[IA64] bte_copy of BTE_MAX_XFER trips BUG_ON.
BTE_MAX_XFER is wrong. It is one greater than the number of cache
lines the BTE is actually able to transfer. If you request a transfer
of exactly BTE_MAX_XFER size, you trip a very cryptic BUG_ON() which
should certainly be made more clear.
This patch fixes that constant and also cleans up the BUG_ON()s in
arch/ia64/sn/kernel/bte.c to test one condition per line.
