      net/ethernet: ks8851_mll fix rx frame buffer overflow · 8a9a0ea6
      由 Davide Ciminaghi 提交于 
      At the beginning of ks_rcv(), a for loop retrieves the
header information relevant to all the frames stored
in the mac's internal buffers. The number of pending
frames is stored as an 8 bits field in KS_RXFCTR.
If interrupts are disabled long enough to allow for more than
32 frames to accumulate in the MAC's internal buffers, a buffer
overflow occurs.
This patch fixes the problem by making the
driver's frame_head_info buffer big enough.
Well actually, since the chip appears to have 12K of
internal rx buffers and the shortest ethernet frame should
be 64 bytes long, maybe the limit could be set to
12*1024/64 = 192 frames, but 255 should be safer.

      net/ethernet: convert drivers/net/ethernet/* to use module_platform_driver() · db62f684
      由 Axel Lin 提交于 
      This patch converts the drivers in drivers/net/ethernet/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

      net: remove mm.h inclusion from netdevice.h · b7f080cf
      由 Alexey Dobriyan 提交于 
      Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      由 Tejun Heo 提交于 
      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.

It changes logging macros from:
	dev_<level>(&ks->spidev->dev,
to
	netdev_<level>(ks->netdev,

Comments?

Use netdev_<level>
Use netif_<level>
Use pr_<level>
Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Add missing line to message in ks8851_remove
Change kmalloc/memset(,0) to kzalloc
Remove ks_<level> macros
Consolidation code into set_media_state

      Hello David Miller,

I fix a bug in ks8851_mll driver, which has existed since 2.6.32-rc6.

>From : David J. Choi <david.choi@micrel.com>

Fix a bug that the data pointers in the interrupt handler are set wrong, which is related with the 5th parameter of request_irq().

	-Fix to receive multicast packets by setting the corresponding hardware

	-Fix to re-enable the interface [by interface up command(ifup)] while the
	 interface is down.
	-Fix to be able to down the interface by passing the last parameter
	 correctly to request_irq().
	-Remove to read 4 extra bytes from the receiving queue after reading a
	 packet, even though it does not cause a predictable issue now.
	-Remove occurrences of transmission done interrupt in order to tx
	 throughput enhancement.
	-Enable IP checksum for packet receiving by setting the corresponding
	 hardware bit during initialization.
	-Relocate ks_enable_int()/ks_disable_int() in order not to declare those
	 functions at the beginning of the file.
	-Rename ks_enable()/_disable() to ks_enable_qmu()/ks_disable_qmu() in
	 order to give more meaningful names and relocate them not declaire
	 those functions at the beginning of the file.
