While the comment removed in this patch claims board_n800.c uses
"cx3110x", it was never merged to mainline like this. Mainlined board
files for Nokia N8x0 devices are expected "p54spi", and thus don't
work because the modalias is "cx3110x". To my knowledge, these
devices are the only real-world use of p54spi, and will not work
without this change. Tested against my Nokia N810.

This patch removes from drivers/net/ all the unnecessary
return; statements that precede the last closing brace of
void functions.
It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.
It also does not remove null void functions with return.
Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'
with some cleanups by hand.
Compile tested x86 allmodconfig only.

Quote from comment #17:
"The problem is the innocent looking moving of the tx processing to
after the rx processing in the tasklet. Quoting from the changelog:
This patch does it the same way, except that it also prioritize
rx data processing, simply because tx routines *can* wait.
This is causing an issue with us referencing already freed memory,
because some skb's we transmit, we immediately receive back, such
as those for reading the eeprom (*) and getting stats.
What can happen because of the moving of the tx processing to after
the rx processing is that when the tasklet first runs after doing a
special skb tx (such as eeprom) we've already received the answer
to it.
Then the rx processing ends up calling p54_find_and_unlink_skb to
find the matching tx skb for the just received special rx skb and
frees the tx skb.
Then after the processing of the rx skb answer, and thus freeing
the tx skb, we go process the completed tx ring entires, and then
dereference the free-ed skb, to see if it should free free-ed by
p54p_check_tx_ring()."

Hans de Goede identified a bug in p54p_check_tx_ring:
there are two ring indices. 1 => tx data and 3 => tx management.
But the old code had a constant "1" and this resulted in spurious
dma unmapping failures.

This patch fixes an old problem, which - under certain
circumstances - could cause the device to become
unresponsive.
most of p54pci's rx-ring management is implemented in just
two distinct standalone functions. p54p_check_rx_ring takes
care of processing incoming data, while p54p_refill_rx_ring
tries to replenish all depleted communication buffers.
This has always worked fine on my fast machine, but
now I know there is a hidden race...
The most likely candidate here is ring_control->device_idx.
Quintin Pitts had already analyzed the culprit and posted
a patch back in Oct 2009. But sadly, no one's picked up on this.
( https://patchwork.kernel.org/patch/53079/ [2 & 3] ).
This patch does the same way, except that it also prioritize
rx data processing, simply because tx routines *can* wait.

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.

This patch moves the tx cleanup routines out of the critical
interrupt context and into the (previously known as rx) tasklet.
The main goal of this operation is to remove the extensive
usage of spin_lock_irqsaves in the generic p54common library.
The next step would be to modify p54usb to do the
rx processing inside a tasklet (just like usbnet).

A long time ago, a user reported several crashes due to
data corruptions which are likely the result of a
not-100%-supported, or faulty? PCI bridge.
( http://patchwork.kernel.org/patch/53004/ )
This patch fixes entry #1.
"1. p54p_check_rx_ring - skb_over_panic: Under a ping flood
or just left running for a bit would panic with a skb_over_panic."
As described in the mail: The invalid frame length causes
skb_put to bailout and trigger a crash.
Note:
Simply dropping the frame is problematic, because if its content
contains a tx feedback we would lose some portion of the device
memory space.... And the driver/mac80211 should handle all other
invalid data.
