Modified files:
sys/vm vnode_pager.c
Log:
Almost nine years ago, when support for 1TB files was introduced in
revision 1.55, the address parameter to vnode_pager_addr() was changed
from an unsigned 32-bit quantity to a signed 64-bit quantity. However,
an out-of-range check on the address was not updated. Consequently,
memory-mapped I/O on files greater than 2GB could cause a kernel panic.
Since the address is now a signed 64-bit quantity, the problem resolution
is simply to remove a cast.
