* [PATCH] x86: HUGETLBFS and DEBUG_PAGEALLOC are incompatibleChen, Kenneth W2006-03-251-1/+1
| | | | | | | | | | | | | DEBUG_PAGEALLOC is not compatible with hugetlb page support. That debug option turns off PSE. Once it is turned off in CR4, the cpu will ignore pse bit in the pmd and causing infinite page-not- present faults. So disable DEBUG_PAGEALLOC if the user selected hugetlbfs.

* [PATCH] x86: make CONFIG_HOTPLUG_CPU depend on !X86_PCAshok Raj2006-03-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Make CONFIG_HOTPLUG_CPU depend on !X86_PC, so we need to turn on either CONFIG_GENERICARCH, CONFIG_BIGSMP or any other subarch except X86_PC when CONFIG_HOTPLUG_CPU=y With 2.6.15+ kernels when CONFIG_HOTPLUG_CPU is turned on we switch to bigsmp mode for sending IPI's and ioapic configurations that caused the following error message. >> More than 8 CPUs detected and CONFIG_X86_PC cannot handle it. >> Use CONFIG_X86_GENERICARCH or CONFIG_X86_BIGSMP. 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. More details on why bigsmp now uses flat physical mode (vs. cluster mode) in following link. http://marc.theaimsgroup.com/?l=linux-kernel&m=113261865814107&w=2 Signed-off-by: Ashok Raj <ashok.raj@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] slab: fix memory leak in alloc_kmemlistChristoph Lameter2006-03-251-5/+28
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Lameter2006-03-251-2/+9
| | | | | | | | | | | | | | | | | | __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.

| | | | | | | | | | | | | | | | | | | The attached patch optimises d_find_alias() to only take the spinlock if there's anything in the the inode's alias list. If there isn't, it returns NULL immediately. With respect to the superblock sharing patch, this should reduce by one the number of times the dcache_lock is taken by nfs_lookup() for ordinary directory lookups. Only in the case where there's already a dentry for particular directory inode (such as might happen when another mountpoint is rooted at that dentry) will the lock then be taken the extra time.

* [PATCH] Validate and sanitze itimer timeval from userspaceThomas Gleixner2006-03-252-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Gleixner2006-03-256-61/+43
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | uevent_seqnum and uevent_helper are only defined if CONFIG_HOTPLUG=y, CONFIG_NET=n. (I stole this back from Greg's tree - it makes allnoconfig work).

* | [PATCH] strndup_user()Davi Arnaut2006-03-242-0/+39
| | | | | | | | | | | | | | | | | | | | | | This patch series creates a strndup_user() function to easy copying C strings from userspace. Also we avoid common pitfalls like userspace modifying the final \0 after the strlen_user().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the softlockup detector purely timer-interrupt driven, removing softirq-context (timer) dependencies. This means that if the softlockup watchdog triggers, it has truly observed a longer than 10 seconds scheduling delay of a SCHED_FIFO prio 99 task. (the patch also turns off the softlockup detector during the initial bootup phase and does small style fixes) Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In filesystems with the meta block group flag on, ext3_bg_num_gdb() fails to report the correct number of blocks used to store the group descriptor backups in a given group. It happens because meta_bg follows a different logic from the original ext3 backup placement in groups multiples of 3, 5 and 7.

* | [PATCH] RLIMIT_CPU: fix handling of a zero limitAndrew Morton2006-03-241-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present the kernel doesn't honour an attempt to set RLIMIT_CPU to zero seconds. But the spec says it should, and that's what 2.4.x does. Fixing this for real would involve some complexity (such as adding a new it-has-been-set flag to the task_struct, and testing that everwhere, instead of overloading the value of it_prof_expires). Given that a 2.4 kernel won't actually send the signal until one second has expired anyway, let's just handle this case by treating the caller's zero-seconds as one second.

* | [PATCH] sys_setrlimit() cleanupAndrew Morton2006-03-241-11/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Whitespace cleanups - Make that expression comprehensible. There's a potential logic change here: we do the "is it_prof_expires equal to zero" test after converting it to seconds, rather than doing the comparison between raw cputime_t's. But given that it's in units of seconds anyway, that shouldn't change anything.
