Move tcp_try_coalesce() protocol independent part to skb_try_coalesce(). skb_try_coalesce() can be used in IPv4 defrag and IPv6 reassembly, to build optimized skbs (less sk_buff, and possibly less 'headers') skb_try_coalesce() is zero copy, unless the copy can fit in destination header (its a rare case) kfree_skb_partial() is also moved to net/core/skbuff.c and exported, because IPv6 will need it in patch (ipv6: use skb coalescing in reassembly).

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 linker bug workarounds from Peter Anvin. GNU ld-2.22.52.0.[12] (*) has an unfortunate bug where it incorrectly turns certain relocation entries absolute. Section-relative symbols that are part of otherwise empty sections are silently changed them to absolute. We rely on section-relative symbols staying section-relative, and actually have several sections in the linker script solely for this purpose. See for example http://sourceware.org/bugzilla/show_bug.cgi?id=14052 We could just black-list the buggy linker, but it appears that it got shipped in at least F17, and possibly other distros too, so it's sadly not some rare unusual case. This backports the workaround from the x86/trampoline branch, and as Peter says: "This is not a minimal fix, not at all, but it is a tested code base." * 'x86/ld-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, relocs: When printing an error, say relative or absolute x86, relocs: Workaround for binutils 2.22.52.0.1 section bug x86, realmode: 16-bit real-mode code support for relocs tool (*) That's a manly release numbering system.

2012-05-19memcg,thp: fix res_counter:96 regressionHugh Dickins
Occasionally, testing memcg's move_charge_at_immigrate on rc7 shows a flurry of hundreds of warnings at kernel/res_counter.c:96, where res_counter_uncharge_locked() does WARN_ON(counter->usage < val). The first trace of each flurry implicates __mem_cgroup_cancel_charge() of mc.precharge, and an audit of mc.precharge handling points to mem_cgroup_move_charge_pte_range()'s THP handling in commit 12724850e806 ("memcg: avoid THP split in task migration"). Checking !mc.precharge is good everywhere else, when a single page is to be charged; but here the "mc.precharge -= HPAGE_PMD_NR" likely to follow, is liable to result in underflow (a lot can change since the precharge was estimated). Simply check against HPAGE_PMD_NR: there's probably a better alternative, trying precharge for more, splitting if unsuccessful; but this one-liner is safer for now - no kernel/res_counter.c:96 warnings seen in 26 hours.

2012-05-19ipv6: disable GSO on sockets hitting dst_allfragEric Dumazet
If the allfrag feature has been set on a host route (due to an ICMPv6 Packet Too Big received indicating a MTU of less than 1280), we hit a very slow behavior in TCP stack, because all big packets are dropped and only a retransmit timer is able to push one MSS frame every 200 ms. One way to handle this is to disable GSO on the socket the first time a super packet is dropped. Adding a specific dst_allfrag() in the fast path is probably overkill since the dst_allfrag() case almost never happen.

2012-05-18ipv6: ip6_fragment() should check CHECKSUM_PARTIALEric Dumazet
Quoting Tore Anderson from : If the allfrag feature has been set on a host route (due to an ICMPv6 Packet Too Big received indicating a MTU of less than 1280), TCP SYN/ACK packets to that destination appears to get an incorrect TCP checksum. This in turn means they are thrown away as invalid. In the case of an IPv4 client behind a link with a MTU of less than 1260, accessing an IPv6 server through a stateless translator, this means that the client can only download a single large file from the server, because once it is in the server's routing cache with the allfrag feature set, new TCP connections can no longer be established. </endquote> It appears ip6_fragment() doesn't handle CHECKSUM_PARTIAL properly. As network drivers are not prepared to fetch correct transport header, a safe fix is to call skb_checksum_help() before fragmenting packet.

2012-05-18x86, realmode: 16-bit real-mode code support for relocs toolH. Peter Anvin
A new option is added to the relocs tool called '--realmode'. This option causes the generation of 16-bit segment relocations and 32-bit linear relocations for the real-mode code. When the real-mode code is moved to the low-memory during kernel initialization, these relocation entries can be used to relocate the code properly. In the assembly code 16-bit segment relocations must be relative to the 'real_mode_seg' absolute symbol. Linear relocations must be relative to a symbol prefixed with 'pa_'. 16-bit segment relocation is used to load cs:ip in 16-bit code. Linear relocations are used in the 32-bit code for relocatable data references. They are declared in the linker script of the real-mode code. The relocs tool is moved to arch/x86/tools/relocs.c, and added new target archscripts that can be used to build scripts needed building an architecture. be compiled before building the arch/x86 tree.

2012-05-19dm thin: fix table output when pool target disables discard passdown internallyMike Snitzer
When the thin pool target clears the discard_passdown parameter internally, it incorrectly changes the table line reported to userspace. This breaks dumb string comparisons on these table lines in generic userspace device-mapper library code and leads to tables being reloaded repeatedly when nothing is actually meant to be changing. This patch corrects this by no longer changing the table line when discard passdown was disabled. We can still tell when discard passdown is overridden by looking for the message "Discard unsupported by data device (sdX): Disabling discard passdown." This automatic detection is also moved from the 'load' to the 'resume' so that it is re-evaluated should the properties of underlying devices change.

2012-05-18proc: move fd symlink i_mode calculations into tid_fd_revalidate()Linus Torvalds
Instead of doing the i_mode calculations at proc_fd_instantiate() time, move them into tid_fd_revalidate(), which is where the other inode state (notably uid/gid information) is updated too. Otherwise we'll end up with stale i_mode information if an fd is re-used while the dentry still hangs around. Not that anything really *cares* (symlink permissions don't really matter), but Tetsuo Handa noticed that the owner read/write bits don't always match the state of the readability of the file descriptor, and we _used_ to get this right a long time ago in a galaxy far, far away. Besides, aside from fixing an ugly detail (that has apparently been this way since commit 61a28784028e: "proc: Remove the hard coded inode numbers" in 2006), this removes more lines of code than it adds. And it just makes sense to update i_mode in the same place we update i_uid/gid. Al Viro correctly points out that we could just do the inode fill in the inode iops ->getattr() function instead. However, that does require somewhat slightly more invasive changes, and adds yet *another* lookup of the file descriptor. We need to do the revalidate() for other reasons anyway, and have the file descriptor handy, so we might as well fill in the information at this point.
