please post your kernel config

I was able to get this to compile by adding 

bio_map15794 bio_map 0 15794 NULL
__vdev_disk_physio55568 __vdev_disk_physio 4 55568 NULL

to the size_overflow_hash.data table

Here is the kernel config.

Kindly look at bug 505594 because it is a related failure.

Do you have problems with the ZFS packages if you unset 

Security options->Grsecurity->Customize Configuration->PaX->Miscellaneous hardening features->Prevent various integer overflows in function size parameters 

or known as CONFIG_PAX_SIZE_OVERFLOW ?

[Comment 7 Matthew Thode ( prometheanfire ) 2014-03-29 17:44:10 UTC]

spender, I think this bug and bug 505594 need to be added to that mapping table you told me about before.

[Comment 8 PaX Team 2014-04-02 00:39:01 UTC]

this was already fixed in PaX/grsec some time ago, please upgrade to something more recent.

What components/packages should be upgraded?
