I've removed Haijun's three patches from mmc-next while they're reworked
to fix this.  Thanks!

[Zhang Haijun-B42677]

Hi,Chris

I had update my branch linux-mmc and test, there is no such err.
As u64 need the macro div_u64 in "include/linux/math64.h"

#ifndef div_u64
static inline u64 div_u64(u64 dividend, u32 divisor)
{
        u32 remainder;
        return div_u64_rem(dividend, divisor, &remainder);
}
#endif

As different vendor may redefine div_u64_rem or remove the func div_u64, it's possible.
In driver/mmc/ all func use data->timeout_ns without define div_u64 or not use div_u64 to divide will encounter this err. So I'm not sure which reason bring about this err.

Regards
Haijun.

RE: [mmc:mmc-next 45/63] of_iommu.c:(.text+0x114dbc): undefined reference to `__aeabi_uldivmod'

[Zhang Haijun-B42677]

Hi Chris

I see patches modified the public C file and Powerpc Host C file. But it also used by other host C file.
So need to replace all the u64 division by macro div_u64 to avoid this error.
Two new patches had send and reviewed by Anton.
I think they can fix the `__aeabi_uldivmod' error.
All the patches work fine on my branch.

Regards
Haijun.

RE: [mmc:mmc-next 45/63] of_iommu.c:(.text+0x114dbc): undefined reference to `__aeabi_uldivmod'

[Huang Changming-R66093]

Hi, Robot
I don't find the `__aeabi_uldivmod' in branch 'mmc-next' of linux-mmc tree.
Could you point out which file use it?

This patch just use the 'div_u64' to calculate the timeout in order to avoid overflow.

Best Regards
Jerry Huang

Thanks, Fengguang, did you use the same environment as Chris?
If so that's just the reason caused the err.

[Fengguang Wu]

I don't understand your question... The question is, did Chris use the
same environment detailed in the original report? Did he check out the
right commit (d29254e21ddddee37b3c8525817398d96d6403f3) and used the
right config (omap2plus_defconfig)?
