Since commit f0e98c387e61de00646be31fab4c2fa0224e1efb ("[SPARC]: Fix
link errors with gcc-4.3") the MNA trap handler does not emulate
stores to unaligned addresses correctly. MNA operation from both
kernel and user space are affected.
A typical effect of this bug is nr_frags in skbs are overwritten
during buffer copying/checksum-calculation, or maximally 6 bytes
of data in the network buffer will be overwitten with garbage.

Reported by Adrian Bunk.
Just like in changeset a3f9985843b674cbcb58f39fab8416675e7ab842
("[SPARC64]: Move kernel unaligned trap handlers into assembler
file.") we have to move the assembler bits into a seperate
asm file because as far as the compiler is concerned
these inline bits we're doing in unaligned.c are unreachable.
