2009-08-05intel-iommu: Correct sglist size calculation.Fenghua Yu
In domain_sg_mapping(), use aligned_nrpages() instead of hand-coded rounding code for calculating the size of each sg elem. This means that on IA64 we correctly round up to the MM page size, not just to the VT-d page size. Also remove the incorrect mm_to_dma_pfn() when intel_map_sg() calls domain_sg_mapping() -- the 'size' variable is in VT-d pages already.

2009-08-04tty-ldisc: be more careful in 'put_ldisc' lockingLinus Torvalds
Use 'atomic_dec_and_lock()' to make sure that we always hold the tty_ldisc_lock when the ldisc count goes to zero. That way we can never race against 'tty_ldisc_try()' increasing the count again.

2009-08-04tty-ldisc: turn ldisc user count into a proper refcountLinus Torvalds
By using the user count for the actual lifetime rules, we can get rid of the silly "wait_for_idle" logic, because any busy ldisc will automatically stay around until the last user releases it. This avoids a host of odd issues, and simplifies the code. So now, when the last ldisc reference is dropped, we just release the ldisc operations struct reference, and free the ldisc. It looks obvious enough, and it does work for me, but the counting _could_ be off. It probably isn't (bad counting in the new version would generally imply that the old code did something really bad, like free an ldisc with a non-zero count), but it does need some testing, and preferably somebody looking at it. With this change, both 'tty_ldisc_put()' and 'tty_ldisc_deref()' are just aliases for the new ref-counting 'put_ldisc()'. Both of them decrement the ldisc user count and free it if it goes down to zero. They're identical functions, in other words. But the reason they still exist as sepate functions is that one of them was exported (tty_ldisc_deref) and had a stupid name (so I don't want to use it as the main name), and the other one was used in multiple places (and I didn't want to make the patch larger just to rename the users). In addition to the refcounting, I did do some minimal cleanup. For example, now "tty_ldisc_try()" actually returns the ldisc it got under the lock, rather than returning true/false and then the caller would look up the ldisc again (now without the protection of the lock). That said, there's tons of dubious use of 'tty->ldisc' without obviously proper locking or refcounting left. I expressly did _not_ want to try to fix it all, keeping the patch minimal. There may or may not be bugs in that kind of code, but they wouldn't be _new_ bugs. That said, even if the bugs aren't new, the timing and lifetime will change. For example, some silly code may depend on the 'tty->ldisc' pointer not changing because they hold a refcount on the 'ldisc'. And that's no longer true - if you hold a ref on the ldisc, the 'ldisc' itself is safe, but tty->ldisc may change. So the proper locking (remains) to hold tty->ldisc_mutex if you expect tty->ldisc to be stable. That's not really a _new_ rule, but it's an example of something that the old code might have unintentionally depended on and hidden bugs. Whatever. The patch _looks_ sensible to me. The only users of ldisc->users are: - get_ldisc() - atomically increment the count - put_ldisc() - atomically decrements the count and releases if zero - tty_ldisc_try_get() - creates the ldisc, and sets the count to 1. The ldisc should then either be released, or be attached to a tty.

2009-08-04tty-ldisc: make refcount be atomic_t 'users' countLinus Torvalds
This is pure preparation of changing the ldisc reference counting to be a true refcount that defines the lifetime of the ldisc. But this is a purely syntactic change for now to make the next steps easier. This patch should make no semantic changes at all. But I wanted to make the ldisc refcount be an atomic (I will be touching it without locks soon enough), and I wanted to rename it so that there isn't quite as much confusion between 'ldo->refcount' (ldisk operations refcount) and 'ld->refcount' (ldisc refcount itself) in the same file. So it's now an atomic 'ld->users' count. It still starts at zero, despite having a reference from 'tty->ldisc', but that will change once we turn it into a _real_ refcount.

Commit ee88415caf736b89500f16e0a545614541a45005 introduced this regression when it removed enable bit in cpu_dbs_info_s. That added a possibility of dbs_cpufreq_notifier getting called for a CPU that is not yet managed by conservative governor. That will happen as the transition notifier is set as soon as one CPU switches to conservative governor and other CPUs can get a NULL pointer dereference without the enable bit check.

2009-08-04mfd: twl4030 irq fixesRussell King
The TWL4030 IRQ handler has a bug which leads to spinlock lock-up. It is calling the 'unmask' function in a process context. :The mask/unmask/ack functions are only designed to be called from the IRQ handler code, or the proper API interfaces found in linux/interrupt.h. Also there is no need to have IRQ chaining mechanism. The right way to handle this is to claim the parent interrupt as a standard interrupt and arrange for handle_twl4030_pih to take care of the rest of the devices.

