2012-05-20m68knommu: switch to GPIO init macros in ColdFire 5407 init codeGreg Ungerer1-15/+1
Modify the GPIO setup table to use the mcfgpio.h macros for table init. Simplifies code and reduces line count significantly. Signed-off-by: Greg Ungerer <[email protected]> Acked-by: Steven King <[email protected]>

2012-05-20m68knommu: switch to GPIO init macros in ColdFire 528x init codeGreg Ungerer2-503/+103
Modify the GPIO setup table to use the mcfgpio.h macros for table init. Simplifies code and reduces line count significantly. We also need to rename some of the GPIO registers to be consistent with all other ColdFire parts (we can't use the new GPIO macros otherwise).

2012-05-20m68knommu: introduce macros to simplify ColdFire GPIO table initializationGreg Ungerer1-0/+54
We have very large tables in the ColdFire CPU GPIO setup code that essentially boil down to 2 distinct types of GPIO pin initiaization. Using 2 macros we can reduce these large tables to at most a dozen lines of setup code, and in quite a few cases a single table entry. Introduce these 2 macros into the existing mcfgpio.h header.

2012-05-20m68k: merge the MMU and non-MMU signal.c codeGreg Ungerer3-1882/+1199
The MMU (signal_mm.c) and non-MMU (signal_no.c) versions of the m68k architecture signal handling code are very similar. Most of their code is the same. Merge the two back into a single signal.c, and move some of the code around inside the file to minimize the number of #ifdefs required. Specificially we can group out the CONFIG_FPU and the CONFIG_MMU code. We end up needing a few other "#ifdef CONFIG_MMU" as well, but not too many.

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 Dickins1-1/+1
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 Dumazet1-1/+4
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.
