Rename the `nitems` variable to `num_items` to avoid collisions with the
macro in sys/param.h for counting elements in an array
Similarly, rename `string` to `string_arr` to avoid future collisions with
potential keywords, as well as make it clear that `string_arr` isn't a char*
value, but instead a char** value.

On powerpc64, pointers are 64 bits, so casting from uint32_t changes the integer
width.
The alternative was to use register_t, but I didn't see register_t used as
argument type for any other functions, though didn't look too closely. u_long
was an acceptable alternative. On 64-bit it's 64 bits, on 32-bit it's 32 bits.
powerpc_init() initializes the mmu. Since this may clear pages via
pmap_zero_page(), set the cacheline size before calling into it, so
pmap_zero_page() has the right cacheline size. This isn't completely
necessary now, but will be when 64-bit book-e is completed.

stable/10 doesn't have the if_getdrvflags(9) KPI. Reference the field in the

These are going to be much more efficient on low end embedded systems
but unfortunately they make it .. less convenient to implement correct
bus barriers and debugging. They also didn't implement the register
serialisation workaround required for Owl (AR5416.)
So, just remove them for now. Later on I'll just inline the routines
from ah_osdep.c.
in6_selectif().
The main task of in6_selectsrc() is to return IPv6 SAS (along with
output interface used for scope checks). No data-path code uses
route argument for caching. The only users are icmp6 (reflect code),
ND6 ns/na generation code. All this fucntions are control-plane, so
there is no reason to try to 'optimize' something by passing cached
route into to ip6_output(). Given that, simplify code by eliminating
in6_selectsrc() 'struct route_in6' argument. Since in6_selectif() is
used only by in6_selectsrc(), eliminate its 'struct route_in6' argument,
too. While here, reshape rte-related code inside in6_selectif() to
free lookup result immediately after saving all the needed fields.

Add ro_mtu field to 'struct route' to be able to pass lookup MTU back to
the caller.
Currently, ip6_getpmtu() has 2 totally different use cases:
1) control plane (IPV6_PATHMTU req), where we just need to calculate MTU
and return it, w/o any reusability.
2) Actual ip6_output() data path where we (nearly) always use the provided
route lookup data. If this data is not 'valid' we need to perform another
lookup and save the result (which cannot be re-used by ip6_output()).
Given that, handle 1) by calling separate function doing rte lookup itself.
Resulting MTU is calculated by (newly-added) ip6_calcmtu() used by both
ip6_getpmtu_ctl() and ip6_getpmtu().
For 2) instead of storing ref'ed rte, store mtu (the only needed data
from the lookup result) inside newly-added ro_mtu field.
'struct route' was shrinked by 8(or 4 bytes) in r292978. Grow it again
by 4 bytes. New ro_mtu field will be used in other places like
ip/tcp_output (EMSGSIZE handling from output routines).

problem that led to this temporary workaround (and also so I can properly
cite the PR in the commit this time).
In general this is intended to be a temporary workaround until we can figure
out why including any ram from the last megabyte of the physical address
space leads to a NULL pointer deref. Debugging that is made trickier by the
fact that I couldn't even get a backtrace in ddb.

For rs6000, most memory insns and addi/addis do not allow GPR0 for RA

sure to have a base register other than GPR0.
GCC-4.7 and up handles this with allocating r9 instead of r0.
to generate the phys_avail and dump_avail arrays.
This is a partial fix for the kernel side of the problem mentioned in the
PR. This part handles the cases where comparing start and end addresses of
a block would fail because 32-bit wrap caused the end address to come out
zero if the end of the region is the end of the address space (0xffffffff
with 32-bit vm_paddr_t, but now the code should also work right if we ever
support LPAE with 36-bit addresses).
More work is necessary to make systems with ram at the end of the physical
address space usable, but at least initially it's going to be more like a
workaround than a fix, so this non-hacky part is being committed first.

When restarted, failing syscalls eventually either stop finding the

The ath hal and driver code all assume the world is an x86 or the
bus layer does an explicit bus flush after each operation (eg netbsd.)
However, we don't do that.
So, to be "correct" on platforms like sparc64, mips and ppc (and maybe
ARM, I am not sure), just do explicit barriers after each operation.
Now, this does slow things down a tad on embedded platforms but I'd
rather things be "correct" versus "fast." At some later point if someone
wishes it to be fast then we should add the barrier calls to the HAL and
driver.
