Modified files:
sys/kern link_elf.c
Log:
Check to see if the hash table is present in link_elf_lookup_symbol()
before dereferencing it. Certain corrupt kernel modules might not have
a valid hash table, and would cause a kernel panic when they were loaded.
Instead of panic'ing, the kernel now prints out a warning that it is
missing the symbol hash table.
