* [PATCH] Align the node_mem_map endpoints to a MAX_ORDER boundaryBob Picco2006-05-212-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | Andy added code to buddy allocator which does not require the zone's endpoints to be aligned to MAX_ORDER. An issue is that the buddy allocator requires the node_mem_map's endpoints to be MAX_ORDER aligned. Otherwise __page_find_buddy could compute a buddy not in node_mem_map for partial MAX_ORDER regions at zone's endpoints. page_is_buddy will detect that these pages at endpoints are not PG_buddy (they were zeroed out by bootmem allocator and not part of zone). Of course the negative here is we could waste a little memory but the positive is eliminating all the old checks for zone boundary conditions. SPARSEMEM won't encounter this issue because of MAX_ORDER size constraint when SPARSEMEM is configured. ia64 VIRTUAL_MEM_MAP doesn't need the logic either because the holes and endpoints are handled differently. This leaves checking alloc_remap and other arches which privately allocate for node_mem_map.

* [PATCH] s390: next_timer_interrupt overflow in stop_hz_timerMartin Schwidefsky2006-05-211-1/+1
| | | | | | | | | | | | | | The 32 bit unsigned substraction (next - jiffies) in stop_hz_timer can overflow if jiffies gets advanced between next_timer_interrupt and the read under the xtime lock. The cast to a u64 then results in a large value which causes the cpu to wait too long. Fix this by casting next and jiffies independently to u64 before subtracting them.

* [PATCH] Fix a NO_IDLE_HZ timer bugZachary Amsden2006-05-211-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | Under certain timing conditions, a race during boot occurs where timer ticks are being processed on remote CPUs. The remote timer ticks can increment jiffies, and if this happens during a window when a timeout is very close to expiring but a local tick has not yet been delivered, you can end up with 1) No softirq pending 2) A local timer wheel which is not synced to jiffies 3) No high resolution timer active 4) A local timer which is supposed to fire before the current jiffies value. In this circumstance, the comparison in next_timer_interrupt overflows, because the base of the comparison for high resolution timers is jiffies, but for the softirq timer wheel, it is relative the the current base of the wheel (jiffies_base).

* [PATCH] i386 kdump boot cpu physical apicid fixVivek Goyal2006-05-211-0/+8
| | | | | | | | | | | | | | | | | | | | | | | o Kdump second kernel boot fails after a system crash if second kernel is UP and acpi=off and if crash occurred on a non-boot cpu. o Issue here is that MP tables report boot cpu lapic id as 0 but second kernel is booting on a different processor and MP table data is stale in this context. Hence apic_id_registered() check fails in setup_local_APIC() when called from APIC_init_uniprocessor(). o Problem is not seen if ACPI is enabled as in that case boot_cpu_physical_apicid is read from the LAPIC. o Problem is not seen with SMP kernels as well because in this case also boot_cpu_physical_apicid is read from LAPIC. (smp_boot_cpus()). o The problem is fixed by reading boot_cpu_physical_apicid from LAPIC if it is a UP kernel and CRASH_DUMP is enabled.

* [PATCH] Cpuset: might sleep checking zones allowed fixPaul Jackson2006-05-211-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a couple of infrequently encountered 'sleeping function called from invalid context' in the cpuset hooks in __alloc_pages. Could sleep while interrupts disabled. The routine cpuset_zone_allowed() is called by code in mm/page_alloc.c __alloc_pages() to determine if a zone is allowed in the current tasks cpuset. This routine can sleep, for certain GFP_KERNEL allocations, if the zone is on a memory node not allowed in the current cpuset, but might be allowed in a parent cpuset. But we can't sleep in __alloc_pages() if in interrupt, nor if called for a GFP_ATOMIC request (__GFP_WAIT not set in gfp_flags). The rule was intended to be: Don't call cpuset_zone_allowed() if you can't sleep, unless you pass in the __GFP_HARDWALL flag set in gfp_flag, which disables the code that might scan up ancestor cpusets and sleep. This rule was being violated in a couple of places, due to a bogus change made (by myself, pj) to __alloc_pages() as part of the November 2005 effort to cleanup its logic, and also due to a later fix to constrain which swap daemons were awoken. The bogus change can be seen at: http://linux.derkeiler.com/Mailing-Lists/Kernel/2005-11/4691.html [PATCH 01/05] mm fix __alloc_pages cpuset ALLOC_* flags This was first noticed on a tight memory system, in code that was disabling interrupts and doing allocation requests with __GFP_WAIT not set, which resulted in __might_sleep() writing complaints to the log "Debug: sleeping function called ...", when the code in cpuset_zone_allowed() tried to take the callback_sem cpuset semaphore. We haven't seen a system hang on this 'might_sleep' yet, but we are at decent risk of seeing it fairly soon, especially since the additional cpuset_zone_allowed() check was added, conditioning wakeup_kswapd(), in March 2006.

