* [PATCH] Remove MODULE_PARMRusty Russell2006-03-25
| | | | | | | | | | MODULE_PARM was actually breaking: recent gcc version optimize them out as unused. It's time to replace the last users, which are generally in the most unloved drivers anyway.

* [PATCH] hysdn: remove custom typesAndrew Morton2006-03-25
| | | | | | | | | | | | | | | hysdn defines its own types: ulong, uint, uchar and word. Problem is, the module_param macros rely upon some of those identifiers having special meanings too. The net effect is that module_param() and friends cannot be used in ISDN because of this namespace clash. So remove the hysdn-private defines and open-code them all.

* [PATCH] Introduce FMODE_EXEC file flagOleg Drokin2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | Introduce FMODE_EXEC file flag, to indicate that file is being opened for execution. This is useful for distributed filesystems to maintain consistent behavior for returning ETXTBUSY when opening for write and execution happens on different nodes. akpm: Needed by Lustre at present. I assume their objective to to work towards being able to install Lustre on an unmodified distro kernel, which seems sane. It should have zero runtime cost.

* [PATCH] Missed error checking for intent's filp in open_namei().Oleg Drokin2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems there is error check missing in open_namei for errors returned through intent.open.file (from lookup_instantiate_filp). If there is plain open performed, then such a check done inside __path_lookup_intent_open called from path_lookup_open(), but when the open is performed with O_CREAT flag set, then __path_lookup_intent_open is only called with LOOKUP_PARENT set where no file opening can occur yet. Later on lookup_hash is called where exact opening might take place and intent.open.file may be filled. If it is filled with error value of some sort, then we get kernel attempting to dereference this error value as address (and corresponding oops) in nameidata_to_filp() called from filp_open(). While this is relatively simple to workaround in ->lookup() method by just checking lookup_instantiate_filp() return value and returning error as needed, this is not so easy in ->d_revalidate(), where we can only return "yes, dentry is valid" or "no, dentry is invalid, perform full lookup again", and just returning 0 on error would cause extra lookup (with potential extra costly RPCs). So in short, I believe that there should be no difference in error handling for opening a file and creating a file in open_namei() and propose this simple patch as a solution.

Originally bigsmp was added just to handle >8 cpus, but now with hotplug cpu support we need to use bigsmp mode (why? see below), that cause the above error message even if there were less than 8 cpus in the system. The message is bogus, but we are cannot use logical flat mode due to issues with broadcast IPI can confuse a CPU just comming up. We use flat physical mode just like x86_64 case.

* [PATCH] slab: fix memory leak in alloc_kmemlistChristoph Lameter2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | We have had this memory leak for a while now. The situation is complicated by the use of alloc_kmemlist() as a function to resize various caches by do_tune_cpucache(). What we do here is first of all make sure that we deallocate properly in the loop over all the nodes. If we are just resizing caches then we can simply return with -ENOMEM if an allocation fails. If the cache is new then we need to rollback and remove all earlier allocations. We detect that a cache is new by checking if the link to the global cache chain has been setup. This is a bit hackish .... (also fix up too overlong lines that I added in the last patch...)

* [PATCH] slab: Bypass free lists for __drain_alien_cache()Christoph Lameter2006-03-25
| | | | | | | | | | | | | | | | | | __drain_alien_cache() currently drains objects by freeing them to the (remote) freelists of the original node. However, each node also has a shared list containing objects to be used on any processor of that node. We can avoid a number of remote node accesses by copying the pointers to the free objects directly into the remote shared array. And while we are at it: Skip alien draining if the alien cache spinlock is already taken. Kiran reported that this is a performance benefit.

* [PATCH] Validate and sanitze itimer timeval from userspaceThomas Gleixner2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the specification the timevals must be validated and an errorcode -EINVAL returned in case the timevals are not in canonical form. This check was never done in Linux. The pre 2.6.16 code converted invalid timevals silently. Negative timeouts were converted by the timeval_to_jiffies conversion to the maximum timeout. hrtimers and the ktime_t operations expect timevals in canonical form. Otherwise random results might happen on 32 bits machines due to the optimized ktime_add/sub operations. Negative timeouts are treated as already expired. This might break applications which work on pre 2.6.16. To prevent random behaviour and API breakage the timevals are checked and invalid timevals sanitized in a simliar way as the pre 2.6.16 code did. Invalid timevals are reported with a per boot limited number of kernel messages so applications which use this misfeature can be corrected. After a grace period of one year the sanitizing should be replaced by a correct validation check. This is also documented in Documentation/feature-removal-schedule.txt The validation and sanitizing is done inside do_setitimer so all callers (sys_setitimer, compat_sys_setitimer, osf_setitimer) are catched.

