2007-03-29[IFB]: Fix crash on input device removalPatrick McHardy
The input_device pointer is not refcounted, which means the device may disappear while packets are queued, causing a crash when ifb passes packets with a stale skb->dev pointer to netif_rx(). Fix by storing the interface index instead and do a lookup where neccessary. Signed-off-by: Patrick McHardy <kaber@trash.net> Acked-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S.

2007-03-28[BNX2]: Fix link interrupt problem.Michael Chan
bnx2_has_work()'s logic is flawed and can cause the driver to miss a link event. The fix is to compare the status block's attn_bits and attn_bits_ack to determine if there is a link event.

2007-03-28[PATCH] MSI-X: fix resume crashEric W. Biederman
So I think the right solution is to simply make pci_enable_device just flip enable bits and move the rest of the work someplace else. However a thorough cleanup is a little extreme for this point in the release cycle, so I think a quick hack that makes the code not stomp the irq when msi irq's are enabled should be the first fix. Then we can later make the code not change the irqs at all. Signed-off-by: Eric W.

hrtimer_start() incorrectly set the 'reprogram' flag to enqueue_hrtimer(), which should only be 1 if the hrtimer is queued to the current CPU. Doing otherwise could result in a reprogramming of the current CPU's clockevents device, with a timer that is not queued to it - resulting in a bogus next expiry value.

2007-03-28mv643xx_eth: Fix use of uninitialized port_num fieldGabriel Paubert
In this driver, the default ethernet address is first set by by calling eth_port_uc_addr_get() which reads the relevant registers of the corresponding port as initially set by firmware. However that function used the port_num field accessed through the private area of net_dev before it was set. The result was that one board I have ended up with the unicast address set to 00:00:00:00:00:00 (only port 1 is connected on this board). The problem appeared after commit 84dd619e4dc3b0b1c40dafd98c90fd950bce7bc5. This patch fixes the bug by setting mp->port_num prior to calling eth_port_uc_get_addr().

2007-03-27[PATCH] Revert "swsusp: disable nonboot CPUs before entering platform suspend"Rafael J. Wysocki
This reverts commit 94985134b7b46848267ed6b734320db01c974e72 and insteads removes the WARN_ON() that caused that commit in the first place. The problem is that we call disable_nonboot_cpus() in swsusp before powering down the system in order to avoid triggering the WARN_ON() in arch/x86_64/kernel/acpi/sleep.c:init_low_mapping() and this doesn't work well on Thomas' system. So instead, remove the WARN_ON() in arch/x86_64/kernel/acpi/sleep.c: init_low_mapping(), which triggers every time during the suspend to disk in the platform mode, as the potential problem it is related to doesn't seem to occur in practice. [ I think we might want to disallow the case of multiple users of that mm, or something. Normally, playing with the current process page tables on the current CPU should be fine as long as we don't have other threads using those tables at the same time..
