Current PIO mode makes a kernel crash with CONFIG_HIGHMEM.
Highmem pages have a NULL from sg_virt(sg).
This patch fixes the following problem.
Unable to handle kernel NULL pointer dereference at virtual address
pgd = c0004000

I found the following file was added recently.
"drivers/mmc/host/dw_mmc-pltfm.c"
I feel sorry about that, I didn't catch it.
This file needs to include "linux/scatterlist.h" with current patch
(which is related with "struct sg_mapping_iter"). I'll fix it.
Best regards,

Hi Jaehoon.
Oops, I'll check it.

My kernel is 2.6.38.8, and WiFi is AR6103. I see exactly error message as:

Jeff,
I think the sdhci.c clock setting code was changed a while ago. Maybe revert
that mod and see what happens.
The card is a 24MHz which is rather slow so I would be surprised if that was
it.
The other option is the force enable the High Speed bit in the controller

Hello Jean-Christophe,
A customer using an Atheros AR6103 SDIO WLAN adapter faces this issue.
Sometimes we perform a software reset and he noticed that after he didn't get
sdio irq. The interrupt mask register is also resetted when performing
software reset.

SD card read was failing (data crc error)on some cards at
maximum possible frequency on P1010(CCB frequency set to 400MHz).
Some clock deviations are also observed at this frequency.
Hence reduced the mmc clock freq.
