latest -git triggers an irqtrace/lockdep warning of a leaked irqs-off condition: BUG: at kernel/fork.c:1033 copy_process() after some debugging it turns out that commit ca1b940c accidentally left interrupts disabled - which trickled down all the way to the first time we fork a kernel thread and triggered the warning. the fix is to re-enable interrupts in the 'else' branch of setup_boot_APIC_clock()'s pmtimers calibration path.

lockdep's data shouldn't be used when debug_locks == 0 because it's not updated after this, so it's more misleading than helpful. PS: probably lockdep's current-> fields should be reset after it turns debug_locks off: so, after printing a bug report, but before return from exported functions, but there are really a lot of these possibilities (e.g. after DEBUG_LOCKS_WARN_ON), so, something could be missed. (Of course direct use of this fields isn't recommended either.) Reported-by:

It causes extra moon icons blinking on x60, and breaks at least two other systems. During resume, we do not know that "reboot"/"shutdown" method was used, so we assume "plaform" and call BIOS, anyway... This is 2.6.21 material, and should fix 2 or 3 regressions from 2.6.20. Signed-off-by:

The local APIC timer stops to work in deeper C-States. This is handled by the ACPI code and a broadcast mechanism in the clockevents / tick managment code. Some systems do not expose the deeper C-States to the kernel, but switch into deeper C-States behind the kernels back. This delays the local apic timer interrupts for ever and makes the systems unusable. Add a command line option to disable the local apic timer and a dmi quirk for known broken systems. Andi sayeth: While not wrong by itself i think it is still better to use some heuristic -- like "has battery in ACPI" With the DMI table if the problem is more wide spread we will just continue extending it. But anyways should be ok now for .21 although I'm not really happy with it. Signed-off-by:

The PIT has no dedicated mode for shut down. The only way to disable PIT is to put it into one shot mode. AMD implementations of PIT on Geode (also observed on Cyrix) are confused by an "empty" transition from CLOCK_EVT_MODE_UNUSED to CLOCK_EVT_MODE_SHUTDOWN, which puts the PIT into one shot mode momentarily. I realized after staring helpless at the bug report http://bugzilla.kernel.org/show_bug.cgi?id=8027 for quite a while, that the only change, which might influence the bogomips calibration, is the above transition during the PIT initialization. Avoiding the unnecessary switch to oneshot and later to periodic mode fixes the weird bogomips value and also the resulting slowness. The fix is confirmed on OLPC and another Geode based box. Note: this is unrelated to the Dual Core problem discussed here: http://lkml.org/lkml/2007/3/17/48Signed-off-by:

When a file had a dos attribute of 0x1 (readonly - but dos attribute of archive was not set) - doing chmod 0777 or equivalent would try to set a dos attribute of 0 (which some servers ignore) rather than ATTR_NORMAL (0x20) which most servers accept. Does not affect servers which support the CIFS Unix Extensions. Acked-by:

The packet length checks in ipoib are broken: we add 4 bytes (IPoIB encapsulation header) when sending a packet, not 20 bytes (hardware address length) to each packet. Therefore, if connected mode is enabled so that the interface MTU is larger than the multicast MTU, IPoIB may end up trying to send too-long multicast packets. For example, multicast is broken if a message of size 2048 bytes is sent on an interface with UD MTU 2048, because 2048 is bigger than the real limit of 2044 but the code tests against the wrong limit of 2060.

There's a race between ipoib_mcast_leave() and ipoib_mcast_join_finish() where we can try to detach from a multicast group before we've attached to it. Fix this by reordering the code in ipoib_mcast_leave to free the multicast group first, which waits for the multicast callback thread (which calls ipoib_mcast_join_finish()) to complete before detaching from the group.

Currently NAT not only reroutes packets in the OUTPUT chain when the routing key changed, but also if only the non-routing part of the IPsec policy key changed. This breaks ping -I since it doesn't use SO_BINDTODEVICE but IP_PKTINFO cmsg to specify the output device, and this information is lost. Only do full rerouting if the routing key changed, and just do a new policy lookup with the old route if only the ports changed. Signed-off-by:

kexec invokes plpar_hcall hypervisor call in real mode. plpar_hcall refers to per cpu variables for accounting hypervisor statistics. These variables may not be in the RMO region, so accesses to them in real mode may result in a data storage exception. This fixes this problem by using a new plpar_hcall_raw function which does not update the hypervisor call statistics. Thanks to Anton for suggesting this idea. Signed-off-by:
