      net: convert multicast list to list_head · 22bedad3
      Jiri Pirko authored
      
      Converts the list and the core manipulating with it to be the same as uc_list.
      
      +uses two functions for adding/removing mc address (normal and "global"
       variant) instead of a function parameter.
      +removes dev_mcast.c completely.
      +exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
       manipulation with lists on a sandbox (used in bonding and 80211 drivers)

      Tejun Heo authored
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit 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.

      ibm_newemac: emac_close() needs to call netif_carrier_off() · d3b325f9
      Petri Gynther authored
      
      When ibm_newemac netdev instance is shutdown with "ifconfig down",
      the netdev interface does not go properly down. netif_carrier_ok()
      keeps returning TRUE even after "ifconfig down".
      
      The problem can be seen when ibm_newemac instances are slaves of
      a bonding interface. The bonding interface code uses netif_carrier_ok()
      to determine the link status of its slaves. When ibm_newemac slave is
      shutdown with "ifconfig down", the bonding interface won't detect any
      link status change because netif_carrier_ok() keeps returning TRUE.

      ibm_newemac: Parameterize EMAC Multicast Match Handling · 05781ccd
      Grant Erickson authored
      
      Various instances of the EMAC core have varying: 1) number of address
      match slots, 2) width of the registers for handling address match slots,
      3) number of registers for handling address match slots and 4) base
      offset for those registers.
      
      As the driver stands today, it assumes that all EMACs have 4 IAHT and
      GAHT 32-bit registers, starting at offset 0x30 from the register base,
      with only 16-bits of each used for a total of 64 match slots.
      
      The 405EX(r) and 460EX now use the EMAC4SYNC core rather than the EMAC4
      core. This core has 8 IAHT and GAHT registers, starting at offset 0x80
      from the register base, with ALL 32-bits of each used for a total of
      256 match slots.
      
      This adds a new compatible device tree entry "emac4sync" and a new,
      related feature flag "EMAC_FTR_EMAC4SYNC" along with a series of macros
      and inlines which supply the appropriate parameterized value based on
      the presence or absence of the EMAC4SYNC feature.
      
      The code has further been reworked where appropriate to use those macros
      and inlines.
      
      In addition, the register size passed to ioremap is now taken from the
      device tree:
      
      	c4 for EMAC4SYNC cores
      	74 for EMAC4 cores
      	70 for EMAC cores
      
      rather than sizeof (emac_regs).
      
      Finally, the device trees have been updated with the appropriate compatible
      entries and resource sizes.
      
      This has been tested on an AMCC Haleakala board such that: 1) inbound
      ICMP requests to 'haleakala.local' via MDNS from both Mac OS X 10.4.11
      and Ubuntu 8.04 systems as well as 2) outbound ICMP requests from
      'haleakala.local' to those same systems in the '.local' domain via MDNS
      now work.
