This is often because arch_register_cpu lacks a __devinit annotation or the annotation of register_cpu is wrong. The only external user of arch_register_cpu in the tree is in drivers/acpi/processor_core.c where it is guarded by ACPI_HOTPLUG_CPU (which depends on HOTPLUG_CPU).

* | futex: Add bitset conditional wait/wakeup functionalityThomas Gleixner2008-02-012-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To allow the implementation of optimized rw-locks in user space, glibc needs a possibility to select waiters for wakeup depending on a bitset mask. This requires two new futex OPs: FUTEX_WAIT_BITS and FUTEX_WAKE_BITS These OPs are basically the same as FUTEX_WAIT and FUTEX_WAKE plus an additional argument - a bitset. Further the FUTEX_WAIT_BITS OP is expecting an absolute timeout value instead of the relative one, which is used for the FUTEX_WAIT OP. FUTEX_WAIT_BITS calls into the kernel with a bitset. The bitset is stored in the futex_q structure, which is used to enqueue the waiter into the hashed futex waitqueue. FUTEX_WAKE_BITS also calls into the kernel with a bitset. The wakeup function logically ANDs the bitset with the bitset stored in each waiters futex_q structure. If the result is zero (i.e. none of the set bits in the bitsets is matching), then the waiter is not woken up. If the result is not zero (i.e. one of the set bits in the bitsets is matching), then the waiter is woken. The bitset provided by the caller must be non zero. In case the provided bitset is zero the kernel returns EINVAL. Internaly the new OPs are only extensions to the existing FUTEX_WAIT and FUTEX_WAKE functions. The existing OPs hand a bitset with all bits set into the futex_wait() and futex_wake() functions. Signed-off-by: Thomas Gleixner <tgxl@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* | x86: replace LOCK_PREFIX in futex.hThomas Gleixner2008-02-011-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The exception fixup for the futex macros __futex_atomic_op1/2 and futex_atomic_cmpxchg_inatomic() is missing an entry when the lock prefix is replaced by a NOP via SMP alternatives. Chuck Ebert tracked this down from the information provided in: https://bugzilla.redhat.com/show_bug.cgi?id=429412 A possible solution would be to add another fixup after the LOCK_PREFIX, so both the LOCK and NOP case have their own entry in the exception table, but it's not really worth the trouble. Simply replace LOCK_PREFIX with lock and keep those untouched by SMP alternatives. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | To allow better diagnosis of tick-sched related, especially NOHZ related problems, we need to know when the last wakeup via an irq happened and when the CPU left the idle state.

| * | [NETNS]: Lookup in FIB semantic hashes taking into account the namespace.Denis V. Lunev2008-02-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The namespace is not available in the fib_sync_down_addr, add it as a parameter. Looking up a device by the pointer to it is OK. Looking up using a result from fib_trie/fib_hash table lookup is also safe. No need to fix that at all. So, just fix lookup by address and insertion to the hash table path. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | [NETNS]: Add a namespace mark to fib_info.Denis V. Lunev2008-02-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is required to make fib_info lookups namespace aware. In the other case initial namespace devices are marked as dead in the local routing table during other namespace stop. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S.

| * | [IPV4]: fib_sync_down rework.Denis V. Lunev2008-02-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fib_sync_down can be called with an address and with a device. In reality it is called either with address OR with a device. The codepath inside is completely different, so lets separate it into two calls for these two cases. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S.

Some examples: - Classic SFQ hash: tc filter add ... flow hash \ keys src,dst,proto,proto-src,proto-dst divisor 1024 - Classic SFQ hash, but using information from conntrack to work properly in combination with NAT: tc filter add ... flow hash \ keys nfct-src,nfct-dst,proto,nfct-proto-src,nfct-proto-dst divisor 1024 - Map destination IPs of 192.168.0.0/24 to classids 1-257: tc filter add ... flow map \ key dst addend -192.168.0.0 divisor 256 - alternatively: tc filter add ... flow map \ key dst and 0xff - similar, but reverse ordered: tc filter add ... flow map \ key dst and 0xff xor 0xff Perturbation is currently not supported because we can't reliable kill the timer on destruction.

| * | [IPV4] route cache: Introduce rt_genid for smooth cache invalidationEric Dumazet2008-02-012-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current ip route cache implementation is not suited to large caches. We can consume a lot of CPU when cache must be invalidated, since we currently need to evict all cache entries, and this eviction is sometimes asynchronous. min_delay & max_delay can somewhat control this asynchronism behavior, but whole thing is a kludge, regularly triggering infamous soft lockup messages. When entries are still in use, this also consumes a lot of ram, filling dst_garbage.list. A better scheme is to use a generation identifier on each entry, so that cache invalidation can be performed by changing the table identifier, without having to scan all entries. No more delayed flushing, no more stalling when secret_interval expires. Invalidated entries will then be freed at GC time (controled by ip_rt_gc_timeout or stress), or when an invalidated entry is found in a chain when an insert is done. Thus we keep a normal equilibrium. This patch : - renames rt_hash_rnd to rt_genid (and makes it an atomic_t) - Adds a new rt_genid field to 'struct rtable' (filling a hole on 64bit) - Checks entry->rt_genid at appropriate places :
| * | [VLAN]: set_rx_mode support for unicast address listChris Leech2008-02-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reuse the existing logic for multicast list synchronization for the unicast address list. The core of dev_mc_sync/unsync are split out as __dev_addr_sync/unsync and moved from dev_mcast.c to dev.c. These are then used to implement dev_unicast_sync/unsync as well. I'm working on cleaning up Intel's FCoE stack, which generates new MAC addresses from the fibre channel device id assigned by the fabric as per the current draft specification in T11. When using such a protocol in a VLAN environment it would be nice to not always be forced into promiscuous mode, assuming the underlying Ethernet driver supports multiple unicast addresses as well.

| * | [IPV4] fib_trie: rescan if key is lost during dumpStephen Hemminger2008-02-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally during a dump the key of the last dumped entry is used for continuation, but since lock is dropped it might be lost. In that case fallback to the old counter based N^2 behaviour. This means the dump will end up skipping some routes which matches what FIB_HASH does.
