2009-01-18System call wrapper special casesHeiko Carstens
commit 6673e0c3fbeaed2cd08e2fd4a4aa97382d6fedb0 upstream. System calls with an unsigned long long argument can't be converted with the standard wrappers since that would include a cast to long, which in turn means that we would lose the upper 32 bit on 32 bit architectures. Also semctl can't use the standard wrapper since it has a 'union' parameter. So we handle them as special case and add some extra wrappers instead.

2009-01-18inotify: fix type errors in interfacesMichael Kerrisk
commit 4ae8978cf92a96257cd8998a49e781be83571d64 upstream. The problems lie in the types used for some inotify interfaces, both at the kernel level and at the glibc level. This mail addresses the kernel problem. I will follow up with some suggestions for glibc changes. For the sys_inotify_rm_watch() interface, the type of the 'wd' argument is currently 'u32', it should be '__s32' . That is Robert's suggestion, and is consistent with the other declarations of watch descriptors in the kernel source, in particular, the inotify_event structure in include/linux/inotify.h: struct inotify_event { __s32 wd; /* watch descriptor */ __u32 mask; /* watch mask */ __u32 cookie; /* cookie to synchronize two events */ __u32 len; /* length (including nulls) of name */ char name[0]; /* stub for possible name */ }; The patch makes the changes needed for inotify_rm_watch().

2009-01-18x86, UV: remove erroneous BAU initializationCliff Wickman
commit 46814dded1b972a07b1609d81632eef3009fbb10 upstream. Impact: fix crash on x86/UV UV is the SGI "UltraViolet" machine, which is x86_64 based. BAU is the "Broadcast Assist Unit", used for TLB shootdown in UV. This patch removes the allocation and initialization of an unused table. This table is left over from a development test mode. It is unused in the present code. And it was incorrectly initialized: 8 entries allocated but 17 initialized, causing slab corruption.

2009-01-18x86: fix incorrect __read_mostly on _boot_cpu_pdaRavikiran G Thirumalai
commit 26799a63110dcbe81291ea53178f6b4810d07424 upstream. The pda rework (commit 3461b0af025251bbc6b3d56c821c6ac2de6f7209) to remove static boot cpu pdas introduced a performance bug. _boot_cpu_pda is the actual pda used by the boot cpu and is definitely not "__read_mostly" and ended up polluting the read mostly section with writes. This bug caused regression of about 8-10% on certain syscall intensive workloads.

Upstream commit cf558d25e5c9f70fa0279c9b7b8b4aed7cae9bd4 Under special circumstances the IOMMU does not reset the head and tail pointer of its command ringbuffer to zero when the command base is written. This causes the IOMMU to fetch random memory and executes it as an command. Since these commands are likely illegal IOMMU stops fetching further commands including IOTLB flushes. This leads to completion wait errors at boot and in some cases to data corruption and kernel crashes.

2009-01-14cciss: fix problem that deleting multiple logical drives could cause a panicStephen M. Cameron
commit d8a0be6ab7ba1ffa43e7ea0dcdde3e8b68d4f762 upstream. Fix problem that deleting multiple logical drives could cause a panic. It fixes a panic which can be easily reproduced in the following way: Just create several "arrays," each with multiple logical drives via hpacucli, then delete the first array, and it will blow up in deregister_disk(), in the call to get_host() when it tries to dig the hba pointer out of a NULL queue pointer.

commit a2ed9615e3222645007fc19991aedf30eed3ecfd upstream. When we read the write-intent-bitmap off the device, we currently read a whole number of pages. When PAGE_SIZE is 4K, this works due to the alignment we enforce on the superblock and bitmap. When PAGE_SIZE is 64K, this case read past the end-of-device which causes an error. When we write the superblock, we ensure to clip the last page to just be the required size. Copy that code into the read path to just read the required number of sectors.

commit a06d568f7c5e40e34ea64881842deb8f4382babf upstream. Mapping the destination multiple times is a misuse of the dma-api. Since the destination may be reused as a source, ensure that it is only mapped once and that it is mapped bidirectionally. This appears to add ugliness on the unmap side in that it always reads back the destination address from the descriptor, but gcc can determine that dma_unmap is a nop and not emit the code that calculates its arguments.
