Hi,

I've just rebased my personal kernel tree to what will soon be 4.12-rc1
and I'm getting my dmesg log filled with the following errors:

[   32.528271] brcmfmac: brcmf_sdio_rxglom: sublen 524 not multiple of 8
[   32.528296] brcmfmac: brcmf_sdio_rxglom: sublen 84 not multiple of 8
[   33.063241] brcmfmac: brcmf_sdio_rxglom: sublen 1492 not multiple of 8

Other brcmfmac dmesg messages:

[   16.020013] brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Jul 17 2013 07:36:07 version 6.10.197.71 (r412987) FWID 01-882d2634

This is on a Asus T100TA which uses a 43241b1

Ok, this seems to be a regression caused by:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6e84ab604bded
"brcmfmac: properly align buffers on certain platforms with 64 bit DMA"

I believe this may need a different fix then that.

Regards,

Hans
