From: Stephen Smalley <sds@epoch.ncsc.mil> This patch fixes the type of the ssec pointer in the sk_free_security function. This has no current impact as the magic element is the top of each structure. Thanks to Chad Hanson of TCS for discovering the bug and submitting the patch.

From: "Nguyen, Tom L" <tom.l.nguyen@intel.com> Adds MSI support for ia64. - Modified existing code in drivers/pci/msi.c and drivers/pci/msi.h to include MSI support on IA64 platform. - Based on the comments received from Zwane Mwaikambo and David Mosberger, this patch consolidates the vector allocators as assign_irq_vector(AUTO_ASSIGN) has the same semantics as ia64_alloc_vector() by converting the existing uses of ia64_alloc_vector() to assign_irq_vector(AUTO_ASSIGN). - Based on the comments received from Zwane Mwaikambo, this patch consolidates the semantics of vector allocator assign_irq_vector() in drivers/pci/msi.c into the relevant architecture's vector allocator assign_irq_vector() in arch/i386/kernel/io_apic.c. - Regarding vector allocation, this patch modifies the existing function assign_irq_vector() to maximize the number of allocated vectors to 188 before going -ENOSPC. - Based on your comments, this patch creates <asm-i386/msi.h>, <asm-ia64/msi.h> and <asm-x86_64/msi.h>, includes <asm/msi.h> from within drivers/pci/msi.h and then places all the code which is currently under ifdef in msi.h into the relevant architecture's <asm/msi.h> file. - Based on your comments, this patch places pci_vector_resources() in existing drivers/pci/msi.c in the relevant architecture implementations such as into arch/.../pci/irq.c.

From: James Cleverdon <jamesclv@us.ibm.com> Break out the definition of NR_IRQ_VECTORS, etc from irq_vectors.h into irq_vectors_limits.h, so we can change it per subarch without having code duplication for the rest of the file. Stick the same values back for mach-default, and override them for mach-summit/generic which needs bigger limits.

From: Rusty Russell <rusty@rustcorp.com.au> Agustin Martin <agmartin@debian.org> pointed out that this doesn't work: options ide-mod options="ide=nodma hdc=cdrom" The quotes are understood by kernel/params.c (ie. it skips over spaces inside them), but are not stripped before handing to the underlying function. They should be.

From: Hugh Dickins <hugh@veritas.com> Kevin P. Fleming pointed out that the 2.6 tmpfs does not allow writing huge sparse files. This is an unintended side-effect of the strict memory commit changes: which should make no difference. The solution is to treat the tmpfs files (of variable size) and the shmem objects (of fixed size) differently: sounds nasty but works out well. The shmem objects follow the VM preallocation convention as before, but the tmpfs files revert to allocation on demand as a filesystem would. If there's not enough memory to write to a tmpfs hole, it is reported as -ENOSPC rather than -ENOMEM, so the mmap writer gets SIGBUS rather than everyone else getting OOM-killed.

From: William Lee Irwin III <wli@holomorphy.com> Chang bitmap_shift_left()/bitmap_shift_right() to have O(1) stackspace requirements. Given zeroed tail preconditions these implementations satisfy zeroed tail postconditions, which makes them compatible with whatever changes from Paul Jackson one may want to merge in the future. No particular effort was required to ensure this. A small (but hopefully forgiveable) cleanup is a spelling correction: s/bitmap_shift_write/bitmap_shift_right/ in one of the kerneldoc comments. The primary effect of the patch is to remove the MAX_BITMAP_BITS limitation, so restoring the NR_CPUS to be limited only by stackspace and slab allocator maximums. They also look vaguely more efficient than the current code, though as this was not done for performance reasons, no performance testing was done.

From: Marcelo Tosatti <marcelo.tosatti@cyclades.com> From: Alain Knaff <alain.knaff@lll.lu> This patch adds support for floppy disks whose sectors are numbered starting at 0 rather than 1 as usual disks would be. This format is used for some CP/M disks, and also for certain music samplers (such as Ensoniq Ensoniq EPS 16plus). In order to use it, you need an fdutils with the current patch from http://fdutils.linux.lu as well, and then do setfdrpm /dev/fd0 dd zerobased sect=10 or setfdprm /dev/fd0 hd zerobased sect. In addtion, the patch also fixes my email addresses. I no longer use pobox.com.

From: Rusty Russell <rusty@rustcorp.com.au> Brian Gerst's patch which moved __this_module out from module.h into the module post-processing had a side effect. genksyms didn't see the undefined symbols for modules without a module_init (or module_exit), and hence didn't generate a version for them, causing the kernel to be tainted. The simple solution is to always include the versions for these functions. Also includes two cleanups: 1) alloc_symbol is easier to use if it populates ->next for us. 2) add_exported_symbol should set owner to module, not head of module list (we don't use this field in entries in that list, fortunately).

From: David Mosberger <davidm@napali.hpl.hp.com> Somebody recently pointed out a performance-anomaly to me where an unusual amount of time was being spent reading from /dev/urandom. The problem isn't really surprising as it happened only on >= 4-way machines and the random driver isn't terribly scalable the way it is written today. If scalability _really_ mattered, I suppose per-CPU data structures would be the way to go. However, I found that at least for 4-way machines, performance can be improved considerably with the attached patch. In particular, I saw the following performance on a 4-way ia64 machine: Test: 3 tasks running "dd if=/dev/urandom of=/dev/null bs=1024": throughput:

From: Arjan van de Ven <arjanv@redhat.com> The patch below adds a few missing put_user()'s to the i810/i830 drm modules. Users reported oopses with 4g/4g split in action, and sparse annotations indeed found the offender in the function in question. I've kept the sparse __user annotations since those are generally useful anyway. I can't test it myself but a few people reported that the oopses went away so far.

From: Rusty Russell <rusty@rustcorp.com.au> From: colpatch@us.ibm.com The cpu_2_node[] array for i386 is initialized to all 0's, meaning that until modified at CPU bring-up, all CPUs are mapped to node 0. When CPUs are brought online, they are mapped to the appropriate node by various mechanisms, depending on the underlying hardware. When we unmap CPUs (hotplug time), we should return the mapping for the CPU that is going away to its original state, ie: 0. When this code was initially submitted, the misguided poster (me) made the mistake of putting a -1 in the cpu_2_node[] array for the CPU going away. This patch fixes this mistake, and allows code to get a valid node number for all valid CPU numbers. This is important, because most (if not all) callers do not error check the value returned by the cpu_to_node() macro, and they should not have to. The API specifies that a valid node number be returned for any valid CPU number.

From: Rusty Russell <rusty@rustcorp.com.au> From: Andreas Schwab <schwab@suse.de> I'm getting a warning when building for ia64 with MODVERSIONS enabled. This is a bug in genksyms, it can't cope with some arguments of __typeof__. The following patch will fix that. Actually the argument of __typeof__ is an abstract declarator, but the genksyms parser has no production for that; decl_specifier_seq also matches some invalid constructs, but I don't think this is a problem in practice, since the compiler will reject them.
