2010-06-03epic100: Test __BIG_ENDIAN instead of (non-existent) CONFIG_BIG_ENDIANRoland Dreier1-3/+4
Probably no one has used this driver on big-endian systems, since it was setting up descriptor swapping if CONFIG_BIG_ENDIAN is set, which it never is, since that symbol is not mentioned anywhere else in the kernel source. Switch this test to a check for __BIG_ENDIAN so it has a chance at working. Signed-off-by: Roland Dreier <[email protected]> Acked-by: Jeff Garzik <[email protected]> Signed-off-by: David S.

2010-06-03sfc: Get port number from CS_PORT_NUM, not PCI function numberBen Hutchings2-1/+7
A single shared memory region used to communicate with firmware is mapped into both PCI PFs of the SFC9020 and SFL9021. Drivers must be able to identify which port they are addressing in order to use the correct sub-region. Currently we use the PCI function number, but the PCI address may be virtualised. Use the CS_PORT_NUM register field defined for just this purpose. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang75-141/+4
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-06-03i2c: Check for address validity on client registrationJean Delvare1-7/+26
Do basic address validity checks when a client is being registered. We already had checks in place for devices which are being detected, but not for devices which are simply instantiated. This is a very basic check. We don't want to do strict checking here because some devices are known to infringe the I2C address constraints (e.g. IR receivers at 7-bit address 0x7a while this value is supposedly reserved for 10-bit addresses.) So we assume the caller knows what it is doing. Signed-off-by: Jean Delvare <[email protected]> Cc: Matthieu Castet <[email protected]>

2010-06-03xen: avoid allocation causing potential swap activity on the resume pathIan Campbell1-1/+1
Since the device we are resuming could be the device containing the swap device we should ensure that the allocation cannot cause IO. On resume, this path is triggered when the running system tries to continue using its devices. If it cannot then the resume will fail; to try to avoid this we let it dip into the emergency pools. The majority of these changes were made when linux-2.6.18-xen.hg changeset e8b49cfbdac0 was ported upstream in a144ff09bc52ef3f3684ed23eadc9c7c0e57b3aa but somehow this hunk was dropped.

2010-06-03xen: ensure timer tick is resumed even on CPU driving the resumeIan Campbell1-2/+2
The core suspend/resume code is run from stop_machine on CPU0 but parts of the suspend/resume machinery (including xen_arch_resume) are run on whichever CPU happened to schedule the xenwatch kernel thread. As part of the non-core resume code xen_arch_resume is called in order to restart the timer tick on non-boot processors. The boot processor itself is taken care of by core timekeeping code. xen_arch_resume uses smp_call_function which does not call the given function on the current processor. This means that we can end up with one CPU not receiving timer ticks if the xenwatch thread happened to be scheduled on CPU > 0. Use on_each_cpu instead of smp_call_function to ensure the timer tick is resumed everywhere.

2010-06-03xfs: skip writeback from reclaim contextChristoph Hellwig1-0/+15
Allowing writeback from reclaim context causes massive problems with stack overflows as we can call into the writeback code which tends to be a heavy stack user both in the generic code and XFS from random contexts that perform memory allocations. Follow the example of btrfs (and in slightly different form ext4) and refuse to write out data from reclaim context. This issue should really be handled by the VM so that we can tune better for this case, but until we get it sorted out there we have to hack around this in each filesystem with a complex writeback path.

2010-06-03xfs: fix race in inode cluster freeing failing to stale inodesDave Chinner1-80/+62
When an inode cluster is freed, it needs to mark all inodes in memory as XFS_ISTALE before marking the buffer as stale. This is eeded because the inodes have a different life cycle to the buffer, and once the buffer is torn down during transaction completion, we must ensure none of the inodes get written back (which is what XFS_ISTALE does). Unfortunately, xfs_ifree_cluster() has some bugs that lead to inodes not being marked with XFS_ISTALE. This shows up when xfs_iflush() is called on these inodes either during inode reclaim or tail pushing on the AIL. The buffer is read back, but no longer contains inodes and so triggers assert failures and shutdowns. This was reproducable with at run.dbench10 invocation from xfstests. There are two main causes of xfs_ifree_cluster() failing. The first is simple - it checks in-memory inodes it finds in the per-ag icache to see if they are clean without holding the flush lock. if they are clean it skips them completely. However, If an inode is flushed delwri, it will appear clean, but is not guaranteed to be written back until the flush lock has been dropped. Hence we may have raced on the clean check and the inode may actually be dirty. Hence always mark inodes found in memory stale before we check properly if they are clean. The second is more complex, and makes the first problem easier to hit. Basically the in-memory inode scan is done with full knowledge it can be racing with inode flushing and AIl tail pushing, which means that inodes that it can't get the flush lock on might not be attached to the buffer after then in-memory inode scan due to IO completion occurring. This is actually documented in the code as "needs better interlocking". i.e. this is a zero-day bug. Effectively, the in-memory scan must be done while the inode buffer is locked and Io cannot be issued on it while we do the in-memory inode scan. This ensures that inodes we couldn't get the flush lock on are guaranteed to be attached to the cluster buffer, so we can then catch all in-memory inodes and mark them stale. Now that the inode cluster buffer is locked before the in-memory scan is done, there is no need for the two-phase update of the in-memory inodes, so simplify the code into two loops and remove the allocation of the temporary buffer used to hold locked inodes across the phases.