* [PATCH] pci: correctly allocate return buffers for osc callsKristen Accardi2006-05-211-25/+35
| | | | | | | | | | | | | | | | | | The OSC set and query functions do not allocate enough space for return values, and set the output buffer length to a false, too large value. This causes the acpi-ca code to assume that the output buffer is larger than it actually is, and overwrite memory when copying acpi return buffers into this caller provided buffer. In some cases this can cause kernel oops if the memory that is overwritten is a pointer. This patch will change these calls to use a dynamically allocated output buffer, thus allowing the acpi-ca code to decide how much space is needed.

* [PATCH] binfmt_flat: don't check for EMFILEAndrew Morton2006-05-211-21/+9
| | | | | | | | | | | | | | | | | Bernd Schmidt points out that binfmt_flat is now leaving the exec file open while the application runs. This offsets all the application's fd numbers. We should have closed the file within exec(), not at exit()-time. But there doesn't seem to be a lot of point in doing all this just to avoid going over RLIMIT_NOFILE by one fd for a few microseconds. So take the EMFILE checking out again. This will cause binfmt_flat to again fail LTP's exec-should-return-EMFILE-when-fdtable-is-full test. That test appears to be wrong anyway - Open Group specs say nothing about exec() returning EMFILE.

* [PATCH] NFS server subtree_check returns dubious valuePeter Staubach2006-05-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Address a problem found when a Linux NFS server uses the "subtree_check" export option. The "subtree_check" NFS export option was designed to prohibit a client from using a file handle for which it should not have permission. The algorithm used is to ensure that the entire path to the file being referenced is accessible to the user attempting to use the file handle. If some part of the path is not accessible, then the operation is aborted and the appropriate version of ESTALE is returned to the NFS client. The error, ESTALE, is unfortunate in that it causes NFS clients to make certain assumptions about the continued existence of the file. They assume that the file no longer exists and refuse to attempt to access it again. In this case, the file really does exist, but access was denied by the server for a particular user. A better error to return would be an EACCES sort of error. This would inform the client that the particular operation that it was attempting was not allowed, without the nasty side effects of the ESTALE error.

Without this, the mac ide code can cause the ide probing code to explode in flames in sysfs registration due to what looks like a stale pointer in there (happens when removing/re-inserting one of the hotswap media bays on some laptops).

* [PATCH] matroxfb: fix DVI setup to be more compatiblePaul A. Clarke2006-05-213-2/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There has been a longstanding problem with the Matrox G450 and perhaps other similar cards, with modes "above" 1280x1024-60 on ppc/ppc64 boxes running Linux. Higher resolutions and/or higher refresh rates resulted in a very noticably "jittery" display, and sometimes no display, depending on the physical monitor. This patch fixes that problem on the systems I have easy access to... I've tested with SLES9SP3 (2.6.5+ kernel) and 2.6.16-rc6 custom kernels on an IBM eServer p5 520 w/G450 (a.k.a GXT135P on IBM's ppc64 systems), and a colleague of mine (Ian Romanick) tested it successfully on an Apple ppc32 box (w/GXT135P). I also tested it on IA32 box I have with a GXT135P to verify that it didn't obviously break anything. In my testing, I covered single-card, single and dual-head setups using both HD15 and DVI-D signals, on both the IA32 and ppc64 boxes. While everything appeared fine on both boxes, I did encounter one problem: I can't get any signal on the DVI-D output on the ppc64 box. However, this is also the case without my patch. I just noticed that screen-blanking only occurs on the primary display as well. Signed-off-by: Paul A.

* [PATCH] NFS: fix error handling on access_ok in compat_sys_nfsservctlLin Feng Shen2006-05-211-85/+92
| | | | | | | | | | | | | | | | | | | | | | | Functions compat_nfs_svc_trans, compat_nfs_clnt_trans, compat_nfs_exp_trans, compat_nfs_getfd_trans and compat_nfs_getfs_trans, which are called by compat_sys_nfsservctl(fs/compat.c), don't handle the return value of access_ok properly. access_ok return 1 when the addr is valid, and 0 when it's not, but these functions have the reversed understanding. When the address is valid, they always return -EFAULT to compat_sys_nfsservctl. An example is to run /usr/sbin/rpc.nfsd(32bit program on Power5). It doesn't function as expected. strace showes that nfsservctl returns -EFAULT. The patch fixes this by correcting the error handling on the return value of access_ok in the five functions.
