2009-06-11tty: Clean up the ACM driver to CodingStyleAlan Cox
Or at least most of it. There are further clean ups possible and there are are also thing checkpatch moans about that would be silly to "fix".

2009-06-11tty: cyclades, fix nports handlingJiri Slaby
Set up ports right after FW load so that we won't allocate maximal (64) ports when we use few. Also remove reading of nports in irq context, since we know it from initialisation now. This also fixes a tty ports unregistration on some fail paths and for Ze which registered 64 and unregistered real port count.

2009-06-11tty: synclink_gt add receive pio modePaul Fulghum
Add receive programmed IO mode to reduce receive latency when using low data rates. The receive FIFO trigger level of 128 bytes used in DMA mode creates excessive latency when operating at low data rates. PIO mode is selected when user application requests data in blocks of less than 128 bytes.

2009-06-11tty: Bring the usb tty port structure into more useAlan Cox
This allows us to clean stuff up, but is probably also going to cause some app breakage with buggy apps as we now implement proper POSIX behaviour for USB ports matching all the other ports.

2009-06-09char: mxser, fix ISA board lookupPeter Botha
There's a bug in the mxser kernel module that still appears in the 2.6.29.4 kernel. mxser_get_ISA_conf takes a ioaddress as its first argument, by passing the not of the ioaddr, you're effectively passing 0 which means it won't be able to talk to an ISA card. I have tested this, and removing the ! fixes the problem.

2009-06-09jbd: fix race in buffer processing in commit codeJan Kara
In commit code, we scan buffers attached to a transaction. During this scan, we sometimes have to drop j_list_lock and then we recheck whether the journal buffer head didn't get freed by journal_try_to_free_buffers(). But checking for buffer_jbd(bh) isn't enough because a new journal head could get attached to our buffer head. So add a check whether the journal head remained the same and whether it's still at the same transaction and list. This is a nasty bug and can cause problems like memory corruption (use after free) or trigger various assertions in JBD code (observed).

2009-06-09autofs4: remove hashed check in validate_wait()Ian Kent
The recent ->lookup() deadlock correction required the directory inode mutex to be dropped while waiting for expire completion. We were concerned about side effects from this change and one has been identified. I saw several error messages. They cause autofs to become quite confused and don't really point to the actual problem. Things like: handle_packet_missing_direct:1376: can't find map entry for (43,1827932) which is usually totally fatal (although in this case it wouldn't be except that I treat is as such because it normally is). do_mount_direct: direct trigger not valid or already mounted /test/nested/g3c/s1/ss1 which is recoverable, however if this problem is at play it can cause autofs to become quite confused as to the dependencies in the mount tree because mount triggers end up mounted multiple times. It's hard to accurately check for this over mounting case and automount shouldn't need to if the kernel module is doing its job. There was one other message, similar in consequence of this last one but I can't locate a log example just now. When checking if a mount has already completed prior to adding a new mount request to the wait queue we check if the dentry is hashed and, if so, if it is a mount point. But, if a mount successfully completed while we slept on the wait queue mutex the dentry must exist for the mount to have completed so the test is not really needed. Mounts can also be done on top of a global root dentry, so for the above case, where a mount request completes and the wait queue entry has already been removed, the hashed test returning false can cause an incorrect callback to the daemon. Also, d_mountpoint() is not sufficient to check if a mount has completed for the multi-mount case when we don't have a real mount at the base of the tree.

2009-06-09r8169: fix crash when large packets are receivedEric Dumazet
Michael Tokarev reported receiving a large packet could crash a machine with RTL8169 NIC. ( original thread at http://lkml.org/lkml/2009/6/8/192 ) Problem is this driver tells that NIC frames up to 16383 bytes can be received but provides skb to rx ring allocated with smaller sizes (1536 bytes in case standard 1500 bytes MTU is used) When a frame larger than what was allocated by driver is received, dma transfert can occurs past the end of buffer and corrupt kernel memory. Fix is to tell to NIC what is the maximum size a frame can be. This bug is very old, (before git introduction, linux-2.6.10), and should be backported to stable versions.

