(XScale mainly) expects the memory located before the kernel to be mapped,
and use it to allocate the page tables, the various stacks, etc.
A better fix would probably be to rewrite the various bla_machdep.c to stop
using that RAM, but I'm not so inclined to do it, especially since I don't
have hardware for all of them.
correctly prepare KGSBASE msr to restore the user descriptor base on
the last swapgs during return to usermode.

mode.
Put the htonl(), htons(), ntohl() and ntohs() declarations under
__POSIX_VISIBLE >= 200112. POSIX.1-2001 and newer require these to be
exposed from <netinet/in.h> (as well as <arpa/inet.h>).
Note that it may be unnecessary to check __POSIX_VISIBLE >= 200112 because
older versions of POSIX and the C standard do not define this header.
However, other places in the same file already perform the check.

flags that has several bits cleared. The RF_WANTED and RF_FIRSTSHARE
bits are invalid in this context, and we want to defer setting RF_ACTIVE
in r_flags until later. This should make rman_get_flags() return
the correct answer in all cases.
Add a KASSERT() to catch callers which incorrectly pass the RF_WANTED
or RF_FIRSTSHARE flags.
Do a strict equality check on the share type bits of flags. In
particular, do an equality check on RF_PREFETCHABLE. The previous
code would allow one type of mismatch of RF_PREFETCHABLE but disallow
the other type of mismatch. Also, ignore the the RF_ALIGNMENT_MASK
bits since alignment validity should be handled by the amask check.
This field contains an integer value, but previous code did a strange
bitwise comparison on it.
Leave the original value of flags unmolested as a minor debug aid.
Change the start+amask overflow check to a KASSERT() since it is just
meant to catch a highly unlikely programming error in the caller.

- Peek host memory twice. Sometimes the PTD status is incorrectly
returned as zero.
- Ensure the host channel is always freed when software TD
is completing.
- Add correct configuration of interrupt polarity and type.
- Set CERR to 2 for asynchronous traffic to avoid having to
reactivate the PTD when a NAK token is received.

- Based on actual usage and on what Linux does, dummy_page.addr should
contain the physical bus address of the dummy page rather than its
virtual one. As a side-effect, correcting this bug fixes compilation
with PAE support enabled by getting rid of an inappropriate cast.
- Also based on actual usage of dummy_page.addr, theoretically Radeon
devices could do a maximum of 44-bit DMA. In reality, though, it is
more likely that they only support 32-bit DMA, at least that is what
radeon_gart_table_ram_alloc() sets up for, too. However, passing ~0
to drm_pci_alloc() as maxaddr parameter translates to 64-bit DMA on
amd64/64-bit machines. Thus, use BUS_SPACE_MAXSIZE_32BIT instead,
which the existing 32-bit DMA limits within the drm2 code spelled as
0xFFFFFFFF should also be changed to.
