    "MIPS: PowerTV: Base files for Cisco PowerTV platform"
    nor was it ever present in the git tree so this option never worked.
    Fixes the following build problem:

  • 078a55fc8   MIPS: Delete __cpuinit/__CPUINIT usage from MIPS code ... Browse Code »

    commit 3747069b25e419f6b51395f48127e9812abc3596 upstream.

    The __cpuinit type of throwaway sections might have made sense
    some time ago when RAM was more constrained, but now the savings
    do not offset the cost and complications. For example, the fix in
    commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
    is a good example of the nasty type of bugs that can be created
    with improper use of the various __init prefixes.

    After a discussion on LKML[1] it was decided that cpuinit should go
    the way of devinit and be phased out. Once all the users are gone,
    we can then finally remove the macros themselves from linux/init.h.

    Note that some harmless section mismatch warnings may result, since
    notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
    and are flagged as __cpuinit -- so if we remove the __cpuinit from
    the arch specific callers, we will also get section mismatch warnings.
    As an intermediate step, we intend to turn the linux/init.h cpuinit
    related content into no-ops as early as possible, since that will get
    rid of these warnings. In any case, they are temporary and harmless.

    Here, we remove all the MIPS __cpuinit from C code and __CPUINIT
    from asm files. MIPS is interesting in this respect, because there
    are also uasm users hiding behind their own renamed versions of the
    __cpuinit macros.

    Pull networking changes from David S Miller:

    1) Remove the ipv4 routing cache. Now lookups go directly into the FIB
    trie and use prebuilt routes cached there.

    No more garbage collection, no more rDOS attacks on the routing
    cache. Instead we now get predictable and consistent performance,
    no matter what the pattern of traffic we service.

    This has been almost 2 years in the making. Special thanks to
    Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
    have helped along the way.

    I'm sure that with a change of this magnitude there will be some
    kind of fallout, but such things ought the be simple to fix at this
    point. Luckily I'm not European so I'll be around all of August to
    fix things :-)

    The major stages of this work here are each fronted by a forced
    merge commit whose commit message contains a top-level description
    of the motivations and implementation issues.

    2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
    input.

    3) TCP SYN/ACK performance tweaks from Eric Dumazet.

    4) Add namespace support for netfilter L4 conntrack helpers, from Gao
    Feng.

    5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
    Yuval Mintz.

    6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.

    7) Support for connection tracker helpers in userspace, from Pablo
    Neira Ayuso.

    8) Allow userspace driven TX load balancing functions in TEAM driver,
    from Jiri Pirko.

    9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
    embedded gotos.

    10) TCP Small Queues, essentially minimize the amount of TCP data queued
    up in the packet scheduler layer. Whereas the existing BQL (Byte
    Queue Limits) limits the pkt_sched --> netdevice queuing levels,
    this controls the TCP --> pkt_sched queueing levels.

    From Eric Dumazet.

    11) Reduce the number of get_page/put_page ops done on SKB fragments,
    from Alexander Duyck.

    12) Implement protection against blind resets in TCP (RFC 5961), from
    Eric Dumazet.

    13) Support the client side of TCP Fast Open, basically the ability to
    send data in the SYN exchange, from Yuchung Cheng.

    Basically, the sender queues up data with a sendmsg() call using
    MSG_FASTOPEN, then they do the connect() which emits the queued up
    fastopen data.

    14) Avoid all the problems we get into in TCP when timers or PMTU events
    hit a locked socket. The TCP Small Queues changes added a
    tcp_release_cb() that allows us to queue work up to the
    release_sock() caller, and that's what we use here too. From Eric
    Dumazet.

    15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.

    because a section containing const variables is marked read only and so

    Additional changes to Youichi Yuasa's command line simplication code

    The PowerTV platform uses a non-standard way to get the kernel command
    line--we insert a built-in command line into arcs_cmdline and to
    get additional command line information from the bootloader via a
    pointer in the a1 register. It is necessary to insert a space between
    to the two strings or the last argument from arcs_cmdline and the first
    argument from the bootloader may be inadvertantly combined.

    It is also necessary to set CONFIG_CMDLINE_BOOL to "y" and to set the
    default command line to an empty string to get the simplified code to
    work properly in the PowerTV environment.

    Replace phys_to_dma()/dma_to_phys() looping algorithm with an O(1) algorithm
    The approach taken is inspired by the sparse memory implementation: take a
    certain number of high-order bits off the address them, use this as an
    index into a table containing an offset to the desired address and add
    it to the original value. There is a table for mapping physical addresses
    to DMA addresses and another one for the reverse mapping. The table sizes
    depend on how fine-grained the mappings need to be; Coarser granularity
    less to smaller tables. On a processor with 32-bit physical and DMA
    addresses, with 4 MIB granularity, memory usage is two 2048-byte arrays.
    Each 32-byte cache line thus covers 64 MiB of address space.

    Also, renames phys_to_bus() to phys_to_dma() and bus_to_phys() to
    dma_to_phys() to align with kernel usage.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

    Pre-compute addresses for the basic ASIC registers. This speeds up access
    and allows memory for unused configurations to be freed. In addition,
    uninitialized register addresses will be returned as NULL to catch bad
    usage quickly.
