sys/ia64/ia64 machdep.c
Log:
Use a TR of size 1 << IA64_ID_PAGE_SHIFT instead of 16M to avoid
overlapping TR/TC entries (which results in a machine check). Note
that we don't look at the size of the memory descriptor, because
it doesn't guarantee non-overlap.
With this change, a UP kernel could boot on a Intel Tiger4 machine
with the following options:
options LOG2_ID_PAGE_SIZE=26 # 64M
options LOG2_PAGE_SIZE=14 # 16K