* [PATCH] sys_alarm() unsigned signed conversion fixupThomas Gleixner2006-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | alarm() calls the kernel with an unsigend int timeout in seconds. The value is stored in the tv_sec field of a struct timeval to setup the itimer. The tv_sec field of struct timeval is of type long, which causes the tv_sec value to be negative on 32 bit machines if seconds > INT_MAX. Before the hrtimer merge (pre 2.6.16) such a negative value was converted to the maximum jiffies timeout by the timeval_to_jiffies conversion. It's not clear whether this was intended or just happened to be done by the timeval_to_jiffies code. hrtimers expect a timeval in canonical form and treat a negative timeout as already expired. This breaks the legitimate usage of alarm() with a timeout value > INT_MAX seconds. For 32 bit machines it is therefor necessary to limit the internal seconds value to avoid API breakage. Instead of doing this in all implementations of sys_alarm the duplicated sys_alarm code is moved into a common function in itimer.c Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [PATCH] libata: Remove dependence on host_set->dev for SASBrian King2006-03-24
| | | | | | | | | | | | | | | | | | Remove some of the dependence on the host_set struct in preparation for supporting SAS HBAs. Adds a struct device pointer to the ata_port struct. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: ata_scsi_ioctl cleanupBrian King2006-03-24
| | | | | | | | | | | | | | | | | | In preparation for SAS, kill some unnecessary code in ata_scsi_ioctl to find the ATA port and device given the scsi_device. Neither local is used in the function. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * [PATCH] Make libata not powerdown drivers on PM_EVENT_FREEZE.Nigel Cunningham2006-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment libata doesn't pass pm_message_t down ata_device_suspend. This causes drives to be powered down when we just want a freeze, causing unnecessary wear and tear. This patch gets pm_message_t passed down so that it can be used to determine whether to power down the drive.

| * [PATCH] libata: make ata_set_mode() responsible for failure handlingTejun Heo2006-03-24
| | | | | | | | | | | | | | | | | | | | | | Make ata_set_mode() responsible for determining whether to take port or device offline on failure. ata_dev_set_xfermode() and ata_dev_set_mode() indicate error to the caller instead of disabling port directly on failure. Also, for consistency, ata_dev_present() check is done in ata_set_mode() instead of ata_dev_set_mode(). Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: use ata_dev_disable() in ata_bus_probe()Tejun Heo2006-03-24
| | | | | | | | | | | | | | | | | | We may or may not disable a device after ata_dev_configure() fails. Kill 'not supported, ignoring' message in ata_dev_configure() and use ata_dev_disable() in ata_bus_probe(). Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: implement ata_dev_disable()Tejun Heo2006-03-24
| | | | | | | | | | | | | | | | | | | | | | This patch implements ata_dev_disable() which prints a warning message and takes @dev offline. Currently, this is done by explicitly incrementing dev->class with case-by-case warning messages. Giving user clear indication when libata gives up will be more important as libata will be doing more retries. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: check if port is disabled after internal commandTejun Heo2006-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libata core is being changed to disallow port/device disable on lower layers. However, some LLDDs (sata_mv) directly disable port on command failure. This patch makes ata_exec_internal() check whether a port got disabled after an internal command. If it is, AC_ERR_SYSTEM is added to err_mask and the port gets re-enabled. As internal command failure results in device disable for drivers which don't implement newer reset/EH callbacks, this change results in no behavior change for single device per port controllers. For slave-possible LLDDs which disable port on command failure, (1) such drivers don't exist currently, (2) issuing command to the other device of once-disabled port shouldn't result in catastrophe even if such driver exists. So, this should be enough as a temporary measure. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: make per-dev transfer mode limits per-devTejun Heo2006-03-24
| | | | | | | | | | | | | | | | Now that each ata_device has xfer masks, per-dev limits can be made per-dev instead of per-port. Make per-dev limits per-dev. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: add per-dev pio/mwdma/udma_maskTejun Heo2006-03-24
| | | | | | | | | | | | | | | | | | | | Add per-dev pio/mwdma/udma_mask. All transfer mode limits used to be applied to ap->*_mask which unnecessarily restricted other devices sharing the port. This change will also benefit later EH speed down and hotplug. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
