The commit fc2bf44972
changed the type of val argument of the function gt64120_writel()
from uint32_t to uint64_t, so we need to change the corresponding
length modifier from "%x" to "%" PRIx64.

We are mapping ESCC to a static (incorrect) address on machine init. This
overlaps with our vram, rendering the screen barely usable.
Since openBIOS is clever enough to map ESCC to where it needs to be, we can
just drop that invalid map and everyone's happy.

x86 cannot provide an optimized generic deposit implementation. But at
least for a few special cases, namely for writing bits 0..7, 8..15, and
0..15, versions using only a single instruction are feasible.
Introducing such limited support improves emulating 16-bit x86 code on
x86, but also rarer cases where 32-bit or 64-bit code accesses bytes or
words.

Include config.h in softfloat.c, so that the target specific ifdefs in
softfloat-specialize.h are evaluated correctly. This was accidentally
broken in commit 789ec7ce2 when config-target.h was removed from
softfloat.h, and means that most targets will have been returning the
wrong results for calculations involving NaNs.

The two new variables "arp_requested" and "expiration_date" in the mbuf
structure have been added after the variable-sized "m_dat_" array. The
variables have to be added before the m_dat_ array instead.
Without this patch, the expiration_date gets clobbered by code that
accesses the m_dat_ array.
I experienced this problem with the code in slirp/tftp.c: The
tftp_send_data() function created a new packet with the m_get()
function (which fills-in a default expiration_date value). Then the
TFTP code cleared the data section of the packet, which accidentially
also cleared the expiration_date. This zeroed expiration_date then
finally causes the packet to be discarded during if_start(), so that
TFTP packets were not transmitted anymore.

i8259 is an ISA device (or at least, depends on the ISA infrastructure to
register its ioport); and the ISA bus is supplied by piix4. Later patches
make this dependency explicit.
Use qemu_irq_proxy() to stop the cycle by adding an extra layer of
indirection.
