patch the KVM guest boots up just fine. And with this my laptop (Lenovo T60) also stopped its sporadic hard hanging (sometimes in acpi_init(), sometimes later during bootup, sometimes much later during actual use) as well. It hung with both nmi_watchdog=1 and nmi_watchdog=2, so it's generally the fact of NMI injection that is causing problems, not the NMI watchdog variant, nor any particular bootup code.

Doing something like this on a two cpu system # echo 0 > /sys/devices/system/cpu/cpu0/online # echo 1 > /sys/devices/system/cpu/cpu0/online # echo 0 > /sys/devices/system/cpu/cpu1/online will give me this: ======================================================= [ INFO: possible circular locking dependency detected ] 2.6.21-rc2-g562aa1d4-dirty #7 ------------------------------------------------------- bash/1282 is trying to acquire lock: (&cpu_base->lock_key){.+..}, at: [<000000000005f17e>] hrtimer_cpu_notify+0xc6/0x240 but task is already holding lock: (&cpu_base->lock_key#2){.+..}, at: [<000000000005f174>] hrtimer_cpu_notify+0xbc/0x240 which lock already depends on the new lock. This happens because we have the following code in kernel/hrtimer.c: migrate_hrtimers(int cpu) [...] old_base = &per_cpu(hrtimer_bases, cpu); new_base = &get_cpu_var(hrtimer_bases); [...] spin_lock(&new_base->lock); spin_lock(&old_base->lock); Which means the spinlocks are taken in an order which depends on which cpu gets shut down from which other cpu. Therefore lockdep complains that there might be an ABBA deadlock. Since migrate_hrtimers() gets only called on cpu hotplug it's safe to assume that it isn't executed concurrently on a The same problem exists in kernel/timer.c: migrate_timers(). As pointed out by Christian Borntraeger one possible solution to avoid the locking order complaints would be to make sure that the locks are always taken in the same order. E.g. by taking the lock of the cpu with the lower number first. To achieve this we introduce two new spinlock functions double_spin_lock and double_spin_unlock which lock or unlock two locks in a given order.

This patch resolves the issue found here: http://bugme.osdl.org/show_bug.cgi?id=7426 The basic summary is: Currently we register most of i386/x86_64 clocksources at module_init time. Then we enable clocksource selection at late_initcall time. This causes some problems for drivers that use gettimeofday for init calibration routines (specifically the es1968 driver in this case), where durring module_init, the only clocksource available is the low-res jiffies clocksource. This may cause slight calibration errors, due to the small sampling time used. It should be noted that drivers that require fine grained time may not function on architectures that do not have better then jiffies resolution timekeeping (there are a few). However, this does not discount the reasonable need for such fine-grained timekeeping at init time. Thus the solution here is to register clocksources earlier (ideally when the hardware is being initialized), and then we enable clocksource selection at fs_initcall (before device_initcall). This patch should probably get some testing time in -mm, since clocksource selection is one of the most important issues for correct timekeeping, and I've only been able to test this on a few of my own boxes.

Recent patch for raid6 reshape had a change missing that showed up in subsequent review. Many places in the raid5 code used "conf->raid_disks-1" to mean "number of data disks". With raid6 that had to be changed to "conf->raid_disk - conf->max_degraded" or similar. One place was missed. This bug means that if a raid6 reshape were aborted in the middle the recorded position would be wrong. On restart it would either fail (as the position wasn't on an appropriate boundary) or would leave a section of the array unreshaped, causing data corruption.

Use para_fill instead of directly setting the APIC ops to the result of the vmi_get_function call - this allows one to implement a VMI ROM without implementing APIC functions, just using the native APIC functions.

Basically, we should never assume that the ROM implements a specific set of functions, and always allow fallback to the native implementation. This is critical for future compatibility.

And with the clocksource code now firmly in place, we can get rid of code that fixes up the wallclock, since this is done in the common infrastructure.

The time_init_hook in paravirt-ops no longer functions in the correct manner after the integration of the hrtimers code. The problem is that now the call path for time initialization is: time_init : late_time_init = hpet_time_init; late_time_init -> hpet_time_init: setup_pit_timer (BAD) do_time_init --> (via paravirt.h) time_init_hook --> (via arch_hooks.h) time_init_hook (in SUBARCH/setup.c) If this isn't confusing enough, the paravirt case goes through an indirect function pointer in the paravirt-ops table. The problem is, by the time the paravirt hook is called, the pit timer is already enabled. But paravirt guests have their own timer, and don't want to use the PIT. Rather than intensify the struggle for power going on here, just make it all nice and simple and just unconditionally do all timer setup in the late_time_init hook. This also has the advantage of enabling timers in the same place in all code paths, so everyone has the same bugs and we don't have outliers who break other code because they turn on timer too early or too late. So the paravirt-ops time init function is now by default hpet_time_init, which is the time init function used for native hardware. Paravirt guests have the chance to override this when they setup the paravirt-ops table, and should need no change.

Not respecting udelay causes problems with any virtual hardware that is passed through to real hardware. This can be noticed by any device that interacts with the real world in real time - like AP startup, which takes real time. Or keyboard LEDs, which should blink in real-time. Or floppy drives, but only when passed through to a real floppy controller on OSes which can't sufficiently buffer the floppy commands to emulate a zero latency floppy. Or IDE drives, when connecting to a physical CDROM. This was mostly a hack to get the kernel to boot faster, but it introduced a number of misvirtualization bugs, and Alan and Pavel argued pretty strongly against it.

Provide a PT map hook for HIGHPTE kernels to designate where they are mapping page tables. This information is required so the physical address of PTE updates can be determined; otherwise, the mm layer would have to carry the physical address all the way to each PTE modification callsite, which is even more hideous that the macros required to provide the proper hooks. So lets not mess up arch neutral code to achieve this, but keep the horror in an #ifdef HIGHPTE in include/asm-i386/pgtable.h.
