linux-user: Safety belt for h2g
h2g can only work on 64-bit hosts if the provided address is mappable to
the guest range. Neglecting this was already the source for several
bugs. Instrument the macro so that it will trigger earlier in the
future (at least as long as we have this kind of mapping mechanism).

SH4: SCI improvement
This patch simply implement one register of SH4's SCI := Serial Communication Interface.
R2D evaluation board uses SCI for SPI connection. So, Linux kernel for R2D with
default configuration causes a QEMU assertion failure when it initializes SPI driver.
This patch avoids it and reduces the kernel config modification work for QEMU.
Completing SCI implementation task is left. Other board support is desirable to confirm
this task, which uses SCI for a serial terminal.

SH4: Implement FD bit
SH4 manual say that if a floating point instruction is executed while
FD bit in the status register is 1, an exception should be raised. QEMU
presently does not do that, so the kernel does not initialize FP state
for any thread, nor does it save/restore FP state. The most apparent
consequence is that while recent gcc/libc expect double-precision mode
to be set by kernel, they run in single-precision mode, and all FP code
produces wrong values.
This patch fixes this. It also fixes a couple of places where PC was
not updated before handling an exception, although both those places
deal with invalid instruction and don't lead to any user-visible bugs.

SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).
Main purpose of this is to delete
*physical = address & 0x1fffffff;
at target-sh4/helper.c:449, using new mmio rule introduced by #5849
This masking is a nice trick to realize P4/A7 duality of SH registers.
But, IMHO, it is logically wrong.
Most of SH4 cpu control registers in P4 area(0xfc000000...0xffffffff) have
one more address called A7 which is usually P4 address with upper 3bits masked.
This is an address only appears in TLB's physical address part.
Current code use trick writing drivers as if they are really in A7
(that's why you see many *_A7 in hw/sh*.c), and using translation P4 to A7.

LSI53C895A: Handle empty SCRIPTS opcode (Justin Chevrier)
Basically after each DMA transfer the Openserver driver would issue an
empty (0) SCRIPTS opcode. As the opcode is essentially a NOP it has no
second DWORD and therefore the DSP should only be incremented by 4 bytes
instead of the 8 bytes we currently do.
Here's a snippet of the log:
lsi_scsi: Data ready tag=0x100d9 len=16384
...
lsi_scsi: SCRIPTS dsp=
068c5e50 opcode
01000400 arg
07a09000
lsi_scsi: DMA addr=0x07a09000 len=1024
lsi_scsi: SCRIPTS dsp=
068c5e58 opcode
00000000 arg
01000400
lsi_scsi: Wrong phase got 1 expected 0
Note the 2nd DWORD after the empty opcode; the next opcode in the DMA
transfer sequence. As can be expected the address after that has the next
DMA address to use.
After the attached patch the DMA transfer is able to complete successfully:
lsi_scsi: SCRIPTS dsp=
068c5e50 opcode
01000400 arg
07a0d000
lsi_scsi: DMA addr=0x07a0d000 len=1024

068c5e5c opcode

qcow2 writes a cluster reference count on every cluster update. This causes
performance to crater when using anything but cache=writeback. This is most
noticeable when using savevm. Right now, qcow2 isn't a reliable format
regardless of the type of cache your using because metadata is not updated in

Change order of metadata update to prevent loosing guest data because of unexpected exit (Gleb Natapov)
Currently the order is this (during cow since it's the interesting case):
1. Decrement refcount of old clusters
2. Increment refcount for newly allocated clusters
3. Copy content of old sectors that will not be rewritten
4. Update L2 table with pointers to new clusters
5. Write guest data into new clusters (asynchronously)
There are several problems with this order. The first one is that if qemu
crashes (or killed or host reboots) after new clusters are linked into L2
table but before user data is written there, then on the next reboot guest
will find neither old data nor new one in those sectors and this is not
what gust expects even when journaling file system is in use. The other
problem is that if qemu is killed between steps 1 and 4 then refcount
of old cluster will be incorrect and may cause snapshot corruption.
The patch change the order to be like this:
1. Increment refcount for newly allocated clusters
2. Write guest data into new clusters (asynchronously)
3. Copy content of old sectors that were not rewritten
4. Update L2 table with pointers to new clusters
5. Decrement refcount of old clusters
Unexpected crash may cause cluster leakage, but guest data should be safe.

Exclude unix: from vnc call to unix_listen() (Ryan Harper)
When using an existing unix socket like:
-vnc unix:/tmp/file1Y2nY2
qemu fails to bind a unix socket because the vnc call to unix_listen includes
the unix: prefix and stores that in the unix.sun_path. The fix is to not pass
in unix: for the filename (same way qemu-char.c does it).