2009-06-09md/raid5: fix bug in reshape code when chunk_size decreases.NeilBrown
Now that we support changing the chunksize, we calculate "reshape_sectors" to be the max of number of sectors in old and new chunk size. However there is one please where we still use 'chunksize' rather than 'reshape_sectors'. This causes a reshape that reduces the size of chunks to freeze. Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-09md/raid5 - avoid deadlocks in get_active_stripe during reshapeNeilBrown
md has functionality to 'quiesce' and array so that all pending IO completed and no new IO starts. This is used to achieve a stable state before making internal changes. Currently this quiescing applies equally to normal IO, resync IO, and reshape IO. However there is a problem with applying it to reshape IO. Reshape can have multiple 'stripe_heads' that must be active together. If the quiesce come between allocating the first and the last of such a collection, then we deadlock, as the last will not be allocated until the quiesce is lifted, the quiesce will not be lifted until the first (which has been allocated) gets used, and that first cannot be used until the last is allocated. It is not necessary to inhibit reshape IO when a quiesce is requested. Those places in the code that require a full quiesce will ensure the reshape thread is not running at all. So allow reshape requests to get access to new stripe_heads without being blocked by a 'quiesce'. This only affects in-place reshapes (i.e. where the array does not grow or shrink) and these are only newly supported. So this patch is not needed in earlier kernels.

2009-06-09md/raid5: use conf->raid_disks in preference to mddev->raid_diskNeilBrown
mddev->raid_disks can be changed and any time by a request from user-space. It is a suggestion as to what number of raid_disks is desired. conf->raid_disks can only be changed by the raid5 module with suitable locks in place. It is a statement as to the current number of raid_disks. There are two places where the latter should be used, but the former is used. This can lead to a crash when reshaping an array. This patch changes to mddev-> to conf-> Signed-off-by: NeilBrown <neilb@suse.de>
2009-06-08async: Fix lack of boot-time console due to insufficient synchronizationLinus Torvalds
Our async work synchronization was broken by "async: make sure independent async domains can't accidentally entangle" (commit d5a877e8dd409d8c702986d06485c374b705d340), because it would report the wrong lowest active async ID when there was both running and pending async work. This caused things like no being able to read the root filesystem, resulting in missing console devices and inability to run 'init', causing a boot-time panic. This fixes it by properly returning the lowest pending async ID: if there is any running async work, that will have a lower ID than any pending work, and we should _not_ look at the pending work list. There were alternative patches from Jaswinder and James, but this one also cleans up the code by removing the pointless 'ret' variable and the unnecesary testing for an empty list around 'for_each_entry()' (if the list is empty, the for_each_entry() thing just won't execute).

2009-06-08MIPS: Outline udelay and fix a few issues.Ralf Baechle
Outlining fixes the issue were on certain CPUs such as the R10000 family the delay loop would need an extra cycle if it overlaps a cacheline boundary. The rewrite also fixes build errors with GCC 4.4 which was changed in way incompatible with the kernel's inline assembly. Relying on pure C for computation of the delay value removes the need for explicit. The price we pay is a slight slowdown of the computation - to be fixed on another day.

2009-06-08KVM: Explicity initialize cpus_hardware_enabledAvi Kivity
Under CONFIG_MAXSMP, cpus_hardware_enabled is allocated from the heap and not statically initialized. This causes a crash on reboot when kvm thinks vmx is enabled on random nonexistent cpus and accesses nonexistent percpu lists. Fix by explicitly clearing the variable.

2009-06-07pdc202xx_old: fix resetproc() methodSergei Shtylyov
pdc202xx_reset() calls pdc202xx_reset_host() twice, for both channels, while that function actually twiddles the single, shared software reset bit -- the net effect is a duplicated reset and horrendous 4 second delay happening not only on a channel reset but also when dma_lost_irq() and dma_clear() methods are called. Fold pdc202xx_reset_host() into pdc202xx_reset(), fix printk(), and move it before the actual reset...
