* hrtimers: simplify lockdep handlingOleg Nesterov2008-04-17
| | | | | | | | | | | | | | | | In order to avoid the false positive from lockdep, each per-cpu base->lock has the separate lock class and migrate_hrtimers() uses double_spin_lock(). This is overcomplicated: except for migrate_hrtimers() we never take 2 locks at once, and migrate_hrtimers() can use spin_lock_nested().

For this we add a new struct device pointer to the SSB device structure that will always point to the right device for DMAing.

However because netconsole has CON_PRINTBUFFER set, when it is registered it causes the printk buffer to be replayed to all consoles. When there is no netconsole configured this is a) pointless, and b) somewhat annoying for the user of the existing console. So instead we should only set CON_PRINTBUFFER if there is a netconsole configuration found on the command line. This retains the existing behaviour if a netconsole is setup by the user, and avoids spamming other consoles when we're only registering for the dynamic netconsole case.

Therefore sk_rmem_schedule() can fail but the out-of-order queue isn't pruned . This can lead to tcp deadlock state if the next two conditions are held: 1. There are a sequence hole between last received in order segment and segments enqueued to the out-of-order queue. 2. Size of all segments in the out-of-order queue is more than tcp_mem[2].

After this all qdisc_lookups give the same, and we get endless loop. (I don't know how this could hide for so long - it should trigger with every leaf class deleted if it's qdisc isn't empty.) After this fix qdisc_lookup() is omitted both for ingress and root parents, but looking for root is only wasting a little time here...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPI core now expects num_chipselect to be set correctly as due to added checks on the chip being selected before an transfer is allowed. This patch adds a num_cs field to the platform data which needs to be set correctly before adding the SPI platform device.

* | | vfs: fix possible deadlock in ext2, ext3, ext4 when using xattrsJan Kara2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mb_cache_entry_alloc() was allocating cache entries with GFP_KERNEL. But filesystems are calling this function while holding xattr_sem so possible recursion into the fs violates locking ordering of xattr_sem and transaction start / i_mutex for ext2-4. Change mb_cache_entry_alloc() so that filesystems can specify desired gfp mask and use GFP_NOFS from all of them.

* | | Documentation: correct overcommit caveat in hugetlbpage.txtNishanth Aravamudan2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As shown by Gurudas Pai recently, we can put hugepages into the surplus state (by echo 0 > /proc/sys/vm/nr_hugepages), even when /proc/sys/vm/nr_overcommit_hugepages is 0. This is actually correct, to allow the original goal (shrink the static pool to 0) to succeed (we are converting hugepages to surplus because they are in use). However, the documentation does not accurately reflect this case. Update it.
