e8234cfef6 preload_search_info: make sure mod is set
Add a check to preload_search_info to make sure mod is set. Most of the
callers of preload_search_info don't check that the mod parameter is
set, which can cause page faults. While at it, remove some now unnecessary
checks before calling preload_search_info.

278e79707e Provide convenience function for obtaining MODINFO_ADDR and MODINFO_SIZE
attributes for preloaded modules/images. In particular, MODINFO_ADDR has
the added complexity of not always being relocated properly. Rather than
kluging this in the various components that are affected, we handle it
in a centralized place (preload_fetch_addr()). To that end, expose a new
variable, preload_addr_relocate, that MD initialization code can set and
that turns the address attribute into a valid kernel VA.

Architectures that need the relocation: arm & powerpc (at least).
Components that can utilize this: acpi(4), md(4), fb(4), pci(4), ZFS, geli.

60ae52f785 Use ISO C99 integer types in sys/kern where possible.
There are only about 100 occurences of the BSD-specific u_int*_t
datatypes in sys/kern. The ISO C99 integer types are used here more
often.

2a26e9ea83 Align to sizeof(long) rather than sizeof(int32_t). It needs to be
long because this code is shared with the alpha.  I hope the alpha can
read 32 bit ints at 32 bit alignment (vs. 64 bit alignment).

2da2eeacee Relocate a few extra addresses that are stored as physical addresses via
the boot loader.

e4f1a52f7a Updates for alignment rounding. XXX this is highly machine dependent and
should probably be moved to i386/i386/link_machdep.c (and the same for the
alpha).
Implement "deleting" a preloaded module by destroying it's tags. This is a
hack.  We cannot reuse the data, it's been destroyed by relocation,
statically initialized variables have been modified, etc.  Note that to
reclaim the load space is going to be more machine-dependent work.
Implement a relocate hook for machdep.c to call so that the physical
addresses get converted to the equivalent KVM addresses.
