As an alternative to commit 818f86b (exec: limit system memory
size, 2013-11-04) let's just make all address spaces 64-bit wide.
This eliminates problems with phys_page_find ignoring bits above
TARGET_PHYS_ADDR_SPACE_BITS and address_space_translate_internal
consequently messing up the computations.
In Luiz's reported crash, at startup gdb attempts to read from address
0xffffffffffffffe6 to 0xffffffffffffffff inclusive. The region it gets
is the newly introduced master abort region, which is as big as the PCI
address space (see pci_bus_init). Due to a typo that's only 2^63-1,
not 2^64. But we get it anyway because phys_page_find ignores the upper
bits of the physical address. In address_space_translate_internal then
diff = int128_sub(section->mr->size, int128_make64(addr));
*plen = int128_get64(int128_min(diff, int128_make64(*plen)));
diff becomes negative, and int128_get64 booms.
The size of the PCI address space region should be fixed anyway.

At the moment, memory radix tree is already variable width, but it can
only skip the low bits of address.
This is efficient if we have huge memory regions but inefficient if we
are only using a tiny portion of the address space.
After we have built up the map, detect
configurations where a single L2 entry is valid.
We then speed up the lookup by skipping one or more levels.
In case any levels were skipped, we might end up in a valid section
instead of erroring out. We handle this by checking that
the address is in range of the resulting section.

Extend skip to 6 bit. As page entry doesn't fit in 16 bit
any longer anyway, extend it to 32 bit.
This doubles node map memory requirements, but follow-up
patches will save this memory.

In preparation for dynamic radix tree depth support, rename is_leaf

The exec.c and translate-all.c radix trees are quite different, and
the exec.c one in particular is not limited to the CPU---it can be
used also by devices that do DMA, and in that case the address space
is not limited to TARGET_PHYS_ADDR_SPACE_BITS bits.
We want to make exec.c's radix trees 64-bit wide. As a first step,
stop sharing the constants between exec.c and translate-all.c.
exec.c gets P_L2_* constants, translate-all.c gets V_L2_*, for
consistency with the existing V_L1_* symbols. Though actually
in the softmmu case translate-all.c is also indexed by physical
addresses...
This patch has no semantic change.

It doesn't make sense for a region to be INT64_MAX in size:
memory core uses UINT64_MAX as a special value meaning
"all 64 bit" this is what was meant here.
While this should never affect the spapr system which at the moment always
has < 63 bit size, this makes us hit all kind of corner case bugs with
sub-pages, so users are probably better off if we just use UINT64_MAX
instead.

qtest uses the icount infrastructure to implement a test-driven vm_clock. This
however is not necessary when using -qtest as a "probe" together with a normal
TCG-, KVM- or Xen-based virtual machine. Hence, split out the call to
configure_icount into a new function that is called only for "-machine
accel=qtest"; and disable those commands when running with an accelerator
other than qtest.
This also fixes an assertion failure with "qemu-system-x86_64 -machine
accel=qtest" but no -qtest option. This is a valid case, albeit somewhat
weird; nothing will happen in the VM but you'll still be able to
interact with the monitor or the GUI.
Now that qtest_init is not limited to an int(void) function, change
global variables that are not used outside qtest_init to arguments.
And finally, cleanup useless parts of include/sysemu/qtest.h. The file
is not used at all for user-only emulation, and qtest is not available
on Win32 due to its usage of sigwait.

- Debug options to disable MSI/X KVM acceleration
- Fix to cleanup MSI-X vectors on shutdown and avoid IRQ route leaks
The KVM-VFIO device support enables KVM to manage how it handles
coherency instructions in the presence of non-coherent I/O. Dave
Airlie had noted that the Nvidia MSI ACK support here may just be
scratching the surface, but it's better than what we have now and

it does enable some users.

We were relying on msix_unset_vector_notifiers() to release all the
vectors when we disable MSI-X, but this only happens when MSI-X is
still enabled on the device. Perform further cleanup by releasing
any remaining vectors listed as in-use after this call. This caused
a leak of IRQ routes on hotplug depending on how the guest OS prepared
the device for removal.

When MSI is enabled on Nvidia GeForce cards the driver seems to
acknowledge the interrupt by writing a 0xff byte to the MSI capability
ID register using the PCI config space mirror at offset 0x88000 from
BAR0. Without this, the device will only fire a single interrupt.
VFIO handles the PCI capability ID/next registers as virtual w/o write
support, so any write through config space is currently dropped. Add
a check for this and allow the write through the BAR window. The
registers are read-only anyway.

SMTP does not preserve newlines. This is normally not a problem if the
email body uses DOS or UNIX newlines consistently. In 051.out we mix
UNIX newlines with DOS newlines (since QEMU monitor output uses \r\n).
This patch filters the QEMU monitor output so the golden master file
uses UNIX newlines exclusively.
The result is that patches touching 051.out will apply cleanly without
mangling newlines after this commit.

This patch drops a special case where aio_poll(ctx, true) returns false
instead of blocking if no file descriptors are waiting on I/O. Now it
is possible to block in aio_poll() to wait for aio_notify().
This change eliminates busy waiting. bdrv_drain_all() used to rely on
busy waiting to completed throttled I/O requests but this is no longer
required so we can simplify aio_poll().
Note that aio_poll() still returns false when aio_notify() was used. In
other words, stopping a blocking aio_poll() wait is not considered
making progress.
Adjust test-aio /aio/bh/callback-delete/one which assumed aio_poll(ctx,
true) would immediately return false instead of blocking.

Since cc0681c454 ("block: Enable the new
throttling code in the block layer.") bdrv_drain_all() no longer spins.
The code used to look as follows:
do {
busy = qemu_aio_wait();
/* FIXME: We do not have timer support here, so this is effectively
* a busy wait.
*/
QTAILQ_FOREACH(bs, &bdrv_states, list) {
while (qemu_co_enter_next(&bs->throttled_reqs)) {
busy = true;
}
}
} while (busy);
Note that throttle requests are kicked but I/O throttling limits are
still in effect. The loop spins until the vm_clock time allows the
request to make progress and complete.
The new throttling code introduced bdrv_start_throttled_reqs(). This
function not only kicks throttled requests but also temporarily disables
throttling so requests can run.
The outdated FIXME comment can be removed. Also drop the busy = true
assignment since we overwrite it immediately afterwards.

Adding xhci support to seabios made it jump over the 128k line.
Changing the bios size breaks migration, so we have to keep a
128k seabios binary for old machine types. New machine types can
use a large 256k bios which should be big enougth for a while.
This patch updates the seabios build process to build seabios twice,
once full featured and once with xen and xhci turned off so the
resulting binary is small enougth to fit into 128k.

However, before this patch the CPUID worked fine -- the .offset
field contained the size _and_ was stored in the register that
is supposed to hold the size (eax), and likewise the .size field
contained the offset _and_ was stored in the register trhat is
supposed to hold the offset (ebx).

since the convert process is basically a sync operation it might
be benificial in some case to change the hardcoded I/O buffer
size to a greater value.
This patch increases the I/O buffer size if the output
driver advertises an optimal transfer length or discard alignment
that is greater than the default buffer size of 2M.
