pvrsrvkm failing on kernel 3.14.26 for am3359

Folks,

I have recently updated my meta-ti daisy branch and noticed that
omap3-sgx-modules are not being loaded.

Here is the log for 3.14.26 kernel (from meta-ti commit
1d46274416c3b50808590963bdb6c157d9d7c745):

pvrsrvkm: Unknown symbol v7_dma_map_area (err 0)
pvrsrvkm: Unknown symbol v7_dma_flush_range (err 0)
insmod: ERROR: could not insert module
/lib/modules/3.14.26/kernel/drivers/gpu/pvr/pvrsrvkm.ko: Unknown symbol in
module
Could not find pvrsrvkm driver


The 3.14.25 kernel version (from meta-ti commit
31348244882a8defb640af75119ba275d9915f09) is OK.

I'm using the default kernel configuration.

     arm: Export cache flush management symbols when !MULTI_CACHE

     When compiling a kernel without CONFIG_MULTI_CACHE enabled the
     dma access functions end up not being exported. Fix it.

The fix finally got merged to the kernel yesterday and will be picked up by
