Our code to identify syscall numbers has some issues:
* for Thumb mode, we never need the immediate value from the insn,
but we always read it anyway
* bad immediate values in the svc insn should cause a SIGILL, but we
were abort()ing instead (via "goto error")
We can fix both these things by refactoring the code that identifies
the syscall number to more closely follow the kernel COMPAT_OABI code:
* for Thumb it is always r7
* for Arm, if the immediate value is 0, then this is an EABI call
with the syscall number in r7
* otherwise, we XOR the immediate value with 0x900000
(ARM_SYSCALL_BASE for QEMU; __NR_OABI_SYSCALL_BASE in the kernel),
which converts valid syscall immediates into the desired value,
and puts all invalid immediates in the range 0x100000 or above
* then we can just let the existing "value too large, deliver
SIGILL" case handle invalid numbers, and drop the 'goto error'

The kernel has different handling for syscalls with invalid

* other out of range syscalls cause a SIGILL
(see the kernel's arch/arm/kernel/traps.c:arm_syscall())
Implement this distinction. (Note that our code doesn't look

We incorrectly treat SVC 0xf0002 as a cacheflush request (which is a
NOP for QEMU). This is the wrong syscall number, because in the
svc-immediate OABI syscall numbers are all offset by the
ARM_SYSCALL_BASE value and so the correct insn is SVC 0x9f0002.
(This is handled further down in the code with the other Arm-specific
syscalls like NR_breakpoint.)
When this code was initially added in commit 6f1f31c069 in
2004, ARM_NR_cacheflush was defined as (ARM_SYSCALL_BASE + 0xf0000 + 2)
so the value in the comparison took account of the extra 0x900000
offset. In commit fbb4a2e371 in 2008, the ARM_SYSCALL_BASE
was removed from the definition of ARM_NR_cacheflush and handling
for this group of syscalls was added below the point where we subtract
ARM_SYSCALL_BASE from the SVC immediate value. However that commit
forgot to remove the now-obsolete earlier handling code.
Remove the spurious ARM_NR_cacheflush condition.

In linux-user/arm/cpu-loop.c we incorrectly treat EXCP_BKPT similarly
to EXCP_SWI, which means that if the guest executes a BKPT insn then
QEMU will perform a syscall for it (which syscall depends on what
value happens to be in r7...). The correct behaviour is that the
guest process should take a SIGTRAP.
This code has been like this (more or less) since commit
06c949e62a in 2006 which added BKPT in the first place. This is
probably because at the time the same code path was used to handle
both Linux syscalls and semihosting calls, and (on M profile) BKPT
with a suitable magic number is used for semihosting calls. But
these days we've moved handling of semihosting out to an entirely
different codepath, so we can fix this bug by simply removing this
handling of EXCP_BKPT and instead making it deliver a SIGTRAP like
EXCP_DEBUG (as we do already on aarch64).

Include actions for --add, --remove, --clear, --enable, --disable, and
--merge (note that --clear is a bit of fluff, because the same can be
accomplished by removing a bitmap and then adding a new one in its
place, but it matches what QMP commands exist). Listing is omitted,
because it does not require a bitmap name and because it was already
possible with 'qemu-img info'. A single command line can play one or
more bitmap commands in sequence on the same bitmap name (although all
added bitmaps share the same granularity, and and all merged bitmaps
come from the same source file). Merge defaults to other bitmaps in
the primary image, but can also be told to merge bitmaps from a
distinct image.
While this supports --image-opts for the file being modified, I did
not think it worth the extra complexity to support that for the source
file in a cross-file merges. Likewise, I chose to have --merge only
take a single source rather than following the QMP support for
multiple merges in one go (although you can still use more than one
--merge in the command line); in part because qemu-img is offline and
therefore atomicity is not an issue.
Upcoming patches will add iotest coverage of these commands while
also testing other features.

Upcoming patches want to add some basic bitmap manipulation abilities
to qemu-img. But blockdev.o is too heavyweight to link into qemu-img
(among other things, it would drag in block jobs and transaction
support - qemu-img does offline manipulation, where atomicity is less
important because there are no concurrent modifications to compete
with), so it's time to split off the bare bones of what we will need
into a new file block/monitor/bitmap-qmp-cmds.o.
This is sufficient to expose 6 QMP commands for use by qemu-img (add,
remove, clear, enable, disable, merge), as well as move the three
helper functions touched in the previous patch. Regarding
MAINTAINERS, the new file is automatically part of block core, but
also makes sense as related to other dirty bitmap files.

Upcoming patches will enhance bitmap support in qemu-img, but in doing
so, it turns out to be nice to suppress output when persistent bitmaps
make no sense (such as on a qcow2 v2 image). Add a hook to make this
easier to query.
This patch adds a new callback .bdrv_supports_persistent_dirty_bitmap,
rather than trying to shoehorn the answer in via existing callbacks.
In particular, while it might have been possible to overload
.bdrv_co_can_store_new_dirty_bitmap to special-case a NULL input to
answer whether any persistent bitmaps are supported, that is at odds
with whether a particular bitmap can be stored (for example, even on
an image that supports persistent bitmaps but has currently filled up
the maximum number of bitmaps, attempts to store another one should
fail); and the new functionality doesn't require coroutine safety.
Similarly, we could have added one more piece of information to
.bdrv_get_info, but then again, most callers to that function tend to
already discard extraneous information, and making it a catch-all
rather than a series of dedicated scalar queries hasn't really
simplified life.
In the future, when we improve the ability to look up bitmaps through
a filter, we will probably also want to teach the block layer to
automatically let filters pass this request on through.

available. On Windows this function returns keyboard scancodes
and some extended flags. These raw keyboard scancodes are much
better suited for this use case than the half-cooked win32
virtual-key codes because scancodes report the key position on
the keyboard and the positions are independent of national
language settings.

Without keyboard grab Windows currently handles the two win keys
and the key events are also sent to the guest. This is undesir-
able. Only one program should handle key events. This patch ap-
plies commit c68f74b02e "win32: do not handle win keys when the
keyboard is not grabbed" from project spice-gtk to ui/gtk.c to
fix this problem.
