#
# Stage one of module building created the following:
# a) The individual .o files used for the module
# b) A <module>.o file which is the .o files above linked together
# c) A <module>.mod file in $(MODVERDIR)/, listing the name of the
#    the preliminary <module>.o file, plus all .o files

# Stage 2 is handled by this file and does the following
# 1) Find all modules from the files listed in $(MODVERDIR)/
# 2) modpost is then used to
# 3)  create one <module>.mod.c file pr. module
# 4)  create one Module.symvers file with CRC for all exported symbols
# 5) compile all <module>.mod.c files
# 6) final link of the module to a <module.ko> file

# Step 3 is used to place certain information in the module's ELF
# section, including information such as:
#   Version magic (see include/linux/vermagic.h for full details)
#     - Kernel release
#     - SMP is CONFIG_SMP
#     - PREEMPT is CONFIG_PREEMPT
#     - GCC Version
#   Module info
#     - Module version (MODULE_VERSION)
#     - Module alias'es (MODULE_ALIAS)
#     - Module license (MODULE_LICENSE)
#     - See include/linux/module.h for more details

# Step 4 is solely used to allow module versioning in external modules,
# where the CRC of each module is retrieved from the Module.symvers file.

# KBUILD_MODPOST_WARN can be set to avoid error out in case of undefined
# symbols in the final module linking stage
# KBUILD_MODPOST_NOFINAL can be set to skip the final link of modules.
# This is solely useful to speed up test compiles

<div class='commit-subject'>Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net</div><div class='commit-msg'>Pull networking fixes from David Miller:

 1) Fix handling of interrupt status in stmmac driver. Just because we
    have masked the event from generating interrupts, doesn't mean the
    bit won't still be set in the interrupt status register. From Alexey
    Brodkin.

 2) Fix DMA API debugging splats in gianfar driver, from Arseny Solokha.

 3) Fix off-by-one error in __ip6_append_data(), from Vlad Yasevich.

 4) cls_flow does not match on icmpv6 codes properly, from Simon Horman.

 5) Initial MAC address can be set incorrectly in some scenerios, from
    Ivan Vecera.

 6) Packet header pointer arithmetic fix in ip6_tnl_parse_tlv_end_lim(),
    from Dan Carpenter.

 7) Fix divide by zero in __tcp_select_window(), from Eric Dumazet.

 8) Fix crash in iwlwifi when unregistering thermal zone, from Jens
    Axboe.

 9) Check for DMA mapping errors in starfire driver, from Alexey
    Khoroshilov.
