Merge support for very early alchemy port. I wouldn't merge this
except I don't want it to get lost when we retire projects/mips.
Should be consiered pre-alpha at this stage. Also, alchemy is now
owned by rmi, but started out life as a separate processor line, so
I'm leaving it in its own directory rather than try to shoe-horn it
into the unrelated rmi directory. Its future location is an open
question.

device in the table based on the count rather than the maxcount.
Also the previous code didn't work properly as it would have been
necessary to reserve the entire maxcount range in order keep later
requests from filling the spare MSIs between count and maxcount,
which would be complicated to unreserve in fire_release_msi().
- For MSIs with filters rather than handlers only don't clear the
event queue interrupt via fire_intr_clear() since given that these
are executed directly would clear it while we're still processing
the event queue, which in turn would lead to lost MSIs.
- Save one level of indentation in fire_setup_intr().
- Correct a bug in fire_teardown_intr() which prevented it from
correctly restoring the MSI in the resource, causing allocation of
a resource representing an MSI to fail after the first pass when
repeatedly loading and unloading a driver module.
Prior to this commit, fread/fwrite calls with size * nmemb > SIZE_MAX
were handled by reading or writing (size_t)(size * nmemb) bytes; for
example, on 32-bit platforms, fread(ptr, 641, 6700417, f) would read 1
byte and indicate that the requested 6700417 blocks had been read.
This commit adds a check for such integer overflows, and treats them as
if an overly large request was passed to read/write; i.e., it sets errno
to EINVAL, sets the error indicator on the file, and returns a short
object count (0, to be specific).
The overflow check involves an integer division, so as a performance
optimization we check first to see if both size and nmemb are less than
2^16; if they are, no overflow is possible and we avoid the division.
We assume here that size_t is at least 32 bits; this appears to be true
on all platforms FreeBSD supports.
Although this commit fixes an integer overflow, it is not likely to have
any security implications, since any program which would be affected by
this bug fix is quite clearly already very confused.

2) Places intr_machdep.c in specfic files.arch pointing to the generic
intr_machdep.c. This allows us to have an architecture dependant
intr_machdep.c (which we will need for RMI) in the machine specific
directory
3) removes intr_machdep.c from files.mips
4) Adds some TARGET_XLR_XLS ifdef's for the machine specific intra_machdep.h. We
may need to look at finding a better place to put this. But first I want to
get this thing compiling.

Like qdivrem, remove the other quad_t support stuff from 64-bit
kernels.

Use FreeBSD/arm approach for handling bus space access: space tag is a pointer
to bus_space structure that defines access methods and hence every bus can
define own accessors. Default space is mips_bus_space_generic. It's a simple
interface to physical memory, values are read with regard to host system
byte order.

we die when we try to link it in.

Copy sys/dev/rmi to sys/mips/rmi/dev [sic]. For devices that are on
only one SoC, or family of SoC, we place them under sys/<vendor>/dev.
I'll fix the build problems this causes as best I can since rmi kernel
require external toolchains due to lack of support for rmi op-codes in
the ancient binutils we have in the tree.
as this only allows us to access file systems that EFI knows about.
With a loader that can only use EFI-supported file systems, we're
forced to put /boot on the EFI system partition. This is suboptimal
in the following ways:
1. With /boot a symlink to /efi/boot, mergemaster complains about
the mismatch and there's no quick solution.
2. The EFI loader can only boot a single version of FreeBSD. There's
no way to install multiple versions of FreeBSD and select one
at the loader prompt.
3. ZFS maintains /boot/zfs/zpool.cache and with /boot a symlink we
end up with the file on a MSDOS file system. ZFS does not have
proper handling of file systems that are under Giant.
Implement a disk device based on the block I/O protocol instead and
pull in file system code from libstand. The disk devices are really
the partitions that EFI knows about.
This change is backward compatible.
