I solved this adding the extern atomic64_set prototype in
backport-include/asm/atomic.h, atomic64_read and atomic64_add_return
were defined there but atomic64_set was missing
Hit the send button just before reading this. Oh, well.

This time I don't understand what is going on with the error:
/root/modules/backports-3.14-1/net/mac80211/key.c:813: error: implicit
declaration of function 'atomic64_set'
If I search for this function definition I see it is in
compat_atomic.c file:
wsos-sdk:~/modules/backports-3.14-1# grep -r --include="*.c"
atomic64_set .
./net/mac80211/key.c: atomic64_set(&key->u.ccmp.tx_pn, pn64);
./net/mac80211/key.c: atomic64_set(&key->u.aes_cmac.tx_pn, pn64);
./compat/compat_atomic.c:void atomic64_set(atomic64_t *v, long long i)
./compat/compat_atomic.c:EXPORT_SYMBOL_GPL(atomic64_set);
Now I search for it in the compat Makefile:
wsos-sdk:~/modules/backports-3.14-1# grep compat_atomic.o compat/Makefile
compat-$(CPTCFG_BACKPORT_BUILD_GENERIC_ATOMIC64) += compat_atomic.o
And I see in .config that I do have that config option enabled:
wsos-sdk:~/modules/backports-3.14-1# grep
BACKPORT_BUILD_GENERIC_ATOMIC64 .config
CPTCFG_BACKPORT_BUILD_GENERIC_ATOMIC64=y
and it works because I see tha the compat_atomic.o is generated during
the compilation so, I guess that the problem is exporting the symbol
with EXPORT_SYMBOL_GPL(atomic64_set)
any clue about how to solve this?

Hi,
after a bit more investigation I found this:
wsos-sdk:~/modules/backports-3.14-1# grep compat_firmware_class
compat/Makefile
obj-$(CPTCFG_BACKPORT_BUILD_FW_LOADER) += compat_firmware_class.o
so I looked in compat/Kconfig and found this (I didn't find it before
because I grep with the CPTCFG_ header):
config BACKPORT_BUILD_FW_LOADER
tristate
depends on m
# RHEL6, starting from 6.0, backports the FW loader already
depends on !BACKPORT_RHEL_KERNEL_6_0
depends on !FW_LOADER || BACKPORT_KERNEL_2_6_33
default m if BACKPORT_FW_LOADER
default m if BACKPORT_USERSEL_BUILD_ALL
config BACKPORT_FW_LOADER
bool
from here I understand that I have to enable de BACKPORT_FW_LOADER
option.
I haven't found it in menuconfig so I changed it manually in
compat/Kconfig to 'def_bool y'
Now the error went away but a new one appeared:

I'll try to figure out what happens this time

Hi,
when I try to compile backports-3.14-1 in a 2.6.30 kernel I get this

I saw that in backport-include/linux/firmware.h there is a
pre-compiler directive to use the backport's version of
request_firmware_nowait function:
#if defined(CPTCFG_BACKPORT_BUILD_FW_LOADER_MODULE)
#define request_firmware_nowait LINUX_BACKPORT(request_firmware_nowait)
But I haven't found where the CPTCFG_BACKPORT_BUILD_FW_LOADER_MODULE
is defined.
I just ran:
make defconfig-ath9k
make
Am I missing a previous configuration step?
Thanks!
