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.

2006-05-09[TG3]: Fix possible NULL deref in tg3_run_loopback().Jesper Juhl
tg3_run_loopback doesn't check that dev_alloc_skb() returns anything useful. Even if dev_alloc_skb() fails to return an skb to us we'll happily go on and assume it did, so we risk dereferencing a NULL pointer. Much better to fail gracefully by returning -ENOMEM than crashing here. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-05-09[NET] linkwatch: Handle jiffies wrap-aroundHerbert Xu
The test used in the linkwatch does not handle wrap-arounds correctly. Since the intention of the code is to eliminate bursts of messages we can afford to delay things up to a second. Using that fact we can easily handle wrap-arounds by making sure that we don't delay things by more than one second. This is based on diagnosis and a patch by Stefan Rompf.

2006-05-08sky2: edge triggered workaround enhancementStephen Hemminger
Need to make the edge-triggered workaround timer faster to get marginally better peformance. The test_and_set_bit in schedule_prep() acts as a barrier already. Make it a module parameter so that laptops who are concerned about power can set it to 0; and user's stuck with broken BIOS's can turn the driver into pure polling.

2006-05-08sky2: status irq hang fixStephen Hemminger

2006-05-08[PATCH] x86_64: Move ondemand timer into own work queueAndi Kleen
Taking the cpu hotplug semaphore in a normal events workqueue is unsafe because other tasks can wait for any workqueues with it hold. This results in a deadlock. Move the DBS timer into its own work queue which is not affected by other work queue flushes to avoid this. Has been acked by Venkatesh.

2006-05-08[PATCH] x86_64: Avoid EBDA area in early boot allocatorAndi Kleen
Based on analysis&patch from Robert Hentosch Observed on a Dell PE6850 with 16GB The problem occurs very early on, when the kernel allocates space for the temporary memory map called bootmap. The bootmap overlaps the EBDA region. EBDA region is not historically reserved in the e820 mapping. When the bootmap is freed it marks the EBDA region as usable. If you notice in setup.c there is already code to work around the EBDA in reserve_ebda_region(), this check however occurs after the bootmap is allocated and doesn't prevent the bootmap from using this range. AK: I redid the original patch. Thanks also to Jan Beulich for spotting some mistakes.

2006-05-08[PATCH] x86_64: add nmi_exit to die_nmiCorey Minyard
Playing with NMI watchdog on x86_64, I discovered that it didn't do what I expected. It always panic-ed, even when it didn't happen from interrupt context. This patch solves that problem for me. Also, in this case, do_exit() will be called with interrupts disabled, I believe. Would it be wise to also call local_irq_enable() after nmi_exit()? [Yes I added it -AK] Currently, on x86_64, any NMI watchdog timeout will cause a panic because the irq count will always be set to be in an interrupt when do_exit() is called from die_nmi(). If we add nmi_exit() to the die_nmi() call (since the nmi will never exit "normally") it seems to solve this problem. The following small program can be used to trigger the NMI watchdog to reproduce this: main () { iopl(3); for (;;) asm("cli"); } Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-05-08[PATCH] x86_64: fix die_lock nestingCorey Minyard
I noticed this when poking around in this area. The oops_begin() function in x86_64 would only conditionally claim the die_lock if the call is nested, but oops_end() would always release the spinlock. This patch adds a nest count for the die lock so that the release of the lock is only done on the final oops_end().

2006-05-08[PATCH] x86_64: avoid IRQ0 ioapic pin collisionKimball Murray
The patch addresses a problem with ACPI SCI interrupt entry, which gets re-used, and the IRQ is assigned to another unrelated device. The patch corrects the code such that SCI IRQ is skipped and duplicate entry is avoided. Second issue came up with VIA chipset, the problem was caused by original patch assigning IRQs starting 16 and up. The VIA chipset uses 4-bit IRQ register for internal interrupt routing, and therefore cannot handle IRQ numbers assigned to its devices. The patch corrects this problem by allowing PCI IRQs below 16.
