2006-05-02[PATCH] vmsplice: fix badly placed end paranthesisJens Axboe
We need to use the minium of {len, PAGE_SIZE-off}, not {len, PAGE_SIZE}-off. The latter doesn't make any sense, and could cause us to attempt negative length transfers... Signed-off-by: Jens Axboe <axboe@suse.de>

2006-05-01[NETFILTER] x_tables: fix compat related crash on non-x86Patrick McHardy
When iptables userspace adds an ipt_standard_target, it calculates the size of the entire entry as: sizeof(struct ipt_entry) + XT_ALIGN(sizeof(struct ipt_standard_target)) ipt_standard_target looks like this: struct xt_standard_target { struct xt_entry_target target; int verdict; }; xt_entry_target contains a pointer, so when compiled for 64 bit the structure gets an extra 4 byte of padding at the end. On 32 bit architectures where iptables aligns to 8 byte it will also have 4 byte padding at the end because it is only 36 bytes large. The compat_ipt_standard_fn in the kernel adjusts the offsets by sizeof(struct ipt_standard_target) - sizeof(struct compat_ipt_standard_target), which will always result in 4, even if the structure from userspace was already padded to a multiple of 8. On x86 this works out by accident because userspace only aligns to 4, on all other architectures this is broken and causes incorrect adjustments to the size and following offsets. Thanks to Linus for lots of debugging help and testing. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-05-01[PATCH] x86_64: make PC Speaker driver workMikael Pettersson
The PC Speaker driver's ->probe() routine doesn't even get called in the 64-bit kernels. The reason for that is that the arch code apparently has to explictly add a "pcspkr" platform device in order for the driver core to call the ->probe() routine. arch/i386/kernel/setup.c unconditionally adds a "pcspkr" device, but the x86_64 kernel has no code at all related to the PC Speaker. The patch below copies the relevant code from i386 to x86_64, which makes the PC Speaker work for me on x86_64.

Change of_node_to_nid() to traverse the device tree, looking for a numa id. Cell uses this to assign ids to SPUs, which are children of the CPU node. Existing users of of_node_to_nid() are altered to use of_node_to_nid_single(), which doesn't do the traversal. Export an attach_sysdev_to_node() function, allowing system devices (eg.

Based on an older patch from Mike Kravetz <kravetz@us.ibm.com> We need to have a mem_map for high addresses in order to make fops->no_page work on spufs mem and register files. So far, we have used the memory_present() function during early bootup, but that did not work when CONFIG_NUMA was enabled. We now use the __add_pages() function to add the mem_map when loading the spufs module, which is a lot nicer.

2006-05-01[PATCH] page migration: Fix fallback behavior for dirty pagesChristoph Lameter
Currently we check PageDirty() in order to make the decision to swap out the page. However, the dirty information may be only be contained in the ptes pointing to the page. We need to first unmap the ptes before checking for PageDirty(). If unmap is successful then the page count of the page will also be decreased so that pageout() works properly. This is a fix necessary for 2.6.17. Without this fix we may migrate dirty pages for filesystems without migration functions. Filesystems may keep pointers to dirty pages. Migration of dirty pages can result in the filesystem keeping pointers to freed pages. Unmapping is currently not be separated out from removing all the references to a page and moving the mapping. Therefore try_to_unmap will be called again in migrate_page() if the writeout is successful. However, it wont do anything since the ptes are already removed. The coming updates to the page migration code will restructure the code so that this is no longer necessary.

2006-05-01[PATCH] uml: cleanup unprofile expression and build infrastructurePaolo 'Blaisorblade' Giarrusso
*) Rather than duplicate in various buggy ways the application of CFLAGS_NO_HARDENING and UNPROFILE (which apply to the same files), centralize it in Makefile.rules. UNPROFILE_OBJS mustn't be listed in USER_OBJS but are compiled as such. I've also verified that unprofile didn't work in the current form, because we set _c_flags directly (using CFLAGS and not USER_CFLAGS, which is wrong), which is normally used by c_flags, but we also override c_flags for all USER_OBJS, and there we don't call unprofile. Instead it only worked for unmap.o, the only one which wasn't a USER_OBJ. We need to set c_flags (which is not a public Kbuild API) to clear a lot of compilation flags like -nostdinc which Kbuild forces on everything. *) Rather than $(CFLAGS_$(notdir $@)), which expands to CFLAGS_anObj.s when building "anObj.s", use $(CFLAGS_$(*F).o) which always accesses CFLAGS_anObj.o, like done by Kbuild. *) Make c_flags apply to all targets having the same basename, rather than listing .s, .i, .lst and .o, with the use (which I tested) of $(USER_OBJS:.o=.%): c_flags = ... and of - $(obj)/unmap.c: _c_flags = ... + $(obj)/unmap.%: _c_flags = ...