2009-08-03cfg80211: fix regression on beacon world roaming featureLuis R. Rodriguez
A regression was added through patch a4ed90d6: "cfg80211: respect API on orig_flags on channel for beacon hint" We did indeed respect _orig flags but the intention was not clearly stated in the commit log. This patch fixes firmware issues picked up by iwlwifi when we lift passive scan of beaconing restrictions on channels its EEPROM has been configured to always enable. By doing so though we also disallowed beacon hints on devices registering their wiphy with custom world regulatory domains enabled, this happens to be currently ath5k, ath9k and ar9170. The passive scan and beacon restrictions on those devices would never be lifted even if we did find a beacon and the hardware did support such enhancements when world roaming. Since Johannes indicates iwlwifi firmware cannot be changed to allow beacon hinting we set up a flag now to specifically allow drivers to disable beacon hints for devices which cannot use them. We enable the flag on iwlwifi to disable beacon hints and by default enable it for all other drivers. It should be noted beacon hints lift passive scan flags and beacon restrictions when we receive a beacon from an AP on any 5 GHz non-DFS channels, and channels 12-14 on the 2.4 GHz band. We don't bother with channels 1-11 as those channels are allowed world wide. This should fix world roaming for ath5k, ath9k and ar9170, thereby improving scan time when we receive the first beacon from any AP, and also enabling beaconing operation (AP/IBSS/Mesh) on cards which would otherwise not be allowed to do so. Drivers not using custom regulatory stuff (wiphy_apply_custom_regulatory()) were not affected by this as the orig_flags for the channels would have been cleared upon wiphy registration. I tested this with a world roaming ath5k card. Cc: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: Luis R.

2009-08-03ixgbe: Patch to modify 82598 PCIe completion timeout valuesMallikarjuna R Chilakala
The default completion timeout values for 82598 should be in the range of 50us to 50ms, however the hardware default for these parts is 500us to 1ms which is less than the 10ms recommended by the pcie spec. To address this we need to increase the value to either 10ms to 250ms for capability version 1 configuration, or 16ms to 55ms for version 2.

2009-08-03md: Use revalidate_disk to effect changes in size of device.NeilBrown
As revalidate_disk calls check_disk_size_change, it will cause any capacity change of a gendisk to be propagated to the blockdev inode. So use that instead of mucking about with locks and i_size_write. Also add a call to revalidate_disk in do_md_run and a few other places where the gendisk capacity is changed.

2009-08-03md: allow raid5_quiesce to work properly when reshape is happening.NeilBrown
The ->quiesce method is not supposed to stop resync/recovery/reshape, just normal IO. But in raid5 we don't have a way to know which stripes are being used for normal IO and which for resync etc, so we need to wait for all stripes to be idle to be sure that all writes have completed. However reshape keeps at least some stripe busy for an extended period of time, so a call to raid5_quiesce can block for several seconds needlessly. So arrange for reshape etc to pause briefly while raid5_quiesce is trying to quiesce the array so that the active_stripes count can drop to zero. Signed-off-by: NeilBrown <neilb@suse.de>
2009-08-03md/raid5: set reshape_position correctly when reshape starts.NeilBrown
As the internal reshape_progress counter is the main driver for reshape, the fact that reshape_position sometimes starts with the wrong value has minimal effect. It is visible in sysfs and that is all. Signed-off-by: NeilBrown <neilb@suse.de>
2009-08-03md: Handle growth of v1.x metadata correctly.NeilBrown
The v1.x metadata does not have a fixed size and can grow when devices are added. If it grows enough to require an extra sector of storage, we need to update the 'sb_size' to match. Without this, md can write out an incomplete superblock with a bad checksum, which will be rejected when trying to re-assemble the array.

2009-08-03md: avoid array overflow with bad v1.x metadataNeilBrown
We trust the 'desc_nr' field in v1.x metadata enough to use it as an index in an array. This isn't really safe. So range-check the value first. Signed-off-by: NeilBrown <neilb@suse.de>
2009-08-03md: when a level change reduces the number of devices, remove the excess.NeilBrown
When an array is changed from RAID6 to RAID5, fewer drives are needed. So any device that is made superfluous by the level conversion must be marked as not-active. For the RAID6->RAID5 conversion, this will be a drive which only has 'Q' blocks on it. Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>
2009-08-03md: Push down data integrity code to personalities.Andre Noll
This patch replaces md_integrity_check() by two new public functions: md_integrity_register() and md_integrity_add_rdev() which are both personality-independent. md_integrity_register() is called from the ->run and ->hot_remove methods of all personalities that support data integrity. The function iterates over the component devices of the array and determines if all active devices are integrity capable and if their profiles match. If this is the case, the common profile is registered for the mddev via blk_integrity_register(). The second new function, md_integrity_add_rdev() is called from the ->hot_add_disk methods, i.e. whenever a new device is being added to a raid array. If the new device does not support data integrity, or has a profile different from the one already registered, data integrity for the mddev is disabled. For raid0 and linear, only the call to md_integrity_register() from the ->run method is necessary. Signed-off-by: Andre Noll <maan@systemlinux.org> Signed-off-by: NeilBrown <neilb@suse.de>
