Be ready. > After AHB-support patches went into linux-next (next-20101207), there are now new ath5k patches touching "drivers/net/wireless/ath/ath5k/base.c" on top. For example the patchset from Nick, this would mean revert them, too. Doing so, won't give you a clear answer. BTW, 0008 patch has a big change: drivers/net/wireless/ath/ath5k/base.c | 344 +++++++++++++------------------ Another solution would be to take a previous linux-next where those patches were not in. As you say by yourself 0001..0008 do not hurt, it's 0009 patch (first in patchset) you are speculating on. As I have archived my "compiled" build-trees, I can look at them. AFAICS linux-next (next-20101203) should have wireless-next-2.6 (master-2010-12-02) [1] included. Also, I have to find the fitting linux-image binary and install it, hope I have not purged it from hdd. - Sedat - [1] http://git.kernel.org/?p=linux/kernel/git/linville/wireless-next-2.6.git;a=shortlog;h=refs/tags/master-2010-12-02 $ ls revert-ath5k-patches/000* revert-ath5k-patches/0001-Revert-ath5k-Fix-reset-and-interrupts-for-AHB-type-o.patch revert-ath5k-patches/0002-Revert-ath5k-Add-AHB-bus-support.patch revert-ath5k-patches/0003-Revert-ath5k-Add-initial-registers-values-for-radio-.patch revert-ath5k-patches/0004-Revert-ath5k-Add-a-function-to-read-chipset-s-MAC-re.patch revert-ath5k-patches/0005-Revert-ath5k-Check-if-pci-pdev-struct-is-initialized.patch revert-ath5k-patches/0006-Revert-ath5k-Use-generic-eeprom-read-from-common-ath.patch revert-ath5k-patches/0007-Revert-ath5k-Move-PCI-bus-functions-to-separate-file.patch revert-ath5k-patches/0008-Revert-ath5k-Introduce-ath5k_init_softc-function-as-.patch revert-ath5k-patches/0009-Revert-ath5k-Use-Generic-DMA-for-later-support-of-AH.patch -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
