5ec4f1d348 hw/alpha: Provide a PCI-ISA bridge device node
- Move initialization of the ISA bus from typhoon_init() to clipper_init();
  this apsect of device topology is really associated with the individual
  model, not the core logic chipset.  typhoon_init() now returns the IRQ
  to use for the output of the ISA PIC.

- In clipper_init(), instantiate an i82378 instance, and connect its
  PIC output to the ISA IRQ input provided by typhoon_init().  Remove
  the explicit instantiations of i8254 and i82374, as these devices
  are subsumed by the i82378.

3a8233dc1f hw/alpha: Set minimum PCI device ID to 1 to match Clipper IRQ mappings
Since we are emulating a Clipper device topology, we need to set the
minimum PCI device ID to 1, as there is no IRQ mapping for a device
at ID 0 (see sys_dp264.c:clipper_map_irq()).

- Add a 'devfn_min' argument to typhoon_init().  Pass that argument
  along to pci_register_root_bus().
- In clipper_init(), pass PCI_DEVFN(1, 0) as the minimum PCI device
  ID/function.

149009bef4 block-copy: atomic .cancelled and .finished fields in BlockCopyCallState
By adding acquire/release pairs, we ensure that .ret and .error_is_read
fields are written by block_copy_dirty_clusters before .finished is true,
and that they are read by API user after .finished is true.

The atomic here are necessary because the fields are concurrently modified
in coroutines, and read outside.

d0c389d2ce block-copy: add CoMutex lock
Group various structures fields, to better understand what we need to
protect with a lock and what doesn't need it.
Then, add a CoMutex to protect concurrent access of block-copy
data structures. This mutex also protects .copy_bitmap, because its thread-safe
API does not prevent it from assigning two tasks to the same
bitmap region.

Exceptions to the lock:
- .sleep_state is handled in the series "coroutine: new sleep/wake API"
and thus here left as TODO.

- .finished, .cancelled and reads to .ret and .error_is_read will be
protected in the following patch, because are used also outside
coroutines.

- .skip_unallocated is atomic. Including it under the mutex would
increase the critical sections and make them also much more complex.
We can have it as atomic since it is only written from outside and
read by block-copy coroutines.

05d5e12b24 block-copy: streamline choice of copy_range vs. read/write
Put the logic to determine the copy size in a separate function, so
that there is a simple state machine for the possible methods of
copying data from one BlockDriverState to the other.

Use .method instead of .copy_range as in-out argument, and
include also .zeroes as an additional copy method.

While at it, store the common computation of block_copy_max_transfer
into a new field of BlockCopyState, and make sure that we always
obey max_transfer; that's more efficient even for the
COPY_RANGE_READ_WRITE case.

a7b4f8fc09 progressmeter: protect with a mutex
Progressmeter is protected by the AioContext mutex, which
is taken by the block jobs and their caller (like blockdev).

We would like to remove the dependency of block layer code on the
AioContext mutex, since most drivers and the core I/O code are already
not relying on it.

Create a new C file to implement the ProgressMeter API, but keep the
struct as public, to avoid forcing allocation on the heap.

Also add a mutex to be able to provide an accurate snapshot of the
progress values to the caller.

7c4ab60f18 plugins/api: expose symbol lookup to plugins
This is a quality of life helper for plugins so they don't need to
re-implement symbol lookup when dumping an address. The strings are
constant so don't need to be duplicated. One minor tweak is to return
NULL instead of a zero length string to show lookup failed.

66cf70149a scripts/checkpatch: roll diff tweaking into checkpatch itself
Rather than relying on external tweaks lets just do it inside
checkpatch's direct commitish handling which is QEMU specific code
anyway.

ae63ed1691 docs/devel: Add a single top-level header to MTTCG's doc
Without a single top-level header in the .rst file, the index ended
up linking to all of the top-level headers separately. Now the index
links to the top-level header at the beginning of the document and
any inner headers are correctly linked as sub-items in the index.

e8d61f7d21 tests/acceptance: tweak the tcg/kvm tests for virt
Really it's only TCG that can select which GIC model you want, KVM
guests should always be using the "host" version of the GIC for which
QEMU already provides a handy shortcut. Make the KVM test use this and
split the TCG test into it's two versions.

bd80936a4f file-posix: handle EINTR during ioctl
Similar to other handle_aiocb_* functions, handle_aiocb_ioctl needs to cater
for the possibility that ioctl is interrupted by a signal.  Otherwise, the
I/O is incorrectly reported as a failure to the guest.

Try all the possible ioctls for disk size as long as they are
supported, to keep the #if ladder simple.

18473467d5 file-posix: try BLKSECTGET on block devices too, do not round to power of 2
bs->sg is only true for character devices, but block devices can also
be used with scsi-block and scsi-generic.  Unfortunately BLKSECTGET
returns bytes in an int for /dev/sgN devices, and sectors in a short
for block devices, so account for that in the code.

The maximum transfer also need not be a power of 2 (for example I have
seen disks with 1280 KiB maximum transfer) so there's no need to pass
the result through pow2floor.
