Too involved for me to look into.
I cooked up following very minimal patch - if you agree can you then please
forward/take care of it.

Subject: video: fix section mismatch warning in promcon

Fix the following warnings in promcon:
WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x480): Section mismatch: reference to .init.data:promfont_unitable (between 'promcon_init_unimap' and 'promcon_init')
WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x488): Section mismatch: reference to .init.data:promfont_unitable (between 'promcon_init_unimap' and 'promcon_init')
WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x48c): Section mismatch: reference to .init.data:promfont_unicount (between 'promcon_init_unimap' and 'promcon_init')
WARNING: o-sparc64/drivers/video/console/built-in.o(.text+0x490): Section mismatch: reference to .init.data:promfont_unicount (between 'promcon_init_unimap' and 'promcon_init')

The warnings happens because the function: promcon_init_unimap()
references promfont_unitable and promfont_unicount which are marked
__initdata by the conmakehash command in the drivers/video/console/Makefile

Fix the warning by removing the __initdata marker on the two variables.
