20ad4fd562 rndis_wlan: use ARRAY_SIZE instead of sizeof when adding 11g rates
While figuring out the TKIP problem I found a bug in the code which adds the 11g
rates. It's using sizeof instead of ARRAY_SIZE to terminate the for loop. This makes
it fall off the end of the rates array start into the frequency array instead. Running
"iwlist rate" should show the problem as there will always be 32 rates with the last
few being bogus.

The following patch will fix it.

96d97f262a kbuild: fix $(src) assignmnet with external modules
When we introduced support for KBUILD_EXTRA_SYMBOLS
we started to include the externam module's kbuild
file when doing the final modpost step.

As external modules often do:
ccflags-y := -I$(src)

We had problems because $(src) was unassinged and
gcc then used the next parameter for -I resulting in
strange build failures.

Fix is to assign $(src) and $(obj) when building
external modules.

a4ed1e41a7 8250 Serial Driver: revert extra IRQ flag definition patch
As Russell pointed out, original patch will break some serial configurations
because of the dependency of the <asm/serial.h> header file.

Revert it first and try to find out other solution later

9c8b28c2ef [POWERPC] Fix DMA nodes in the MPC8610 HPCD device tree
The node for DMA2 in the MPC8610 HPCD device tree has the wrong compatible
properties.  This breaks the DMA driver and the sound driver.

6907fa26d8 [POWERPC] Export empty_zero_page and copy_page in arch/ppc
Currently ext4 and fuse fail to link if modular:
ERROR: "copy_page" [fs/fuse/fuse.ko] undefined!
ERROR: "empty_zero_page" [fs/ext4/ext4dev.ko] undefined!
make[3]: *** [__modpost] Error 1
make[2]: *** [modules] Error 2
make[1]: *** [sub-make] Error 2

While arch ppc exists it may as well compile, so this exports those
symbols (which are already exported in arch/powerpc).

cfab3bdf82 [POWERPC] Add "memory" clobber to MMIO accessors
Gcc might re-order MMIO accessors vs. surrounding consistent
memory accesses, which is a "bad thing", and could break drivers.
This fixes it by adding a "memory" clobber to the MMIO accessors,
which should prevent gcc from doing that reordering.
