    Pull MIPS updates from Ralf Baechle:

    o Add basic support for the Mediatek/Ralink Wireless SoC family.

    o The Qualcomm Atheros platform is extended by support for the new
    QCA955X SoC series as well as a bunch of patches that get the code
    ready for OF support.

    o Lantiq and BCM47XX platform have a few improvements and bug fixes.

    o MIPS has sent a few patches that get the kernel ready for the
    upcoming microMIPS support.

    o The rest of the series is made up of small bug fixes and cleanups
    that relate to various parts of the MIPS code. The biggy in there is
    a whitespace cleanup. After I was sent another set of whitespace
    cleanup patches I decided it was the time to clean the whitespace
    "issues" for once and and that touches many files below arch/mips/.

    Fix up silly conflicts, mostly due to whitespace cleanups.

  • b67bfe0d4   hlist: drop the node parameter from iterators ... Browse Code »

    I'm not sure why, but the hlist for each entry iterators were conceived

    list_for_each_entry(pos, head, member)

    The hlist ones were greedy and wanted an extra parameter:

    hlist_for_each_entry(tpos, pos, head, member)

    Why did they need an extra pos parameter? I'm not quite sure. Not only
    they don't really need it, it also prevents the iterator from looking
    exactly like the list iterator, which is unfortunate.

    Besides the semantic patch, there was some manual work required:

    - Fix up the actual hlist iterators in linux/list.h
    - Fix up the declaration of other iterators based on the hlist ones.
    - A very small amount of places were using the 'node' parameter, this
    was modified to use 'obj->member' instead.
    - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
    properly, so those had to be fixed up manually.

    The semantic patch which is mostly the work of Peter Senna Tschudin is here:

    iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host;

  • 535237cec   MIPS: remove broken conditional inside vpe loader code ... Browse Code »

    The commit [1] breaks builds and results in the following error

    arch/mips/kernel/vpe.c: In function 'vpe_run':
    arch/mips/kernel/vpe.c:708:16: error: invalid type argument of '->' (have 'struct list_head')

    Taking a closer look at the conditional we notice that list_first_entry wont
    ever return NULL. The easiest fix is to just drop the dead code.

    We cannot use __init for earlyprintk code or data, since the kernel

    Currently MIPS will crash/hang/die if you use keep_bootcon. The patch
    fixes it at least on Lemote FuLoong mini-PC. Changes for other boards
    were done based on what I could find with grep...

    /proc/vmcore wasn't showing up in kdump kernels. It turns that that
    for Octeon, the memory used by elfcorehdr wasn't being set aside
    properly and it was getting clobbered before /proc/vmcore could get
    it. So reserve the memory if it shows up in a memory area managed
    by the kernel.

    Note to application programmers: this indicates the CPU's ISA level
    It does not imply the current execution environment does support it. For
    example an O32 application seeing "mips64r2" would still be restricted by
    by the execution environment to 32-bit - but the kernel could run mips64r2
